EXAMPLE 1

(53) An item of footwear of the present invention that is in the form of a barefoot trainer 1 (i.e. without a user needing to wear shoes) is shown in FIG. 1.

(54) It can be seen that an upper part of the barefoot trainer 1 is in the form of a brace 100, which acts as an ankle restrictor, as discussed later. The brace 100 of the trainer 1 is shown in a position where it is about to be slotted into three apertures (slots 104) in a base 200, with the three downwardly pointing arrows 101 illustrating how it is slotted into position.

(55) The brace 100 is shaped to fit around the back of the leg of a wearer of the training aid 1. It braces the ankle in position. It may optionally include padding, lining or cushioning for the comfort of a user, although in this embodiment this is not shown for simplicity.

(56) In this embodiment the brace 100 includes a rigid curved element 107. This has a posterior part 105 that fits closely against the back of the heel of a wearer and extends above the heel. In this figure it extends to just below the calf region. (However in other embodiments, as discussed later, a strut that is longer may be provided and may, for example, reach the calf region.)

(57) In this embodiment the curved element 107 includes a lower part 106 that extends below the heel of the user so as to lie underneath a portion of the user's foot, including the heel and midsole portion. The curved element 107 is formed of relatively rigid material so that the ankle can be held securely in place without substantial movement hereof when the brace 100 is in use. The curved element may, for example, be formed of a metal, a plastics material or a composite material (e.g. carbon fibre). The material should be resilient. (A small amount of flex may be permitted, as long as the ankle is kept substantially immobile.)

(58) In order to achieve fastening, the brace 100 includes an upper fastener 102 that can be fastened around the shin region of the lower leg of a user and a lower fastener 103 that can be fastened over a part of lower part of the foot (typically over a mid-foot portion of the foot between the heel and the toes).

(59) In this embodiment each fastener 102, 103 comprises two connecting parts that are connected together by a hook an eye arrangement, such as by Velcro material. The connection is not show in the figure, because it is on the other side of the item of footwear (the right side), relative to the side that is shown in the figure (the left side). As an alternative to a hook and eye system, any other releasable attachment means can of course be used, such as a buckle, catch, clip, tie or other fastener.

(60) The fasteners 102, 103 are desirably adjustable so that a tight fit around the foot and leg can be achieved.

(61) Thus it is desired that tension can be adjusted around the foot and leg. Preferably tension can be adjusted at a plurality of locations (corresponding in this embodiment to the positions of the fasteners 102, 103.) This can assist in ensuring that the brace 100 is sufficiently tightly secured so as to substantially limit ankle movement. Adjustable fastening is also useful in being able to accommodate a range of different foot sizes/or shapes. Adjustable fastening can be achieved by providing sufficiently long lengths of Velcro or other hook and eye fastening material. (In other embodiments it can be done, by providing appropriately spaced holes in a strap that a buckle can engage, by providing a clip, clamp, catch or tie that can be used for adjustment of tension, etc.)

(62) Although in this figure two adjustable fasteners 102, 103 are provided, it is possible to provide just one or to provide three or more. If a single fastener is used it should be sufficiently large/wide to ensure that movement of the ankle is restricted. If two or more fasteners 102, 103 are used, then the size can be reduced, because the number and positioning of fasteners can itself facilitate restriction of movement.

(63) In the embodiment illustrated in FIG. 1 it can be seen that the trainer 1 is a relatively open item of footwear, whereby parts of the feet including the toes and part of the heel can be seen. This can be useful if the user (e.g. via a mirror) wishes to view parts of a foot to see which are moving/flexed. This can also be useful if a coach is instructing the wearer of the item of footwear. It will therefore be appreciated that in some respects the item of footwear 1 resembles an open-toed sandal. This is useful for user compliance, because a user will normally be easily able to put it on/take it off, being familiar with sandals.

(64) As discussed earlier, three downwardly protruding elements 104 are shown on the underside 106 of the curved element 107. In this embodiment the elements 104 fit tightly into the apertures 201 and this keeps the upper 100 parts and lower parts 200 together during use via a tight fit. This is sometimes known as a press fit, a push fit, a friction fit or an interference fit. (In FIG. 1 the elements 104 and apertures 201 are simply shown schematically and therefore the tight fit is not seen.) The downwardly protruding elements 104 can be forced into the apertures 201 by the weight of a user, as shown in the figure.

(65) It can be seen from the figure that the brace 100 can be secured to the lower part in several different positions. The figure illustrates a generally central position in which the three downwardly protruding elements 104 fit into three central slots 201. However it is also possible for the brace 100 to be fitted to a more forward or more rearward location of the lower part 200. This is because there are appropriately positioned slots along most of the length of the lower part. This is useful in taking into account different foot sizes. It is also useful in taking into account different positions that it may be desired to adopt.

(66) Thus, for example, in FIG. 1 it can be seen that the balancing block 300 is located directly underneath the mid-point of the foot. In respect of some sports or activities (or in the opinions of some coaches) this may be considered the sweet spot, where it is desired to focus balance, as discussed earlier.

(67) However if the brace 100 is moved one slot 201 further forward, relative to the lower part 200, the balancing block 300 will then be located slightly closer the heel. In the embodiment shown it would then lie underneath a point that is about a third of the way along the length of the foot, when measured from the back of the heel (the preferred sweet spot for focussing balance of the present invention, as discussed earlier.)

(68) If the brace 100 is moved one slot further backwards relative to the lower part 200, the balancing block 300 will be located slightly closer to the toes in the case of the foot illustrated. This is less desirable than position shown in FIG. 1. However, if, for example, a larger foot than the foot shown is used with the trainer 1 then moving the brace 100 one slot forward relative to what is shown in FIG. 1 could be useful (e.g. in positioning the centre point of the foot over the balancing block 300). Different foot sizes corresponding to different users can therefore be accommodated.

(69) Of course once the members 104 have engaged the slots 201 it will be necessary to disengage them if it is desired to move the brace 100 to a different position along the platform 203

(70) When it is desired to disengage the brace 100 from the lower part 200 the user can hold the lower part 200 stationary (or press down on it) whilst lifting the foot upwards. This effectively pulls the brace 203 and lower part 200 apart. This can be conveniently done whilst the user is sitting down.

(71) Alternatively, the user may grip or press down on the back of the lower part 200 whilst attempting to lift the heel upwards, but keeping his/her toes in a fixed position. This pivoting motion that can gradually release the members 104 from the slots 201, with the member 104 that is closest to the back of the heel of the user being released first.

(72) Other alternatives for disengagement include having a helper assistant pull the brace 100 and the lower part 200 apart (again preferably while the user is seated), by using a tool, (e.g. a lever or screwdriver), to prise them apart, etc. If a tool is provided this can advantageously be included in any of the kits of the present invention described earlier.

(73) Turning now to the lower parts of the trainer 1, it can be seen that the platform 203 is strengthened by a strengthening element 204. The strengthening element 204 provides increased rigidity. It extends across most of the length of the trainer apart from the region where the balancing block 300 is located.

(74) The balancing block 300 is located underneath the platform 203, as discussed earlier. It is releasably secured to a part of the base 202 by a screw or other releasable securing means (not shown). Thus it can be released and replaced with another balancing block 300 of a different size and/or shape if desired, to make balancing more difficult or easier.

(75) In FIG. 1 the balancing block shown 300 has a relatively large ground-contacting surface area 301.

(76) In order to increase the difficulty in balancing this balancing block 300 can be replaced with another one having a smaller ground-contacting surface area 301. Thus, for example, if (as here) the block 300 is generally cylindrical, other cylindrical blocks 300 with ground contacting surfaces of gradually reduced diameter can be provided.

(77) In the embodiment shown in FIG. 1 the main body of the balancing block 302 is formed of a relatively hard material (e.g. a hard plastics material) and the lowermost part 303 is formed of a material that is softer (e.g. a natural or synthetic rubber material), so as to reduce the risk of damage to a floor. The lowermost part 303 preferably comprises material that is scratch and/or slip resistant. It may have sloped or curved lower edges to aid in balancing/pivoting. This can help in protecting a floor and in balancing.

(78) A range of suitable balancing blocks are discussed in EP 2485617 in connection with the SKiA Sweetspot Trainer. These/similar balancing blocks can be used in the present invention. The exact shape is not crucial as long as the balancing block 302 can be used in training by a user to improve one or more balancing skills.

(79) Whichever balancing block 302 is used, the brace 100 in this example serves to substantially restrict the flexion and/or extension of a wearer of the training aid during balancing. It also acts to keep the shin of the wearer at a substantially fixed position relative to the platform 203 on which the brace 100 is mounted. As discussed in later examples, the brace 100 can be set at an angle, if desired, so that the shin is also forced to be at a given angle relative to the platform 203.

EXAMPLE 2

(80) Example 2 is similar to Example 1, apart from the fact that at least one of the downwardly projecting members 104 is provided with a release means 403. This is illustrated in FIG. 2.

(81) FIG. 2 provides a transverse cross section showing how a downwardly projecting element 104 with concave outer sides 401 fits into a slot 201. The slot 201 is located in an upper layer 202 of the platform 203. (FIG. 1 shows where the upper layer 202 is located.)

(82) It can be seen that the downwardly projecting element 104 is held in place in the slot 201 by convex inner side walls 402 of the base 201 fitting close to/against the concave outer sides 401 of the downwardly projecting element 104. The convex inner side walls 402 are complementary in shape to the concave outer sides of the downwardly projecting element 104.

(83) When it is desired to release the downwardly projecting element 104 from the slot 201, a wearer or a helper can press down on side levers 403. This forces the convex inner walls 402 away from the concave outer sides 401 of the downwardly projecting element 104. This allows the downwardly projecting element 104 to be lifted easily out of the slot 201. Typically this is done by the user simply lifting his/her foot upwards, given that (as illustrated schematically in FIG. 1) the downwardly projecting element 104 is a component of the brace 100 and the user will have the brace 100 releasably secured to his/her foot (e.g. by straps 102 and 103, as also illustrated in FIG. 1).

(84) The foregoing description explains how the downwardly projecting element 104 can be removed from the slot 201. Insertion of the downwardly projecting element 104 into the slot 201 can be achieved by the reverse action. Thus the levers 403 are pressed down so as to move the concave inner walls 402 slightly outwards and thereby to allow the downwardly projecting element 104 to be pushed down into position by the weight of a user wearing the brace 100.

(85) The levers 403 can be released once the element 104 has been pressed down far enough into the slot 201 so that the base of the downwardly projecting element 401 (i.e. the widest part) has moved past the narrowest part of the slot 201 (corresponding the bulges of the convex inner walls 402). It will then fit into position and will be releasably secured until it is desired to remove it.

EXAMPLE 3

(86) This example is illustrated by FIG. 3. FIG. 3 is similar to FIG. 2, apart from the side walls 401 of the downwardly projecting element 104 being straight rather than convex.

(87) In this embodiment the fit of the of the downwardly projecting element 104 into the slot 201 is an interference fit, because the convex inner walls 402 of the press against the straight sided walls 401 of the downwardly projecting element 104 to hold it in place. This is facilitated by the resilient deformability of the material from which the upper layer 202 of the platform 203 is formed. The downwardly projecting element 104 can be removed from the slot 201 when desired. In order to achieve release a wearer can press down on levers 403 and can lift his/her foot upwards with the brace 100 attached thereto.

(88) In both of the situations illustrated in FIGS. 2 and 3 and in the respective examples (Examples 2 and 3) release means are provided. It is provided here via levers 403, but any other facilitators of release can be used. (The release means will normally cause at least one component to move or change shape so that disengagement of engaging parts can occur.)

(89) It is not necessary to provide a plurality of release means. A single release means may be provided. Thus, for example, one downwardly protruding element 104 may be releasably secured in position so that it can be released by release means and the others may simply fits into slots 201 without needing/being provided with any particular release means. Furthermore, in some embodiments no particular release means need be provided.

EXAMPLE 4

(90) This example is illustrated by FIGS. 4 and 5, which, as explained earlier, provide side views of a further training aid 500 of the present invention. FIG. 4 shows this training aid 500 without a toe strap. FIG. 5 shows the training aid with a toe strap 501.

(91) The brace 507 includes a rigid strut 502. A heel receiving part 503 (the concave lower part) can be seen at the base of the strut 502. It has a slot 513 for receiving a strap (strap not shown). Towards the top of the strut 502 a lower leg receiving part 504 is located. This is also concave (the concave upper part) and is shaped here to fit around a rear part of the foot above the heel and below the calf. It can however be slid up or down the strut 502 to any desired position. It includes a slot 512 for receiving a strap (strap not shown). Once it has been slid to a desired position it can be retained there by friction. In an alternative embodiment it may be releasably secured to the strut by a releasable retaining means (not shown), such as a releasable clamp or catch.

(92) It will be appreciated that if the strut 502 is long enough, a similar arrangement could be used for a brace 507 that reaches the calf region. Here the concave upper part 504 may be large enough to engage the rear of the calf or a part thereof

(93) The angle of the strut 502 relative to the platform 506 may also be set slightly differently to allow for the fact that a calf bulges.

(94) The brace 507 acts to keep the shin of a wearer at a substantially fixed position (here an angled position) relative to the platform 506 on which the brace 507 is mounted. The brace 507 also acts as a restrictor for substantially restricting flexion and/or extension of an ankle of a wearer.

(95) In the embodiment shown there is releasable securing element (here a catch 508) that releasably secures the brace 507 to the platform 506. Such a catch 508 is provided on each side of the platform 506. (Only one can be seen in the side view shown.) When the catches 508 are released the brace 507 can moved to another desired position along the platform 506 (e.g. for a user with a different foot size). When it is at the desired position it can then again be releasably secured relative to the platform 506 by engaging the catches 508.

(96) If desired, the brace 507 may be mounted on a rail (not shown) or may be otherwise slidably mounted so that it can be slid along the platform 506 when the catches are released. Alternatively it may simply be lifted off the platform 506 after being released and then put down again at a new desired position along the platform 506 before being releasably secured.

EXAMPLE 5

(97) This example is in respect of a crude working model that has some similarities with the training aid illustrated schematically in FIGS. 4 and 5.

(98) This working model 600 is illustrated in FIGS. 6 and 7, being shown from different sides in these figures.

(99) Here a rigid strut 601 is provided (e.g. a metal strut) that is secured to a concave receiving element 602 that is shaped to receive a calf of the wearer. This calf receiving element is formed of resilient plastics material. It has a slot 603 in each side that receives a strap 604. The strap 604 is shown fastened tightly so that concave receiving element 602 is secure around a user's calf.

(100) It can also be seen from the figure that a metal heel block 606 is provided. This has rigid side walls and a rigid rear wall, with a slot being 607 provided in each side wall for receiving a strap 608. This strap 608 is fastened over the foot of a user and prevents the foot moving forwards. The rear wall of the heel block 606 prevents the foot moving backwards. (If necessary, padding 609 can be provided as shown. This can be useful if the foot is relatively small and/or, if, as here, the heel block 606 is uncomfortable in the absence of padding.)

(101) The two fastening straps 604, 608 secure the foot and lower leg in position in the brace 612.

(102) The heel block 606 is slightly wider at the bottom that at the top. This is because it has two inner horizontal channels that receive the sides of the platform 610 and thereby allow the block to be 606 slid along the platform 610, once securing screws 611 (which normally hold it in a desired position) have been released.

(103) Thus, once the securing screws 611 are released, the brace 612 can be slid along the platform 610 until a desired position is reached. The screws 611 are then screwed into the sides of the platform 610 to releasably secure the heel block 606 in place at the new position along the platform 610. The new position may for example be one that is desirable for a different foot size, a different balancing action, different weight distribution, etc.

(104) In this embodiment the screws 611 screw into the material of the platform 610. It is however possible for complementary bores for receiving screws to be provided in the platform walls so that the material of the platform is not affected by screwing into it. These bores may be spaced at a number of regular intervals along the side of the platform 610 so as to take into account a corresponding number of positions where the brace 612 can be moved to. They are preferably reinforced, e.g. with a metal or plastics surround.

(105) A spacer 613 is provided that has a sloping rear surface 614. The spacer 613 is located between the heel block 606 and the strut 601 and is secured to both of these (e.g. by screws or by a strong adhesive). The angled rear wall 614 of the spacer 613 causes the strut 601 to be set at a desired angle. (A different spacer with a rear wall at a different angle can of course be used if it is desired to provide a different angle at which the strut is set relative to the platform 610.) This in turn forces the shin of a wearer of the training aid to adopt a corresponding angle. (The angle between the platform and the shin is illustrated on the figure.) By keeping the shin at a relatively fixed position and securing the foot and leg in position by straps as illustrated (or other retaining means) ankle torsion and/or flexion is restricted.

(106) A balancing block 615 is also shown that is releasably secured to the underside of the platform 610.

EXAMPLE 6

(107) This is illustrated by FIG. 8 9 and is an alternative arrangement to that described in Example 50. Here the brace 700 has a generally unitary structure rather than having a part that engages the heel and a different part that engages a higher part of the back of the leg.

(108) It can be seen that the brace 700 has an upright back wall 701. This restricts movement of the calf of the wearer and the back of the heel of the wearer. Sloping side walls 702 are also provided. These are wider at the base than at the top. This helps provide rigidity, whilst also restricting foot movement.

(109) As for Example 5, screws 711 are provided that can be released to allow the brace 700 to be slid along the platform 710 to a new position. The screws 711 can then be screwed into the sides of the platform 710 to releasably secure the brace 700 in a new position relative to the platform 710. (Again, as discussed earlier, complementary bores may be provided for receiving the screws, if desired.) It should be appreciated that the brace 700 shown here is a relatively crude one and is simply a working example of a brace having a unitary structure.

(110) Upper 712 and lower 713 straps help secure the brace 700 in place relative to lower leg of a user. A brace that is shaped to fit more snugly against the contours of the lower leg art of the leg could of course be provided instead and could also still provide a unitary structure. It could, for example, be made by casting, moulding, by three dimensional printing, etc.

EXAMPLE 7

(111) This embodiment is not illustrated by additional figures, but is the same as that illustrated in FIG. 6, apart from the brace being used to brace the user's foot whilst the foot is inside a shoe (not shown).

(112) If required, the brace and/or platform shown in FIG. 6 could be made wider and/or longer to allow for the dimensions of a shoe, although this is not needed for the working model shown in FIG. 6, given that the brace and platform are already quite large.

(113) The straps shown in FIG. 6 can of course also be made longer and/or positioned slightly differently, if this is needed to accommodate a shoe, although this is again not needed with the working model shown in FIG. 6. Thus in this example the brace will restrict undesired movement of a user's foot within the shoe. In particular, the brace will still act as a restrictor for substantially restricting flexion and/or extension of the ankle of a wearer within the shoe. As with the other examples, the user's shin is kept at a substantially fixed position relative to the foot and platform when the user is balancing or attempting to balance.

EXAMPLE 8

(114) This embodiment is illustrated by FIG. 9. It is very similar to that shown in FIG. 8, but with the unitary brace structure 700 essentially turned through 180 and a large aperture provided through it in the form of an arch 714 that allows the front of a foot to be inserted through it. (This is not needed in Example 8.)

(115) Here the shin region of the front of the leg is close to a front wall 717 of the brace 700, the front wall being located in front of the shin. During use, the shin presses against the front wall 717, either directly or through intermediate cushioning (here a foam insert 716),

(116) Straps 712, 713 are again provided through apertures in the brace 700. Thus the brace 700 is again strapped tightly against both a user's lower leg (via the top strap 712) and foot (via the lower strap 713).

(117) The embodiment illustrated here is more preferred than that described in Example 6. Although both embodiments were found to work as training aids, the user found it easier to use the training aid when the rigid part of the brace 700 was in front of the lower leg rather than behind it. Thus the front brace was found be preferred to the rear brace.

(118) FIG. 10 is also useful for comparison. It shows the embodiments described in Example 7 and the present example (and shown in FIGS. 8 and 9 respectively) side by side. In FIG. 10 the Example 7 embodiment (having a rear brace 700, as shown in FIG. 8) is worn on the right foot and the Example 8 embodiment (having a front brace 700. as shown in FIG. 9) is worn on the left foot. (FIG. 11 is similar to FIG. 10, but is a rear view.)

(119) It was again confirmed by the user that the front brace 700 was easier to use and gave better performance than the rear brace, although both functioned sufficiently well to provide confidence in proceeding further with the invention. It should be recalled that this example simply illustrates a crude working prototype. Thus, a more comfortable brace that is shaped to fit more snugly against the contours of the one or more parts of the lower leg could be provided instead.

EXAMPLE 9

(120) This is the same as the embodiments described in Example 8, apart from the brace being used to brace the user's foot whilst the foot is still inside a shoe (not shown). Here the front of the shoe with the user's foot inside it would protrude through the arch 714. (Of course dimensions of components can be changed if this is necessary to accommodate a shoe.)

(121) As with the other examples, the shin of the user would also be kept at a substantially fixed position relative to the foot and platform when the user is balancing or attempting to balance.

(122) The brace would also still act as a restrictor for substantially restricting flexion and/or extension of the ankle of a wearer within the shoe.

EXAMPLE 10

(123) This example is illustrated by FIGS. 12 to 17, which show a version of the training aid 820 in which the angle of a brace 800 relative to the platform 811 can be adjusted.

(124) The location of a balancing block 814 underneath the platform 811 can also be adjusted, so that it can be positioned at several spaced apart locations. (This can be useful for various sports or activities, as discussed later.)

(125) It can be seen that, unlike earlier examples, the training aid 820 comprises two vertical plates 801, 802 that are connected together by a releasable nut and bolt 803. The plates 801, 802 are roughly triangular in shape although this is not essential. The shape can vary significantly, as long as the plates can perform their function.

(126) The upper plate 801 includes a plurality of spaced apertures 804. Here the apertures are spaced along an arc (see e.g. FIG. 13). In contrast, the lower plate 802 has only a single aperture 804.

(127) The upper plate 801 is shown abutting to a rigid shin guard 806. The lower plate 802 is above a rigid arch 807 into which a foot can be inserted. The arch 807 can be considered in some respects as a large foot strap that limits foot movement, although it does not tighten like a strap.

(128) In the embodiment illustrated the brace 800 is secured by two straps 808, 809 around the lower leg. One strap 808 passes through an aperture between upper plate 801 and the shin guard 806. The other strap 809 passes over a tongue 810 that extends from the top of the arch 807 towards the shin guard 806.

(129) Given that the arch 807 and shin guard 806 are each quite strong and resilient and that each of these is also connected to one of the rigid plates 801, 802, the front face of the shin guard 806 is effectively locked in position at a given angle relative to the vertical (or to the platform 811) when the plates 801, 802 are secured to one another by the nut and bolt 803. This therefore causes the shin to adopt a corresponding angle during balancing.

(130) As discussed above, the foot is restricted by the arch 807 into which it is inserted and the platform on which it rests. The straps 808, 809 also help prevent any undesired movement.

(131) Thus the brace 800 still acts as a restrictor for substantially restricting flexion and/or extension of the ankle during balancing.

(132) In some sports/activities it is desirable for a user to practice balancing not only when in a relatively upright position, but also when a user is leaning, crouching, etc. In particular, it can be desirable for a user to practice leaning forwards or backwards at a given angle to the vertical. In the case of skiing, for example, it may be desired to lean forwards with a user's shin at one or more angles that correspond to angles at which it would be when in a ski boot set on a ski. Thus it can be useful to be able to adjust the angle between the front of the shin and the vertical.

(133) In the embodiment illustrated by this example, this can be done by removing the nut and bolt 803 and then moving the upper plate 801 relative to the lower plate 802 until a desired aperture of the upper plate 801 is aligned horizontally with the single aperture of the lower plate 802. The bolt 803 can then be passed through both apertures and secured by tightening a nut.

(134) If the plates 801, 802 are secured together using the lowermost aperture of the upper plate 801 then in this embodiment the angle at which the front face of shin pad 806 is set will be at or close to vertical. This also means that the shin will be forced to adopt a corresponding angle. Alternatively, if the plates 801, 802 are secured together using the uppermost aperture of the upper plate then the angle the front of the shin pad 806 adopts will be relatively far from the vertical and the shin a wearer of the brace 800 will be at a corresponding angle.

(135) FIG. 13 illustrates a situation where the angle of the front of the shin pad is set at 22 degrees from the vertical (i.e. 68 degrees from the horizontal platform 811). FIG. 14 illustrates a situation where said angle is almost vertical (i.e. 2 degrees from the vertical and 88 degrees from the horizontal platform 811).

(136) Angles between these values can be set by using different apertures 804 for locking plates 801 and 802 together. Thus a range of angles can be provided that encompass angles (sometimes known as ski boot angles) that a skier may wish to practice adopting when balancing.

(137) Other ranges of angles can of course be provided with other training aids and the above range is not limiting. In some situations if the angle from the vertical is increased (so that the shin of a wearer of the brace is angled further forwards) it may also be desired to move the balancing block 812 further forwards relative to the brace 800. This can be seen by comparing FIGS. 15 and 16, as discussed below.

(138) In FIG. 15 it can be seen that the balancing block 812 is relatively central. The set angle for the shin pad 806 is 2 degrees from the vertical (88 degrees from the horizontal). In FIG. 16 the balancing block 812 is in a much more forward position. The set angle for the shin pad is 18 degrees from the vertical (62 degrees from the horizontal).

(139) It should be appreciated that the balancing block 812 can be screwed into position at various spaced intervals along the platform 811. This is illustrated by FIG. 17. Here it can be seen that a pair of screws 805 is used to releasably secure a balancing block 812 (not visible in this figure) in position.

(140) The pair of screws 805 have been screwed into the balancing block 812 through the front pair of a series of paired apertures 813. (The figure shows the location of the screws 805 for securing a balancing block 812 in the forwards position shown in FIG. 16. The screws would pass through a pair of apertures 813 further back for securing a balancing block 812 in the position shown in FIG. 15.)

(141) Thus a balancing block 812 can be releasably secured at a plurality of different locations along the underside of the platform 811.

(142) It should be appreciated that, as an alternative (or additional) option, it is possible to have the brace moveably mounted relative to the platform (e.g. as discussed in earlier examples). Thus, in some embodiments, the brace and balancing block can be moved relative to one another along the platform.

EXAMPLE 11

(143) A different example of an item of footwear 900 that can be used as a balancing trainer of the present invention is shown in FIG. 18. It includes a platform 902 and a releasable foot securer 904 for releasably securing the front part of a user's foot to the platform during balancing.

(144) The releasable foot securer 904 comprises two foot straps 906 and 908. Each strap 906, 908 is secured to the platform 902 by a platform fixing 924. The straps 906, 908 are releasably held together when the item of footwear is being worn by a hook and loop fastener system, e.g. Velcro (not shown).

(145) A user can pull the straps 906, 908 apart when it is desired to release them, so as to also release the user's foot (also not shown). However, during use the hook and loop fastener system is strong enough to keep the straps 906, 908 together.

(146) The item of footwear 900 also comprises a lower leg engager in the form of a brace 910. It can be seen that the brace 910 comprises a front part 912 and a rear part 914, with the brace 910 being in a closed position around the lower part of a user's leg (not shown) when secured by a releasable brace securer 916.

(147) The releasable brace securer 916 comprises two brace straps 918 and 920. As for the foot straps 906, 908 described earlier, the brace straps 918, 920 are held together by a hook and loop fastener system and can be pulled apart by a user when it is desired to separate the straps 918, 920. Each strap 918, 920 is secured to the brace 910 by a side fixing 922

(148) As can be seen from FIG. 19, when the brace strap 916 is open, the front part 918 can be pivoted forwards about pivot 922, whilst the rear part 920 stays in a fixed, upright position. This allows a user to place a foot within the brace 910 or to remove it from the brace 910.

(149) In this example the brace 910 is formed of a rigid resilient material. It is connected to the platform via shoulders 926. If desired, the shoulders 926 and a lower part of the brace 910 may be integrally moulded together with the platform 902 so as to provide a unitary structure. Alternatively an adhesive or other fixing means (e.g. rivets, screws, or a click fit, snap fit or interference fit system) may be used fix the brace 910 to the platform 902.

(150) The brace 910 substantially restricts lateral movement of the lower part of the leg. This is useful in reducing the risk of injury.

(151) A balancing member 928 in the form of a balancing block can be seen located underneath the platform 902 in FIGS. 18 and 19. The balancing member 928 can also be seen in FIGS. 20 to 22. It has a non-slip ground contacting layer 930 formed for example from a synthetic rubber material. Ridges 938 are also provided that further reduce the risk of the balancing member 928 slipping. The remainder of the balancing member 928 is formed of a hard material 932 (e.g. a hard plastics material).

(152) It can be seen from FIG. 20 that a balancing member 928 is fixed to a mounting plate 934 and the mounting plate 934 is releasably secured to the platform by screws 936. These screws 936 fit into corresponding screw-receiving apertures in the underside of the platform 902 (not shown). When the screws 936 are unscrewed, the mounting plate 934 and associated balancing member 928 can be removed. It can then be replaced with another mounting plate 934 and associated balancing member 928.

(153) FIG. 21 shows another mounting plate 934 having been screwed into position via the same screws 936 as those used in FIG. 20. Here it can be seen that the balancing member 928 shown is of the same length as the one shown in FIG. 20, but is of a narrower width. This allows a user to focus balancing skills on a narrower ground contacting area.

(154) Once the user has become accomplished at balancing on the balancing member illustrated in FIG. 21 the mounting plate 134 and the associated balancing member 928 can also be removed and can then be replaced with a still narrower balancing member 928 and associated mounting plate 134. The still narrower balancing member 928 is illustrated in FIG. 22. Again the same screws 136 can be used, because the mounting plate 934 has the same shape, with the screw holes being positioned at the same locations.

(155) It should be noted that a user can revert from a relatively narrow to a relatively wide balancing member 928 if it turns out that the user is losing confidence or needs further practice on a relatively wide balancing member. Thus, for example a user practising on the balancing member 928 shown in FIG. 22 and finding it too difficult to balance on this, or losing confidence, may decide to replace it and the associated mounting plate 934 with the balancing member 928 and associated mounting plate 934 shown in FIG. 21 (or in FIG. 20) until the user has improved confidence and/or improved balancing skills.

(156) The user may then revert again to the balancing member 928 and associated mounting plate 934 shown in FIG. 22.

(157) FIGS. 18 to 22 illustrate a left item of footwear. In practice, a user will of course wear left and right hand items of footwear on his/her left and right feet respectively and will have a corresponding balancing member 928 and associated mounting plate 934 underneath the sole 902 of each foot.

(158) The user can perform any desired balancing exercise, but it is preferred that the user attempts to balance whilst moving forwards or backwards and placing one foot in front of the other. If desired, the user may attempt to follow a marked line, track or other indicator.

(159) Thus, for example, in the case of tightrope walking training, a user may attempt to follow a line the thickness of a tightrope on the floor or a floor covering. The balancing exercises may of course be varied depending on what a user is practising to do.

(160) For example a user practising for moving along a gymnastic beam quickly may decide to step quickly with one foot placed in front of the other (e.g. whilst attempting to follow a marked line, track or other indicator).

(161) In the case of training for tightrope walking, the user will normally step slowly and may even use an aid (e.g. a balancing pole held by the user as is often done whilst tightrope walking).

(162) Whatever sport or activity the user is training for, the invention allows the user to focus balancing on an increasingly narrow area. The balancing members can easily be removed and replaced using a screw-driver. Alternatively, if a screw head is shaped for receiving an Allen key rather than a screwdriver, this can be used instead.

(163) It is of course also possible not to use one or more screws and to use other releasable attachment means instead, e.g. one or more releasable clips, catches, etc., provided that the releasable attachment means allows the balancing member to be maintained in position during use, until it is desired to remove it.

EXAMPLE 12

(164) This example is the same as Example 11, apart from the fact that no mounting plate is used and the screws 936 are screwed through the balancing member 928 itself, as illustrated in FIG. 23.

(165) Here it can be seen that the screws 936 are countersunk a little so as not to protrude from the balancing member 928. This helps to prevent screw heads from interfering with balancing. It also helps prevent/reduce the risk of damage to a floor or other ground surface.

EXAMPLE 13

(166) Here a brace 940 is provided (see FIG. 24) that is different from the one used for Examples 11 and 12.

(167) It comprises an upper 942 formed of leather or of another strong fabric material. It again functions to restrict lateral movement of part of the lower leg. It also helps restrict ankle flexion and/or extension.

(168) The upper 942 is fixed to the platform 902. This can be achieved by stitching, adhesive or any other suitable fixing means. The upper 942 may optionally be reinforced by a strut or another reinforcing member (not shown). This can help increase rigidity. For example a region at the back of the lower leg may be reinforced (e.g. with a strut or support). Any suitable resilient material can be used for reinforcement, e.g. a plastics material, a metal or metal alloy material, a composite material, wood, etc.

(169) Here the upper 942 is shown as being open-toed and also as having an open heel portion. Thus it resembles the upper of certain sandals. This is not however essential and the upper 942 may enclose the heel and/or toes.

(170) Laces 944 are shown that are about to be tied. However straps, catches or any other releasable securing means can of course be used as an alternative.

(171) In this embodiment the upper 942 releasably secures both the user's foot and the user's leg in position relative to the platform. Thus, unlike FIGS. 14 and 15, there is no need for additional strapping over the foot.

(172) A balancing member 928 is provided that is the same as the one shown in FIG. 19. Thus it has a non-slip ground contacting layer 930 comprising a plurality of ridges 938. The remainder of the balancing member 928 is formed of a relatively hard material 932. The balancing member 928 is attached to the base of the platform 902 by screws (not visible in this figure but corresponding to the screws 936 shown in FIG. 19). Thus the balancing member 928 can be removed by unscrewing it from the underside of the platform and then screwing in another balancing member 928 of a different width.

(173) As discussed earlier, it is preferred in some embodiments that, as training progresses, narrower balancing members 928 are used. The length of the balancing members 928 is preferably the same.

EXAMPLE 14

(174) This is as for any preceding example, apart from the fact that the item of footwear is large enough to be used by a user who is already wearing a shoe or another item of footwear. Thus a platform, brace, straps, etc., can be shaped accordingly so that a foot of a user wearing the item of footwear can be accommodated and the user can practice balancing in accordance with a method of the present invention.

EXAMPLE 15

(175) This example illustrates an intended production model of an item of training footwear 1001 (also known as a trainer) of the present invention. It is illustrated by FIGS. 25 to 38 and by FIGS. 41 to 52.

(176) The trainer 1001 is used to balance or attempt to balance on a ground-contacting surface of a balancing block (described later). It includes a platform 1000 on which a foot of a user stands whilst the user is balancing or attempting to balance. Thus this platform 1000 is sometimes also referred to herein as the standing platform 1000.

(177) The trainer 1001 includes a brace 1011. The brace 1011 includes struts 1002, 1003, which are operably connected to side supports 1006, 1008 and can be pivoted relative to the side supports about a pivot 1004, along which there is an axis of pivoting.

(178) Starting with FIGS. 25 to 27, these show alternative views of a trainer 1001 comprising a standing platform 1000 and a single balancing block 1020 releasably secured underneath the platform 1000.

(179) The trainer 1001 shown here can be used for training a user in adopting a correct position during skiing, skating, surfing, and other sports and activities that benefit from accurate fore-aft balance.

(180) The standing platform 1000 in this embodiment has an upper surface that is at a small angle to the horizontal (here an angle that is at, or about 3 degrees to the horizontal), when the user is correctly balanced on a flat, generally horizontal ground surface (e.g. a level floor). Thus, if the balancing block 1020 has a generally flat underside 1021, when this is flat against a generally horizontal ground surface ground surface, the upper surface of the platform 1000 will be at said small angle to the horizontal.

(181) A front strap 1030 holds the front of a user's foot in place. It can be tightened or loosened by an adjustable fastener 1031 (e.g. via a releasable hook and eye system, such as a Velcro system).

(182) The side supports 1006, 1008 are fitted towards the rear of the standing platform 1000. They are positioned to lie adjacent a user's ankle. Indeed it is preferred that the aforesaid axis of pivoting through pivot 1004 passes through or proximal to the effective centre of flexion and extension of the ankle joint.

(183) Both a left foot and a right foot version of the trainer 1001 will of course normally provided. The invention therefore includes a pair of trainers.

(184) One of the side supports (in these figures the side support 1008) is located slightly more forwards along the platform than the other one (than side support 1006). This takes account of the normal structure and anatomical function of the ankle. The more forwardly located side support 1008 can be referred to here as the medial ankle support and the more rearwardly located support 1006 can be referred to as the lateral ankle support (to correspond with the ankle regions that these supports are closest to).

(185) The side supports 1006, 1008 are lined with padding 1007, 1009 to provide comfort and support.

(186) The rigid struts 1002 and 1003 are operably linked to the side supports 1006, 1008 at pivot point 1004. As discussed earlier a screw is present at each pivot point and the screws can be loosened to allow pivoting or tightened when no further pivoting is desired (i.e. when a desired angle of the brace 1011 relative to the platform 1011 has been set).

(187) An anterior shin pad 1040 connects the two struts 1002, 1003. The shin pad 1040 is also lined with padding 1041 to ensure comfort and support. At the rear, two releasable ratchet straps 1032, 1034 with support pads 1036, 1038 connect the two struts 1002, 1003, and can be tightened to ensure a snug/tight fit, or can be loosened when the user wants to remove the trainer 1001.

(188) The side supports 1006, 1006 include arcuately arranged teeth 1012 marked in degrees from the vertical. They can be engaged with complementary teeth 1014 by operating a lever 1010 located on each strut 1002, 1003 below the pivot point. The struts 1002, 1003 are then locked in a desired position (i.e. at a desired angle relative to the platform 1000).

(189) When the lever 1010 is released then the teeth 1012, 1014 become disengaged from and pivoting of the struts 1002, 1003 about the pivot 1004 can occur until another desired angle of the struts 1002, 1003 relative to the platform has been reached. The lever 1010 can then be operated again to lock the struts 1002, 1003 in position until it is desired to release them.

(190) In FIGS. 25 to 27 the rigid struts 1002 and 1003 have been set at a right angle to the standing platform 1000. Here an angle of 0 degrees is indicated (which indicates a perpendicular orientation relative to the platform 1000.).

(191) The underside of the trainer has three alternative positions at which the balancing block 1020 may be located during use. There is a rearwards position 1050, a central position 1052 (obscured in certain views, where the block is already fitted in this position) and a forwards position 1054. There are also four positions for fitting balancing blocks during storage, i.e. positions 1060, 1062, 1064 and 1066. It can also be seen that there is central ridge that has a front part 1072 and a rear part 1070 (sometimes referred to herein as the front ridge 1072 and rear ridge 1070 respectively, although they are part of the same ridge). This adds to strength and rigidity.

(192) FIG. 28 is similar to FIG. 27, but the balancing bock 1008 of FIG. 27 has been replaced in FIG. 28 with one 1028 that is of the same width, but is not as long. The brace 1002 has been set here at a smaller (more acute) angle relative to the standing platform 1000 than in FIG. 27. Thus it is no longer perpendicular to the platform 1000.

(193) FIG. 29 is similar to FIG. 27, but the balancing block 1020 is in the most forwards fitting position 1054. FIG. 29 also illustrates the maximum extent the rear of the platform 1000 can tip downwards with the block 1020 in this position until the rear strengthening ridge 1070 comes into contact with a level floor surface. When such contact occurs this acts as a stop that helps prevent accidents/reduce the risk of the rear of the platform 1000 user tipping backwards to an undesired extent. This can therefore increase stability/confidence of a user and reduce the risk of falls.

(194) FIG. 30 is similar to FIG. 29, but here the balancing block 1020 has been fitted in the most rearwards fitting position 1050. This figure also illustrates the maximum degree that the front of the platform 1000 can tip downwards with the block 1020 in this position 1050 before the front strengthening ridge 1072 comes into contact with a floor surface. When such contact is achieved this again acts as a stop. Thus it helps prevent/reduce the risk of the front of the platform 1000 tipping downwards to an undesired extent.

(195) FIG. 31 shows the standing platform 1000 fitted with a stack of 4 balancing blocks 1080, 1082, 1084, 1086 releasably secured underneath it. The balancing blocks 1080, 1082, 1084, 1086 are each longer than they are wide. In this figure the teeth 1012, and 1014 have been disengaged from one another by use of lever 1010 and the rigid struts 1002, 1003 have been pivoted rearwards on pivot 1004 to an angle of approximately 45 degrees.

(196) FIG. 32 shows the standing platform 1000 fitted with a stack of 2 balancing blocks 1080, 1082 releasably secured underneath it that are both longer than they are wide. In this figure the teeth 1012, and 1014 have been disengaged from one another by use of lever 1010. This allows the rigid struts 1002, 1003 to freely pivot, to allow free movement of the ankle (for example to allow walking). In this figure they are pivoted forwards to an angle of approximately 45 degrees.

(197) FIG. 33 shows the underside of standing platform 1000, with balancing block 1080 having a soft rubber-patterned underside 1081 fitted in position, Because this is much longer than the balancing block shown in FIGS. 25 and 26 it is fitted over all three of the positions referred to earlier as the rearwards, central and forwards positions 1050, 1052 and 1054. Balancing block 1080 is therefore substantially longer than it is wide. The underside of the balancing block 1080 has 4 fitting holes 1090, 1092, 1094, 1096 to receive further blocks. Thus a stack of balancing blocks can be formed and secured in position.

(198) FIG. 34 is similar to FIG. 33, but with another balancing block 1082 attached to the underside 1081 of block 1080 by using fitting holes 1090, 1092, 1094, 1096. The block 1082 has a soft rubber-patterned underside 1083, which is narrower than the underside 1081 of block 1080. The underside of the additional block 1082 has 4 further fitting holes 1091, 1093, 1095, 1097.

(199) FIG. 35 is similar to FIG. 34, but with a further balancing block 1084 attached to the underside 1083 of block 1082 using fitting holes 1091, 1093, 1095, 1097. The further block 1084 has a soft rubber-patterned underside 1085, which is narrower than the underside 1083 of block 1082>

(200) FIG. 36 is similar to FIG. 35, with a still further balancing block 1086 attached to the underside 1085 of block 1084. The block 1086 has a soft rubber-patterned underside 1087, which is narrower than the underside 1085 of block 1084

(201) FIG. 37, this shows side supports 1006, 1008 attached to the rear of the standing plate 1000, but with the remainder of the brace removed. A bore 1005 that receives a screw and through which an axis of pivoting passes (when the device is in use) is also shown.

(202) FIG. 38 shows a view of the underside of the standing platform 1000. The central and front fitting points 1052 and 1054 for balancing blocks are shown (with the rear fitting point being obscured by a balancing block in position). The four storage points 1060, 1062, 1064 and 1066 are also shown, as are ratchet clips 1033, 1035 for releasable ratchet straps 1032, 1034.

(203) Various embodiments within the scope of Example 15 will now be described with reference to the associated figures:

EMBODIMENT 1

(204) FIGS. 41 to 44 show balancing blocks attached to the rear fitting position 1050 (i.e. behind central and front fitting positions 1052 and 1054). Rigid struts 1002, 1003 shown in these figures are fixed in a vertical position relative to the standing plate 1000, using interlocking teeth 1012, 1014 that are releasably locked in position.

(205) FIG. 41 shows a balancing block 1020 fitted to the rear fitting position 1050.

(206) FIG. 42 shows a smaller balancing block 1022 fitted to the rear fitting position 1050.

(207) FIG. 43 shows an even smaller balancing block 1024 fitted to the rear fitting position 1050.

(208) FIG. 44 shows a still smaller balancing block 1026 fitted to rear fitting position 1050.

(209) The undersides 1012, 1023, 1025 and 1027 of balancing blocks 1020, 1022, 1024 and 1026

(210) respectively are rubberised in order to reduce the risk of slipping and/or damaging a floor.

(211) As a result of the positioning of the rigid struts 1002, 1003 a user using a device as shown in FIGS. 41 to 44 will be required to stand in a relatively upright posture. The centre of the balancing blocks in the rear fitting position corresponds closely to anatomical centre (that is, the centre of fore-aft balance for an individual standing in a relatively upright posture), regardless of foot size.

(212) Therefore, when used in this embodiment, this combination of settings allows users to experience an accurate simulation of being centrally balanced when standing. This is relevant for activities such as golf relaxation training, singing, voice training, and rehabilitation from injury.

EMBODIMENT 2

(213) FIGS. 45 to 49 show balancing blocks attached to the central fitting position 1052, between rear and front fitting positions 1050 and 1054. The rigid struts 1002 and 1003 in these figures is fixed at an angle of approximately 12 degrees from vertical, using the interlocking teeth 1012, 1014.

(214) FIG. 45 shows a balancing block 1020 fitted to central fitting position 1052.

(215) FIG. 46 shows a smaller balancing block 1022 fitted to central fitting position 1052.

(216) FIG. 47 shows an even smaller balancing block 1024 fitted to central fitting position 1052.

(217) FIG. 48 shows an even smaller balancing block 1026 fitted to central fitting position 1052

(218) The location of the central fitting position 1052 is designed to ensure that the balancing block lies directly underneath the centre of the foot of a user, when the brace is set at an angle of approximately 12 degrees from vertical, regardless of foot size. This combination of settings allows users to experience an accurate simulation of being centrally balanced on skis or skates. It also allows users to practice the dynamically-centred fore-aft balance skills required for sports such as skiing, ice-skating, roller-skating, in-line skating and surfing.

EMBODIMENT 3

(219) FIGS. 49 to 52 show balancing blocks attached to the front fitting position 1054, i.e. forward of the rear and central fitting positions 1050 and 1052.

(220) The rigid struts 1002, 1003 in these figures are fixed in a flexed position relative to the stank plate, at about 21 degrees from vertical, using the interlocking teeth 1012, 1014.

(221) FIG. 49 shows balancing block 1020 fitted to the front fitting position 1054.

(222) FIG. 50 shows a smaller balancing block 1022 fitted to the front fitting position 1054.

(223) FIG. 51 shows an even smaller balancing block 1024 fitted to the front fitting position 1054.

(224) FIG. 52 shows a still smaller balancing block 1026 fitted to the front fitting position 1054.

(225) The location of the central fitting position 1054 is designed to ensure that the balancing block lies under the ball of the foot of a user, when the brace is set at an angle of approximately 21 degrees from vertical, regardless of foot size. This combination of settings allows users to experience an accurate simulation of being balanced on the ball of the foot and to practice the dynamic fore-aft balance skills required for sports such as horse riding and MTB cycling.

EXAMPLE 16

(226) This example is illustrated by FIGS. 39 and 40. It concerns an alternative trainer 1100 to the trainers discussed in Example 15. In Example 16 the trainer has a brace 1101 that allows some free flexion and extension of the ankle for walking movements, while still providing lateral stability for the ankle joint. The brace 1101 does not include any struts. It can be attached to the standing platform 1000 that is shown on FIG. 39. (The platform 1000 shown in FIG. 39 corresponds to the platform for the embodiments discussed in Example 15, but with the brace and side supports removed. Thus the platform 1000 can be used for various examples and embodiments.)

(227) The front foot strap 1030 and the fastener 1031 shown in FIG. 40 are the same as those shown in FIG. 39. However balancing blocks 1080, 1082, 1084, 1086 have been fitted to the underside of the standing platform 1000 and a brace 1101 has been attached to the top of the platform 1000 using releasable fasteners 1102. The brace 1101 is fitted around the foot by using a hook and eye system (e.g. a Velcro system) provided on straps 1104 and 1106.

GLOSSARY

(228) Some terms that are used herein are discussed in further detail below:

(229) Brace

(230) This term is used to describe a device for fitting around or against at least a part of a lower foot and/or leg that is not a shoe. It holds at least part of a wearer's foot and/or leg in a desired position so that movement of said at least part is substantially restricted. The brace is not part of a separate shoe (or boot).

(231) It is therefore different, for example, from a rigid ski boot where the boot itself holds a user's lower leg in a desired position and there is no separate brace.

(232) In the context of the present invention the brace functions to hold at least part of user's foot or leg in a desired position for balancing or attempting to balance on a balancing block (or a stack of balancing blocks). This can be while the user is walking or otherwise traversing over ground (e.g. when training in tightrope walking) or while the user stays in a given location whilst balancing or attempting to balance

(233) The brace may include one or more elongate rigid and/or resilient components (e.g. struts). It is not however essential that these are present.

(234) In some embodiments the brace allows sufficient flexion and/or extension of the ankle for walking or for other actions where during training a user uses the footwear to traverse ground. In other embodiments the brace may serve to prevent or substantially restrict flexion and/or extension of the ankle. In any event it is desired that the brace substantially restricts lateral movement of the foot relative to the platform.

(235) Shoe

(236) The term shoe as used herein includes sports shoes, work shoes, leisure shoes, slippers, sandals, boots or any other supporting footwear used for walking on or carrying out an activity. The brace may be used to brace a user's foot when the user is barefoot or, in certain embodiments when the user is wearing a shoe.

(237) Training

(238) This means practising a skill or activity. In the context of the present invention it will generally involve repeating a balancing procedure to try to obtain an improvement. It does not require success/immediate success. One or more failures in balancing/practising balancing will be entirely usual.

(239) It is envisaged that most users will be able to improve their balancing skills by correct use of trainers of the present invention. They may for example be balance for a longer period and/or focus balancing over a smaller area and/or improve balancing posture and/or improve weight distribution, etc.
