[0031] FIG. 7 is a top view of the anti-pronation element of the article of footwear of FIG. 3.

[0032] In the drawings, like parts are denoted by like reference numerals.

[0033] Referring now to FIGS. 1 and 2 a shoe last 1 is a solid cast made to resemble the human foot. A last 1 can be made of different materials but its construction is based on the same principles. In correspondence with a foot, a last 1 may be divided into toes, a fore portion, a waist, a heel area, an upper portion and a base. The front point of the base of the last is typically at an angle from the horizontal to define a space between the toe portion and the horizontal plane; this distance is known as the toe spring 3. Similarly, the height of the last corresponding to the height of the hallux tip point is called toe depth 5.

[0034] The front portion of the last is defined by a first point representing the first metatarsophalangeal joint A of a foot and a second point representing the fifth metatarsophalangeal joint B of a foot. An imaginary line on the base of the last between the first and second points is known as the bottom support surface or tread point 2 and corresponds to the ball of a foot. The circumference of the last between these joint points defines the ball girth 8. This anterior portion of the last defines the toe box, that is, the portion arranged to cover and protect the toes in a shoe. If a last 1 is for manufacturing high heels, the base of the heel is on a horizontal plane higher than that of the tread point 2. The vertical distance between the base of the heel portion and the tread point 2 is known as heel elevation 6 while the curve defined by the outline of the contoured base of the last is called heel gradient or pitch. According to an embodiment of the present invention, a last is graded across European shoe sizes 36 to 42 and is shaped to accommodate a foot with a bunion and/or bunionette. When designing a last in accordance with European tradition, it is generally accepted that three traditional reference points will be used as a marker on the last instead of the ball girth 8. These reference points are selected for ease of visibility on the last and allow for accurate measurements when the lasts are graded across different sizes. These reference points are located on either side of the last 1 and the top of the last and are placed a little closer to the heel relative to points A and B and the ball girth. The sizing measurements consist of measuring the circumference 9 around these reference points, this dimension will be referred to as reference point circumference 9 and is typically located between the standard ball girth 8 and instep girth (not shown). Thus, the reference point circumference 9 is located around 0.5 to 20 mm higher relative to the ball girth 8. A last in accordance with an embodiment of the present invention comprises a reference point circumference 9, a ball girth 8 and a bottom support surface 2 width greater than those used in standard lasts. Specifically, for a European size 37, the ball girth is between 227 mm and 229 mm while the tread point or bottom support surface 2 measures between 79 mm and 82.5 mm. The bottom support surface 2 provides an increase between 1 and 4 mm in relation to a standard tread point for an equivalent standard last, which is typically around 76-78 mm. Further, the reference point circumference 9 for a European size 37 is between 223 mm and 234 mm, and increases or decreases by 2 to 2.5 mm per half size. This represents an increase in reference point circumference, usually in a range of 215 to 220 mm and generally about 218 mm, of between 9 and 16 mm over a standard last. Accordingly, the reference point circumference 9 of the last of the present invention is increased by the equivalent of two to three European shoe sizes relative to the traditional reference point circumference of a standard last of the same type. However, the overall appearance of a shoe produced using the last of the present invention is not significantly altered. Finally, toe depth 5 is also increased for the purposes of this invention, from a standard toe depth of 14 mm to a depth of 20-21 mm.

[0035] The length 11 of a last for a heeled European size 37 shoe is approximately between 253 and 263 mm increasing or decreasing by 3.3 mm per half a size assuming the heel elevation 6 is approximately between 4 and 9 cm. The last 1 usually has a toe spring 3 in a range of 9 to 12 mm. Development of the last 1 of the present invention was carried out by hand-carving traditional wooden lasts and then using said wooden lasts to mould a final last in polyethylene resin. Intermediate adjustments were carried out by shaving the traditional wooden lasts with a rasp and or adding small amounts of putty to the lasts. After each adjustment, a revised version of the wooden last was made. Subsequently, a corresponding polyethylene version was also made. To manufacture a shoe in accordance with a preferred embodiment of the present invention described below in relation to FIGS. 2 to 9, the wooden last, corresponding lasting socks (defined below), heels, uppers, insoles and outsoles were manufactured and samples produced. At each sampling stage, a revised shoe was tested.

[0036] As mentioned above in relation to FIGS. 1 and 2, the last used to produce a shoe in accordance with the invention has a reference point circumference 9 which is between 9 and 20 mm, preferably between 9 and 15 mm, greater than that of a standard shoe. As a result, the reference point circumference is equivalent to the reference point circumference of a shoe approximately two to three numerical sizes larger while the remainder of the shoe (i.e. overall length, heel width, etc.) is equivalent to its numerical size. This allows a hallux valgus sufferer to wear the correct size shoe with reduced or without pain caused by an ill-fitting toe box.

[0037] The following table shows four examples of a size 37 last according to the present invention:

TABLE-US-00001 Example 1 Example 2 Example 3 Example 4 Reference point 218 mm 220 mm 215.5 mm 213.5 mm circumference of a standard last Reference point 232.8 mm 234 mm 224.5 mm 223.5 mm circumference of a last according to the invention Difference 14.5 mm 14 mm 9 mm 10 mm

[0038] Examples 1, 2 and 3 relate to lasts having a heel elevation of between 40 and 80 mm. Example 4 relates to a last arranged to be used in the manufacture of flat footwear (i.e. footwear having a heel elevation of no more than 25 mm).

[0039] Referring now to FIG. 3 there is shown an article of footwear according to an embodiment of the present invention. The article is a shoe 20 comprising a vamp or shoe upper 22 to secure the shoe 20 onto the foot, a vamp lining 23 to insulate a wearer's foot, an insole 27, 29 arranged to receive a foot and insulate its sole, a midsole to provide shock absorption, support and cushioning, an outsole 40 arranged to contact the ground and a heel 42. The shoe upper 22 comprises an outer layer 21 and an inner layer formed by a vamp lining 23 and an elastic panel 25 arranged to fit over the first metatarsophangeal joint of a foot, roughly covering the area from the base of a hallux to the area surrounding a first metatarsal. The outer layer 21 is made of a first material such as leather, suede or fabric and has a first elastic modulus while the elastic panel 25 is made from a second material described in detail with reference to FIGS. 4a and 4b below, which material has a second elastic modulus. The second elastic modulus is lower than the first elastic modulus; thus, the elastic panel 25 is much more flexible than the outer layer 21. The insole comprises a sock lining 29 arranged to cover the foot bed of the shoe and to come into contact with a wearer's foot and an arch portion 27 attached to the sock lining 29 and arranged to receive a wearer's medial longitudinal arch. The midsole is formed by three distinct layers 32, 34, 36. A cushioning top layer 32 is provided under the sock lining 29. The cushioning layer generally has the same outline as the sock lining 29 but with a slimmer contour, a truncated anterior portion and a cut-out portion arranged to receive an anti-pronation element 33, which anti-pronation element 33 is provided on the arch portion of the foot bed under the arch portion 27 of the insole, adjacent to and on the side of the cushioning layer 32. The midsole further comprises a middle layer 34 located on the base of the foot bed and arranged to provide additional cushioning and support for the ball of the wearer's foot. Finally, the midsole comprises a base layer 36 provided between the middle layer 34 and a lasting sock 39. The base layer 36 provides shock absorption and resilience. The lasting sock 39 which comprises a shank, a sock layer and a further half-length layer is formed of any suitable material such as cellulose fibre, leather board, or non-woven materials, in use, is secured to the outsole and the heel 42. Upon assembly, the elastic panel 25 is secured to the lining 23 and the resulting inner layer is secured to the vamp outer layer 21 to form the shoe upper 22. Further, the base and middle layers of the midsole are secured to the lasting sock 39 to form a lasting assembly. The cushioning layer 32 and anti-pronation element 33 are secured to the underside of the lining sock 29 and the arch portion lining 27 respectively. Subsequently, the shoe upper 22 and the lasting assembly are secured to each other over the last described in relation to FIGS. 1 and 2 above. Then, the outsole 40 and heel 42 are secured to the underside of the lasting sock 39 while a heel-piece 43 is secured to the free end of the heel 42. Finally, the assembly formed by the cushioning layer 32, anti-pronation element 33, lining sock 29 and the arch portion lining 27 are secured to the footbed to create an assembled shoe 20.

[0040] In use, the elastic panel 25 is arranged to provide cushioning and protection over the first metatarsophangeal joint while remaining invisible from the outside of the assembled shoe 20. When the shoe 20 is not in use, the elastic panel 25 returns to its original shape. Referring now to FIGS. 4a and 4b, the elastic panel 25 is preferably made from sheet polychloroprene, also known as NEOPRENE, which can be produced as a fine layer, has a 100% memory, is highly elastic and is also highly resistant. Said sheet material is cut into a contoured elastic panel using the patterns 250 shown in FIG. 4a or 4b. The patterns 250 have channels 260 arranged to allow the polychloroprene to be marked. The markings indicate the section of the panel 25 which will be secured to the lasting assembly when the shoe is constructed. Upon assembly, the elastic panel 25 is sewn to the lining 23 at 1 cm from the top line of the shoe 20 to allow for stitching of the elastic panel 25 to the lining and for stitching of the inner layer to the shoe upper 22. In a preferred embodiment of the invention, the elastic panel 25 has a thickness of 1 mm to provide a lighter support, protection, and compression, thereby allowing a greater degree of motion and functional use. In this embodiment, the polychloroprene sheet is foamed thereby allowing minimal air and water exchange and providing excellent insulation. Further, the elastic modulus of the polychloroprene used is between two and three orders of magnitude lower than the elastic modulus of leather. Generally, the elastic modulus of polychloroprene is between 0.7 and 2 MPa (0.0007 0.002 GPa), although any suitable material with an elastic modulus lower than 50 MPa (0.05 GPa), preferably lower than 5 MPa (0.005 GPa) would be suitable. The elastic modulus at 200% of the polychloroprene used in this embodiment is 1-3 kg/cm.sup.2 or 0.098-0.29 MPa while tensile strength is higher than 6 kg/cm.sup.2 (0.59 MPa) and tear strength/resistance is higher than 2 kg/cm. Use of polychloroprene is advantageous because it is known to decrease shear stress to tissue and bony prominences such as bunions. Typically, the raw polychloroprene pattern is provided with a one-sided or double-sided protective covering. In a preferred embodiment, the polychloroprene elastic panel is provided with a nylon covering. Nylon has been used because it allows the material to stretch and marginally increases thickness of the panel. Advantageously, a one-sided covering reduces the amount of skiving , that is paring of the edge of the material to reduce its thickness, required on the reverse side of the elastic panel thereby ensuring that said panel is not visible from the outside of the shoe when said shoe is worn. The height of the elastic panel is calculated so that it adequately fits over the first metatarsophangeal joint and its vertical edge is positioned within the lining where the base of the hallux is received by the shoe. The maximum height of the elastic panel is also determined by the last used and by the specific pattern of the shoe. The elastic panel pattern of FIG. 4b is made in accordance with a pattern cut to three distinct alternatives designed to accommodate different shoe sizes, a first alternative to accommodate a European shoe size 36-37.5, a second alternative to accommodate a European shoe size 38-39.5 and a third alternative to accommodate a European shoe size 40-41.5. In the elastic panel pattern shown in FIG. 4a, the alternatives accommodate European shoe sizes 37-38.5, 39-40 and 40.5-41.5.

[0041] Referring now to FIG. 5, the shoe of the present invention has a wider tread point that a standard shoe. Accordingly, the lining sock 29 the anterior portion of the lining sock 29 is wider than a standard lining sock. In this particular embodiment, the lining sock 29 and arch portion 27 are made of leather. The cushioning layer 32 provides additional cushioning from the heel to the ball of a foot, as described in detail in relation to FIG. 6. Further, the anti-pronation element 33 abuts the cut-out portion of the cushioning layer 32 to provide additional support and ensure correct alignment of a wearer's medial longitudinal arch without causing discomfort. The anti-pronation element 33 is made from a cushioning and stabilising material such as polyurethane memory foam, preferably anti-bacterial and air-permeable polyurethane memory foam. On assembly, the lining sock 29 and the arch portion 27 attached thereto are secured to the cushioning layer 32 and anti-pronation element 33 respectively with adhesive. The edges of the lining sock 29, shown as a hatched section, are skived to ensure a comfortable fit of the shoe. Further, the contour of the cushioning layer is also skived. Once the insole 27,29 is secured to the cushioning layer 32 and anti-pronation element 33, the cushioning layer and anti-pronation element are secured to the middle layer and lasting sock 39.

[0042] Referring now to FIG. 6, the cushioning 32, middle 34 and base 36 layers of the midsole 30 are made of a shock absorbent and resilient material which is preferably also anti-bacterial and air-permeable. A suitable material is, for example, urethane memory foam, preferably anti-bacterial and air-permeable. In this embodiment, said layers are made of PORON Urethanes from Rogers Corporation, Inc. The materials used allow the midsole 30 to adapt to the individual foot shape and return to the original shape when the shoe 20 is not in use. The portion arranged to receive the ball of a foot is the thickest part of the forefoot portion of the midsole 30 and has a thickness of 7 mm. Further, it combines the properties of the three different layers 32, 34, 36 to ensure maximum shock absorption and cushioning under the ball of a foot. As mentioned above, the anterior front portions of the base and middle layers 34, 36 are skived and therefore have a truncated shape to increase comfort under the toes by maximising space in the anterior portion of the toe box. The hind foot and midfoot portion of the midsole, which is formed solely by the cushioning layer 32, has a thickness of 3 mm and provides cushioning as described in more detail below. The midsole 30 does not significantly alter the appearance of the shoe 20.

[0043] The cushioning layer 32 is provided under the lining 29. In this embodiment the cushioning layer 32 is made of PORON Plus Cushioning memory foam having a thickness of 3 mm. This cushioning layer 32 is lightweight and flexible and combines a cushioning effect with energy return to protect joints and soft tissue. The cushioning layer 32 is adhered to the length of the leather lining 29 and its outline is contoured to provide a cut-out portion arranged to receive the anti-pronation element 33. Further, the contoured shape of the cushioning layer 32 provides clearance over the front and back sections of the lasting sock 39a and 39b. The edge of the anterior portion of the cushioning layer is skived to maximise space for the wearer's toes in the toe box. The contoured edges of the cushioning layer 32 are also skived. In this example the shoe 20 comprises a heel 42 and therefore the base of the foot bed corresponds to the ball of a wearer's foot. The middle layer 34 is contoured to provide additional cushioning for the ball of a foot. The memory foam used in this instance is PORON Slow Rebound Soft. This memory foam has lower compression force deflection and resilience properties than those of the memory foam used for the cushioning layer 32. As a result, the middle layer 34 provides additional stability and improves balance of a wearer. The middle layer 34 has a thickness of 2 mm and, in use, is adhered to the base layer 36 as described below. The anterior edge of the toe portion of the middle layer 34, defined by the broken line shown in FIG. 6, has a truncated shape and is skived to ensure a comfortable fitting. The cushioning layer 32 is secured to the middle layer 34 with adhesive. The base layer 36 is contoured to the shape of the middle layer 34 and is sandwiched between the middle layer 34 and the lasting sock 39. In this embodiment, said base layer 36 is made of PORON Performance material. This particular type of memory foam is highly shock absorbent and resilient thereby providing protection from walking impact to a wearer. Further, it also provides energy return. The base layer 36 used in this example has a thickness of 2 mm. The anterior portion of the base layer 36 is longer than the anterior portion of the middle layer 34 and also has a truncated shape. The anterior edge of the base layer 36 is additionally skived to provide a comfortable fitting. When assembled, the base layer 36 is adhered to the front portion of the lasting sock 39a.

[0044] By combining a base 36 and a middle layer 34 on the front portion of the lasting sock 39a, the shoe 20 of the present invention allows the properties of both layers 34, 36 to merge thus providing excellent shock absorption, stability and comfort for joints and soft tissue. The combined layers 34, 36 distribute pressure evenly thereby improving support and stability. Further, each material of the midsole 30 returns to its original shape after use and moulds to a foot when worn; therefore the shoe 20 provides a customised fit every wear. It should be noted that although the middle 34 and base layers 36 of the midsole 30 in this embodiment are provided as a double layer, either layer could be absent or both layers could be integral.

[0045] As mentioned above, hallux valgus is typically worsened by over-pronation, whether to account for the deviated bones, due to pes planus (flat feet) or both. In a preferred embodiment, the present invention comprises an element 33 arranged to prevent over-pronation. As shown in FIG. 7, the anti-pronation element 33 is formed by a pad made from polyurethane memory foam. Preferably, the polyurethane memory foam has low-density and is therefore breathable and resistant to bacterial and fungal growth. In use, the anti-pronation element 33 is arranged to provide additional support, keep a wearer's foot in the correct alignment and prevent the foot from rolling inwards when walking, i.e. over-pronating. In this particular embodiment the anti-pronation element 33 measures 6.2 cm in length (I), 3.3 cm in width (w) and 0.5 cm at the highest point (h). The edges and surfaces of the element are contoured to abut the cut-out portion of the cushioning layer 32 and adapt to a foot when the shoe 20 is worn. Thus, the anti-pronation element 33 is large enough to improve the position of a foot but not large enough to increase pressure on the medial longitudinal arch of a wearer's foot. As a result, the anti-pronation element 33 provides support to over-pronators and is comfortable for shoe wearers who do not suffer from over-pronation.

[0046] Although the article of footwear described above comprises an elastic panel arranged to cover the first metatarsophalangeal joint of a user, it should be obvious to the skilled person that a second panel could be arranged to cover the fifth metatarsophalangeal joint of a user. Further, it should also be apparent that an article of footwear may comprise a single elastic panel arranged to cover the fifth metatarsophalangeal joint. Moreover, it should also be clear that an article of footwear may include a lining made from polychloroprene or a toe box lining made from polychloroprene, in this case, the lining would be the elastic panel.

[0047] It should be apparent to the skilled person that materials other than polychloroprene or the specific polychloroprene described above could be used to manufacture the elastic panel. For example, NEOGREEN, Guayule, THERMOCLINE material from Fourth Element Limited or ARIAPRENE synthetic rubber material.

[0048] Additionally, it should also be apparent that the elastic modulus of the material used could be different to that described above and that an elastic modulus lower than 50 MPa (0.05 GPa) could be suitable.

[0049] Moreover, it should be clear that the pattern for the elastic panel could have a universal size or could be sized in accordance with numerical sizes and/or half sizes.

[0050] In addition, it should be obvious that the midsole described above could have one integral layer comprising two layers of memory foam or two instead layers of the three layer construction described above.

[0051] It should also be apparent that any suitable alternative to the urethane memory foams described above could be used.

[0052] Although specific dimensions for an anti-pronation element have been defined, it should be clear to a skilled person that an anti-pronation element could be manufactured in a range of different sizes comprising a length of 5 to 7.5 cm, a width of 3 to 4 cm and a height of 2 to 8 mm.

[0053] Further, the last and article of footwear described above have a specific heel elevation and a heel gradient; however, it should be obvious that both heel elevation and gradient can be varied to produce, for example, a flat shoe having no heel elevation or gradient or a minimal heel elevation and gradient. It should also be apparent to a skilled person that the last length mentioned above is an example and is variable depending on heel elevation and heel gradient. In addition, the lasting sock construction described could be replaced with any other suitable lasting sock construction.

[0054] Although the shoe described in relation to the above figures has a pointed toe, it should be clear to a skilled person that this is not necessary and that the toe box may have any shape, for example almond toe, round toe or peep toe. Further, it should also be clear that the invention could be applied to any other type of footwear such as boots, slingbacks, mules, sandals, flat shoes, etc. It should also be obvious that types of shoes that do not have a closed heel construction, such as slingbacks or mules may not include an anti-pronation element, depending on the shoe design. Further, the elastic panel may be cut or split in sandals and other types of shoe.
