Proper posture high-heeled shoes

Abstract

A high-heeled shoe for a human foot which enables a person wearing it to stand and walk in an anatomically correct (suitable) position, i.e. to walk just like when she walks with heelless flat shoes; enables the body to stand in balance and the foot to rest on all points. The high-heeled shoe is formed with a curving inclined supporting sole which extends into the heel with the curve being adjusted with arctangent values and a correction factor and toe and heel angles appropriate for a human foot to provide perfect conformity with the human foot for straight body posture suitable to anatomy.

DETAILED DESCRIPTION

(10) The components shown in the figures are each given the common component reference numbers as follows: 1. High heeled shoe 2. Insole board as measured from the point at which the insole board in contact with the foot rises and extending to the back or rear of the shoe. 3. Heel as part of the insole board and supporting the rear or heel of the wearer 4. Front platform extending forward from the rising point of the insole board 5. Toe as the front of the shoe

(11) Table 1 provides the sole alignments where the proper curvature is realized and is computed by using the equation:
K=4/i(Equation 4)

(12) whereby i is K, given in Equation 2, divided by 4.

(13) Table 1 shows the sole alignments (x values) where the greatest curvature takes place by using equation 4 is as follows:

(14) TABLE-US-00001 TABLE 1 i 1 2 3 4 5 6 7 8 9 10 x 0.88 1.22 1.47 1.68 1.86 2.02 2.18 2.32 2.46 2.59 i 11 12 13 14 15 16 17 18 19 20 x 2.73 2.86 3.00 3.13 3.27 3.41 3.55 3.68 3.82 3.97

(15) In the light of these data, it is appears that in order to reach the alignment where the greatest bending takes place when k is decreasing, k should be minimized. When the obtained figure is examined, it is observed that the insole (2) angle and the heel (3) angle increase more than expected as k value decreases. A factor function is required in order to shift the bending alignment backwards without increasing the heel (3) angle very much.

EXAMPLES

(16) Ten different sole trials are made by calculation, with heels of varying heights ranging from 2 to 4 (5.08 to 10.16 cm) to obtain sole or insole board curvatures complying with equation 1 and the correction coefficient, with the ideal forms of the A.sub.1, A.sub.2, A.sub.3, A.sub.4, A.sub.5, A.sub.6 insole boards for use with heels of 2, 2, 3, 3 and 4, 4.5 being obtained (or derived). The suitable correction factor used with equation 1 is the below given equation 5 as calculated using parameters of the MatLab software program.
1/(1+(xx.sub.j)2/k.sub.2),x[0,100](Equation 5)
wherein the variable x, for the heel sizes of A.sub.1, A.sub.2, A.sub.3, A.sub.4, A.sub.5, A.sub.6 are given in Table 4 below, with:

(17) x.sub.j being the variable used for changing the effect of the factor function in the formula so that the insole board is more suitable to the human foot anatomy. And variable k.sub.2 is the variable used for changing the effect of the factor function in the formula so that the insole board is more suitable to the human foot anatomy and which has been determined to be 300.

(18) With the corrected formula that is obtained, the A.sub.2, A.sub.3, A.sub.4, A.sub.5, and A.sub.6 insole boards, are formed and these models are observed experimentally (as direct foot supports) and are seen to be successful in providing both anatomically correct support and increased comfort for the wearers.

(19) Table 2 shows that A.sub.1, A.sub.2, A.sub.3, A.sub.4, A.sub.5, and A.sub.6 inboard soles can be produced in high heeled shoes without front platforms, with a height ranging from about 2 to 4.5 and as high heeled shoes, with appropriately sized front platforms with a height ranging from about 0 to 3.5 provided that the elevation distance between the front of the foot wearing the shoe to the heel is no more than about 4.5, i.e. with appropriate platforms ranging from 0 to 3.5 for the aforementioned heels.

(20) The high heeled shoe's (1) toe angles () and heel angles () shown in the Figures vary relative to the insole board (2) so as to ensure a straight body posture. The heel angle () corresponding to the toe angle () of each high-heeled shoe (1) is given in Table 2. As seen in Table 2, shoe heels that range from 2 inches to about 8 inches preferably have () heel angle values in the range of about 5 to 26 (with a 10% possible deviation) as shown in FIG. 7. The variation of heel angles is a function of one or two factors. The first one being the difference of the varying heel heights (cm/inch), and the second being the differences exhibited by the materials used in manufacturing the high heeled shoe such as the lasting process. The best results (posture and comfort) are obtained when the toe angle () of the high-heeled shoe (1) is at angles varying between 7 and 26. The heel angle () is a function of insole board curvature calculation with the heel being the rear terminus thereof but with variations thereof, in the given range, being functionally determined by the manufacturing process.

(21) Generally, a typical heel section distance ranges between 35 to 50 mm from the rear of the shoe with a heel angle being measured therefrom such as with wedge shoes and may be smaller with respect to very narrow stilletto heels. Calculations of heel angles and ranges thereof as made herein are generally determined with a length of between 35 to 50 mm from the rear of the shoe along the foot support.

(22) The distances provided for the following Table 2 for the insole boards with heel heights, as indicated for A.sub.1-A.sub.6, begin at the rear of the shoe and end of the insole board and extend along the length of the insole board.

(23) TABLE-US-00002 TABLE 2 Distance Along the Insole Board from Rear of Shoe Heel 90-100 80-90 70-80 60-70 50-60 40-50 30-40 20-30 10-20 0-10 Heel Toe Height mm mm mm mm mm mm mm mm mm mm Angle () Angle () A.sub.1 (2) 42.96 41.97 38.66 33.89 28.43 22.83 17.41 12.36 7.78 3.75 5-9 7-26 A.sub.2 (2) 45.63 44.02 39.84 34.11 27.75 21.42 15.49 10.17 5.53 1.59 12-16 7-26 A.sub.3 (3) 49.61 46.92 41.20 33.86 26.16 18.93 12.54 7.10 2.60 0.27 14-18 7-26 A.sub.4 (3) 51.72 48.40 41.77 33.51 25.11 17.46 10.91 5.50 1.14 0.00 16-20 7-26 A.sub.5 (4) 56.13 51.32 42.52 32.18 22.35 14.03 7.38 2.20 0.00 0.00 18-22 7-26 A.sub.6 (4) 58.43 52.74 42.63 31.10 20.60 12.07 5.48 0.51 0.00 0.00 22-26 7-26

(24) It is understood that insole board models obtained by the aforementioned formula 1 with correction factor, as described are suitable for proper posture and comfort though there may be deviation of a few degrees for either the toe angles () and heel angles () within the aforementioned range parameters. Ranges of deviation with deviations in comfort levels, at their outer limits, are defined by the values for adjacent heel heights in the table. Thus, for example, at the 90-100 mm distance point the degree curve value for A.sub.1 can range from 42.96 to the 45.63 of A.sub.2. For A.sub.2 the value ranges from 42.96 of A.sub.1 to the 49.61 of A.sub.3 from the values of A.sub.1 to A.sub.3. Similarly for A.sub.3 the value ranges from the 45.63 of A.sub.2 to the 51.72 of A.sub.4 and for A.sub.4 the value ranges from the 49.61 of A.sub.3 to the 56.13 of A.sub.5. The range for A.sub.5 is from the 51.72 of A.sub.4 to the 58.43 of A.sub.6. The value for A.sub.6 is from the 56.13 of A.sub.5 to the 58.43 of A.sub.6. The values for A.sub.1 and A.sub.6 are respective minimums and maximums with possible deviation. The range is extended similarly over the various distance points.

(25) In an analogous manner the heel angles may vary in the ranges between adjacent heel heights A.sub.1 to A.sub.6 as given in the table for the specific heel heights with heels angles for A.sub.1 being between 5-16, for A.sub.2 being between 5-18, for A.sub.3 being between 12-20, for A.sub.4 being between 14-22, for A.sub.5 being between 16-26, and for A.sub.6 being between 18-26 with the values for A.sub.1 and A.sub.6 being respective minimums and maximums (with possible deviations of up to 10%).

(26) Determination of curve angles at specific positions and curve values for operable ranges for heel heights which fall within to 2-4.5 range and different from the specific A.sub.1 to A.sub.6 heights, the x.sub.j and k values of Table 4 are used to provide the extrapolation of range values between the adjacent A.sub.1 to A.sub.6 values.

(27) Accordingly, modeling can be effectively applied to many different insole boards by using the formula for intermediate heel height values, by interpolating with use of the values of the A.sub.1-A.sub.6 model insole boards in the Tables 2 and 3. Insole boards made with the intermediate heel heights are acceptable from a proper posture comfort consideration. Insole boards made with the intermediate values can be used in the production of successful shoes similarly without being affected by deviations of few degrees. The intermediate values of the A values are provided in the below given Table 3.

(29) When the A.sub.1, A.sub.2, A.sub.3, A.sub.4, A.sub.5, A.sub.6 insole boards are being formed, the variables x.sub.j, k and k.sub.2 given in Table 4, are used as described above, with k being a variable function of the MatLab algorithm. k.sub.2 given in this table is the variable used for changing the effect of the factor function in the formula so that the insole board is more suitable to foot anatomy and which has been empirically determined to be 300.

(31) With reference to the drawings, as shown in FIGS. 1 and 3, typical high-heeled shoes 1 comprise a toe section 5, a sole or platform section 4 which can provide an elevated rest for the front of the foot, as shown in FIG. 1, or may be of minimal thickness as shown in FIG. 3. The insole board or direct foot support section 2 extends from and is usually integrated with sole or platform section 2 and begins at the elevation point shown, for insole board 2 in FIG. 2. The insole board 2 rises, usually as a curved section toward the rear or heel of the shoe where a portion thereof is supported by heel 3, shown in different configurations in FIGS. 1 and 3. The heel of a wearer of the shoe 1, shown in FIGS. 8A and 8B rests on and is supported by heel 3 in both the prior art shoe of FIG. 8A and that of the present invention of FIG. 8B. The heel angle () of the shoes of the present invention, shown in FIG. 2 and FIG. 7, are at relatively low levels of 5-26, generally considerably below those of heel angles in high-heeled shoe of the prior art. Though toe angles can be flush with the ground, such as with the shoe of FIG. 1, for better posture and increased comfort, the front toe angle () should be slightly elevated with an angle ranging from 7 to 26 with little or no variation from this range.

(32) The curve of the insole board 2 of both prior art shoes and that of the present invention is defined by an x, y axis coordinate system superimposed on the insole board with a point of origin at the point of the insole board 2 where the insole board begins to rise as shown in FIG. 2. Each point on the insole board is defined by the interrelated x and y parameter values. The curvature of the insole board is determined by a function k, as shown in FIG. 4 which can range from limited curvature with low k values to highly curved shapes with the various curvatures providing different degrees of support and or comfort/discomfort and proper foot and positioning and posture.

(33) As shown in the x-y graph of FIG. 5, five insole boards, A.sub.1-A.sub.5 are made in accordance with the present invention with utilization of equation 1, as corrected with the correction factor of equation 5, for every x, y value of the curve and with a k.sub.2 constant value being 300 and as represented by different curves. The A.sub.1-A.sub.6 insole boards were made for heel heights of 2, 2, 3, 3, 4 and 4.5 respectively. FIG. 6 depicts in detail the curve for the A.sub.5 insole board with a 4 heel.

(34) FIGS. 8A and 8B show the position and posture bearing of a wearer of a prior art shoe 1 (FIG. 8A) and a shoe of the present invention 1 (FIG. 8B) wherein the proper upright axis A for the prior art shoe wearer shows a front leaning deviation from a proper posture, a lack of full support and a resultant forward toe pressure engendering typical high heel shoe pain. There is also a lack of support in the arch area 9. In contrast the shoe 1 in FIG. 8B provides full support throughout the arch and with the heel being fully support such that the wearer is erect along axis A with a more aesthetic and statuesque appearance, with the shows of FIGS. 8A and 8B showing very little discernible difference in stylish appearance.

(35) FIG. 9 shows a high-heeled shoe embodiment known as a wedge shoe wherein a fully supported sole is used in place of a steel insole board as used in the other embodiments. The curvature of sole 2 is substantially identical to that of the embodiments with the insole board.

(36) It is understood that the above disclosure and examples are merely exemplary of the present invention and that changes in materials, structures, configurations and the like such as additional cushioning at pressure or normal pain sites on the shoe insole especially at or near the heel are possible without departing from the scope of the present invention as defined by the following claims.
