Definitions

  • the present invention relates to high-heeled shoes and particularly to those which enable wearers to assume and maintain anatomically suitable postures while standing and walking.
  • a foot structure may be divided into three recognizable parts. Starting from the rear, a first part, i.e. the heel, is comprised of talus and calcaneus. The second or middle part is comprised of the navicular bone, metatarsal bones and other bones
  • the foot There are two arch systems in the foot; one is the transverse arch at the front part of the foot.
  • the second or other longitudinal arch starts from the calcaneus and follows the inner part of the foot until the base joint of the big toe.
  • the arch at the front part is shaped by the ligaments, which maintain the form of the arch when no load acts on the foot and the stretches as it is pressed to the ground when a load is exerted on the foot.
  • the plantar aponeurosis (arch ligament) that extends from the calcaneus to the toes also stretches. The more the load is exerted on the arch, the more the ligaments stretch. Many movements of the foot and the toes are controlled by the muscles which start from the lower part of the leg and whose tendons adhere to the foot.
  • Muscles control finer movements of the foot, which muscles begin and are adhered on the foot itself. Many movements of the foot are provided by the muscles at the bottom part of the leg, via ligaments. Standing, walking and running functions of the foot are made possible by contraction of these muscles. Many small muscles, apart from the above, produce a base at the sole of the foot with their positions between the bones.
  • Another objective of the present invention is to provide a high-heeled shoe, which enables the body of the wearer to stand in correct balance and the foot to rest on all points.
  • a further objective of the present invention is to provide a high-heeled shoe, which enables the wearer to assume and maintain anatomically suitable straight body posture with a high degree of comfort not normally obtainable with high- heeled shoe configurations particularly of the stylish type.
  • the present invention comprises high- heeled shoes of heel heights in excess of two inches (5.08 cm) configured with component elements in an inter- relational angular and length of proper configuration structure, wherein foot stress and discomfort is minimized while retaining aesthetic appearance thereof.
  • anatomically suitable straight body posture and concomitant comfort can be achieved in high heeled shoes by adjusting the arctangent values, as described hereinafter, with substantially exact conformity. This can be made possible only by adjusting the center of gravity such that it will be on the rear or middle part of the foot.
  • straight body posture can be achieved by bringing the body to a position suitable to a healthy anatomy.
  • Foot support in high-heel shoe construction and components involved therewith entails understanding and definition of the parts thereof.
  • a first part, which is normally in contact with the bottom of the foot is the "Insole Board". This is a firm part of the shoe that is directly under the entire back part of the foot in most footwear. It usually starts from the back portion of the shoe (heel section) and often extends until either the toe section or until the end of the curvature of the bottom of the foot.
  • the insole board usually has another layer of cushion and/or a layer of insole lining on top of it. This thickness of the lining may and often does vary.
  • the "Shank” is a support (often metal such as steel, or it can be made of fiberglass or other strong materials) that is placed at some point under the insole board to support the shape of the insole board and the weight that is placed on the insole by the wearer. It has no fixed placement position; but its curve needs to match the curve of the insole board at the position that it is placed under (or sometimes over) the insole board.
  • the "curvature” is normally that of the "insole board", or anything else in the shoe that is directly under the wearer's foot and which starts from the back of the foot and extends forward till it reaches the point of no further descent (i.e., essentially plateaus).
  • the insole board usually has another layer of cushion and/or a layer of insole lining on top of that.
  • the thickness of the lining may vary and thus affect parameters of curvature.
  • the curvature as specified herein is one that is attained when the wearer places her/his weight on the shoe and the shape that remains directly under his foot after repeated wearings of the shoe ( after the cushioning has settled after some initial use, or in case of strong cushioning that retains its shape- at the first wearing) is the "curvature" as used herein.
  • the value of k is empirically determined and as determined, varies in accordance with heel height with various values being set forth in Table 4 below (with extrapolation and variations thereof being determined for other heel heights and operable ranges for the specific heel heights).
  • the k 2 factor (as used in a correction factor set forth below) denotes, for a curvature factor, a constant value of 300, obtained as a result of experimental studies in determining anatomically correct position and maximum comfort in accordance with the present invention.
  • the y coordinate value denotes the length, which extends from the horizontal part of the coordinate plane to the point where the insole board is positioned.
  • the x and y values given in the equations are each a value of length, with the y value varying in accordance with the change of x distance along the insole board position.
  • K y / (l + (yT) (Equation 2) wherein K denotes a value that changes with respect to the first derivative of y (y') and the second derivative of y (y") given in equation 2.
  • the high- heeled shoe configuration relative to heel and platform height of a particular high-heeled shoe which enables anatomically suitable body posture and walking, and has orthopedic inclination and high heels in accordance with the present invention, comprises the elements and parameters of:
  • At least one front platform which is formed to raise the foot above the ground by a selected height, and at least one toe which is located at the place where the tip of the foot is placed and whose angle can be changed by a desired amount between about 7° to 26° (with a possible 10% deviation).
  • Figure 2 is a side view of the insole board of the high- heeled shoe of Figure 1 indicating angles of modification and x-y components of angular gradients of the insole board elevation;
  • Figure 3 is the side view of another embodiment of the high-heeled shoe of Figure 1, with a reduced width heel;
  • Figures 5 is a graphical representation of the curvature change of the A l , A 2 ,
  • heel heights of 2", 21 ⁇ 2", 3", 31 ⁇ 2", 4" and 4.5 respectively, which can be produced with different curvatures with respect to x and y axes at different points of the insole board curve;
  • Figure 6 is an insole board and a graphical representation of the insole board, which provides the x-y inclination parameter in accordance with the present invention for a 4 inch heel
  • Figure 7 is a left side view of a high-heeled shoe of the invention showing heel angles (a) and heel support configurations, as shown in Figure 2, for a shoe with a heel ranging from about 2-4.5 inches;
  • Figures 8A and 8B depict the differences in position of a human leg while wearing a high heeled shoe of the prior art (8 A) and the present invention (8B); and:
  • Figure 9 shows a wedge type embodiment of a high-heeled shoe in which the parameters of the present invention of appropriate sole curvature have been embodied.
  • 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.
  • Table 1 provides the sole alignments where the proper "curvature” is realized and is computed by using the “equation”:
  • Table 1 shows the sole alignments (x values) where the greatest "curvature” takes place by using equation 4 is as follows: i 1 2 3 4 5 6 7 8 9 10
  • variable Xj for the heel sizes of A l , A 2 , A 3 , A 4 , A 5 , A 6 are given in Table 4 below, with: Xj 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 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.
  • Table 2 shows that Ai, A 2 , A 3, At , A 5> and A 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.
  • the best results are obtained when the toe angle ( ⁇ ) of the high-heeled shoe (1) is at angles varying between 7° and 26°.
  • the heel angle (a) 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.
  • 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 50mm from the rear of the shoe along the foot support.
  • a 3 the value ranges from the 45.63° of A 2 to the 51.72° of A4 and for A4 the value ranges from the 49.61° of A 3 to the 56.13° of A 5 .
  • the range for A 5 is from the 51.72° of A 4 to the 58.43° of A 6 .
  • the value for A 6 is from the 56.13° of A 5 to the 58.43° of A 6.
  • the values for Ai and A 6 are respective minimums and maximums with possible deviation. The range is extended similarly over the various distance points.
  • heel angles a may vary in the ranges between adjacent heel heights Ai to A 6 as given in the table for the specific heel heights with heels angles for Ai being between 5°- 16°, for A 2 being between 5°- 18°, for A 3 being between 12°-20°, for A 4 being between 14°-22°, for A 5 being between 16°-26°, and for A 6 being between 18°-26° with the values for Ai and A 6 being respective minimums and maximums (with possible deviations of up to 10%).
  • the Xj and k values of Table 4 are used to provide the extrapolation of range values between the adjacent Ai to A 6 values.
  • 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 Ai - A 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.
  • 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 Figure 1, or may be of minimal thickness as shown in Figure 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 Figure 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 Figures 1 and 3.
  • the heel of a wearer of the shoe 1, shown in Figures 8 A and 8B rests on and is supported by heel 3 in both the prior art shoe of Figure 8A and that of the present invention of Figure 8B.
