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.
  • US 2009/193683 discloses a flexible contoured footbed insole for footwear for providing an anatomically correct foot support to a wearer of the footwear.
  • the flexible contoured footbed insole comprises a heel section and a support system extending anteriorly from the heel section.
  • the heel section comprises a cup shaped structure for accommodating a heel of a foot of the wearer.
  • the support system comprises an inner longitudinal arch support, an outer longitudinal arch support, a transverse arch support, a metatarsal arch support, and a toe support for supporting an inner longitudinal arch, an outer longitudinal arch, a transverse arch, a metatarsal arch, and toes of the foot of the wearer respectively.
  • the flexible contoured footbed insole may further comprise a flexible structure disposed within the support system.
  • US 5782 015 describes a high-heel shoe design applicable to varying heel heights.
  • Shoes and particularly those known as high-heeled shoes, generally exceeding 50.8 mm (2 inches), are adapted to be worn on a human foot. Though comfort is a primary consideration of footwear, it is often secondary to style, particularly with respect to the aforementioned high-heel shoes, which are most often specifically worn because of style considerations.
  • the human foot is comprised of twenty six different bones, which are connected to each other by approximately thirty joints and held in their respective places by ligaments and joint capsules. Thirty tendons, in addition to the lower muscles of the leg and the tendons of the foot muscles, have a role in foot movement.
  • the ankle joint is responsible for the dorsiflexion (raising the toes and standing only on the heels) and plantarflexion (lowering the toes and standing only on the toes) movements of the feet.
  • tarsal bones there are five bones called tarsal bones, and these bones may become a very resistant or rigid structure, when necessary, by movement as a group, depending on the nature of the surface, which they are in contact, via the joints there between.
  • the tarsal bones are the five long bones, which are located at the front part of the foot.
  • knuckles which consist of phalanxes, required for normal walking.
  • the toes are connected with the tarsal bones via metatarsophalangeal (MTP) joints with the most important one being the first MTP joint, belonging to the big toe.
  • MTP metatarsophalangeal
  • 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 (cuboid bone and three cuneiform bones). Five toes comprise the third or front part of the foot. The big toe has two phalanxes just like the thumb of a hand and the other toes have three phalanxes. When a load is exerted on the toes, during a time when the big toe presses the ground, the other four toes assume a grabbing movement positioning.
  • 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 50.8 mm (two inches) configured with component elements in an interrelational 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.
  • insole board refers specifically to the portion of the shoe and curvature thereof, which directly supports and is in contact with the wearer's foot. It also includes the same type of upper structure in a wedge type high-heeled shoe.
  • the insole board of a high-heeled shoe generally follows a shape similar to an arctan (k*x) function.
  • 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 " / 1 + y ′ 2 3 / 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.
  • Equation 3 The form of equation 2 for the K value expressed in terms of values for x and the constant k is shown as "equation 3" which equation is used for the determined curvature.
  • K ⁇ 2 k 3 x . 5 / arctan 10 k . 1 + k 2 x 2 ⁇ 2 1 + k 2 . 5 / arctan 10 k 2 . 1 + k 2 x 2 ⁇ 2 ⁇ 3 / 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:
  • Table 1 shows the sole alignments (x values) where the greatest "curvature” takes place by using equation 4 is as follows:
  • variable x j for the heel sizes of A 1 , A 2 , A 3 , A 4 , A 5 , A 6 are given in Table 4 below, with: x 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.
  • 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.
  • the A 2 , A 3 , A 4 , A 5 , and A 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.
  • Table 2 shows that A 1 , A 2 , A 3 , A 4 , A 5 , and A 6 inboard soles can be produced in high heeled shoes without front platforms, with a height ranging from about 50.8 mm (2") to 114.3 mm (4.5") and as high heeled shoes, with appropriately sized front platforms with a height ranging from about 0 mm (0") to 76.2 mm (3.5") provided that the elevation distance between the front of the foot wearing the shoe to the heel is no more than about 114.3 mm (4.5"), i.e. with appropriate platforms ranging from 0 mm (0") to 76.2 mm (3.5") for the aforementioned heels.
  • the high heeled shoes (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.
  • shoe heels that range from 50.8 mm (2 inches) to about 203.2 mm (8 inches) preferably have ( ⁇ ) heel angle values in the range of about 5° to 26° (with a 10% possible deviation) as shown in Figure 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 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.
  • 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.
  • 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.
  • the degree curve value for A 1 can range from 42.96° to the 45.63° of A 2 .
  • the value ranges from 42.96° of A 1 to the 49.61° of A 3 from the values of A 1 to A 3 .
  • a 3 the value ranges from the 45.63° of A 2 to the 51.72° of A 4 and for A 4 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 A 1 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 A 1 to A 6 as given in the table for the specific heel heights with heels angles for A 1 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 A 1 and A 6 being respective minimums and maximums (with possible deviations of up to 10%).
  • the x j and k values of Table 4 are used to provide the extrapolation of range values between the adjacent A 1 to A 6 values.
  • modelling 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 1 - 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 8A 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 .
  • the heel angle ( ⁇ ) of the shoes of the present invention, shown in Figure 2 and Figure 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 Figure 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.
  • 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 Figure 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 Figure 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.
