Description

  The present invention relates to a shoe whose heel is lifted high by a heel.

  The weight applied to the sole when a person walks is mainly applied to three places on the sole.

  FIG. 1 is a diagram for explaining which part of the sole is subject to weight when a person walks.

  FIG. 1 (a) shows a side view of a person's foot in a state where the sole is in contact with the ground from the inner foot side (first heel 91 side), and FIG. 1 shows a plan view showing the skeleton of the sole.

  Originally, when the entire sole of the person walking is grounded, the body weight is mainly near the rib 920, near the bone head 9111 of the first rib metatarsal 911, and the bone head 9151 of the fifth rib metatarsal 915. It takes 3 places with the neighborhood. In FIG. 1 (b), each of these three locations is circled. Here, the reason why no weight is applied in the vicinity of the metatarsal bone heads 9121, 9131, 9141 of the second to fourth toes 92 to 94 is that the metatarsals of normal human feet are arched. It is.

  FIG. 2 is a schematic view of a normal person's foot as viewed from the toe side.

  The portion of the metatarsal bone 910 of the foot 9 shown in FIG. 2 is arched (arc-shaped) in the direction W (the left-right direction in FIG. 2) of the heels 91 to 95, and the second heel 92 to the fourth heel 94. A gap S is formed between the metatarsal bone and the ground G.

  If weight is applied to the three places on the sole shown in FIG. 1 and then the advancement is continued, the weight is once applied to only one place in the vicinity of the rib 920, and thereafter, the first heel 91 and the second heel 92 are used. Advance by kicking the ground.

  However, in the women's shoes in which the heel is lifted by the heel, even if the entire sole is in contact with the ground, the higher the heel, the less likely the weight is applied to the vicinity of the rib 920, and the majority of the weight is the first heel. It comes to two places, near the metatarsal bone head 9111 and around the fifth heel metatarsal bone head 9151. When most of the body weight is applied to these two places, the skeleton of the foot is deformed while walking is repeated.

  FIG. 3 is a diagram schematically showing how the skeleton of the foot is deformed as a result of continuing to wear women's shoes whose heels are highly lifted by the heel.

  When walking is carried out in a state where most of the weight is applied to the first and second metatarsal heads 9111 and 9151, the middle shown in FIG. The arch shape of the foot bone 910 is crushed, and the metatarsal bone 910 ′ becomes a flat shape as shown in FIG. That is, the gap S shown in FIG. 2 is eliminated, and the metatarsals from the second heel 92 to the fourth heel 94 rather than the vicinity of the first heel metatarsal bone head 9111 and the vicinity of the fifth heel metatarsal bone head 9151. Most of the body weight is applied in the vicinity of the bone heads 9121, 9131, 9141 (see FIG. 1). When this happens, the ligaments connecting these metatarsal bone heads 9121, 9131, 9141 become expanded, and when walking in this state, these ligaments are further stretched by the impact applied each time they walk, or these The ligament is loaded and painful, making it difficult to walk for a long time. Further, in order to protect the metatarsal bone heads 9121, 9131, 9141 from the second to the fourth toes 94, which originally did not take weight, as shown in FIG. If a heel or stratum corneum layer 99 is formed on the skin of the sole that covers the bone heads 9121, 9131, 9141 from the lower side, and this heel or stratum corneum 99 is cracked, these also become painful every time they walk. It becomes difficult to walk for a long time.

By the way, in athletic shoes, mainly in sports competition, the lower surface side is considerably higher than the outsole in contact with the ground for the purpose of easily applying a load suitable for the sports competition or increasing the repulsive force. What provided the foam with thickness is known (for example, refer patent document 1 etc.).
JP 2007-1559597 A

  However, in the athletic shoe described in Patent Document 1, it may be easy to apply a load suitable for a sports competition, but the foam is under the first heel 91 and the second heel 92 that kick up the ground when moving forward. The force that kicks in and moves forward is attenuated by the foam and becomes unstable when walking. Moreover, shoes such as women's shoes whose heels are lifted high by the heel are unstable even when compared to athletic shoes, and thus further instability due to the foam is very problematic.

  In addition, many of the shoes that have high heels lifted by the heel do not have enough space above the bottom in the first place, and in such shoes it is important how to make your feet look elegant, Are often designed to look small. Therefore, it is impossible to provide a foam like a sports shoe described in Patent Document 1 on a shoe whose heel is lifted by a heel.

  In view of the above circumstances, the present invention relates to a shoe whose heel is lifted high by a heel, and can reduce foot pain without losing the design created so that the foot looks small, and can walk stably for a long time. It is intended.

The shoe of the present invention that solves the above-mentioned object is a shoe having a sole having a heel that touches the ground on the lower surface side and lifts the ribs from the height position of the metatarsal bone head by 30 mm or more.
The above-mentioned sole is a kick-up region in which a relatively hard tip portion extends from the joint front end to the toe of the metatarsal bone of the person wearing this shoe and the proximal phalanx of the rib that is in front of the metatarsal bone. It is located at the site that is directly below, and has a relatively soft impact absorbing member at the site that is directly below the load area that extends from the front end of the joint to the metatarsal bone head,
The impact absorbing member is fitted into a recess opened on the upper surface of the bottom.

  According to the shoe of the present invention, since the shock absorbing member is fitted in the recess provided on the outsole, the bottom of the shoe can be made thin so that the foot looks small. The impact-absorbing member can be provided without breaking down as much as possible. The shock absorbing member disperses and absorbs the shock applied to the vicinity of the metatarsal bone head. As a result, the foot pain is reduced in the shoe of the present invention, and the user can walk for a long time. Further, this shock absorbing member does not exist directly below the first and second kites that kick up the ground when moving forward, and the kick-up force by the first and second kites is the tip portion of the bottom base. Is transmitted firmly to the ground. Therefore, the shoes of the present invention can walk stably.

Further, in the shoe of the present invention, the outsole has a high repulsion member having a higher repulsive force than the outsole under the rib of the person who wears the shoe,
It is preferable that the high resilience member is fitted in a second recess opened in the upper surface of the bottom.

  The high resilience member is deformed so as to be crushed once by the weight applied to only one place near the ribs before being advanced by kicking the ground with the first and second scissors, but the deformed high resilience member Has a strong restoring force to return it to its original shape, and this restoring force assists the kicking of the ground by the first and second heels, making the foot less tired.

Furthermore, in the shoe of the present invention, an upper material that covers the foot of the person wearing the shoe,
An insole that contacts the soles of people wearing these shoes, and a sheet-like insole provided between the insole and the outsole, with the upper material pasted on the back,
In another preferred embodiment, the insole has a cutout hole located immediately above the impact absorbing member and a sheet member that closes the cutout hole and is softer than the insole.

  The insole is hard as it is because the upper material is attached to the back surface and fixed, and even when an impact absorbing member is provided on the bottom, the impact when the foot is grounded is It is bounced off by the insole and eventually becomes painful each time you walk. However, according to the above aspect, the impact when the foot is grounded is transmitted to the shock absorbing member provided on the outsole by the sheet member provided on the midsole, thereby reducing foot pain. In addition, the sheet member cooperates with the shock absorbing member to disperse and absorb the shock when the foot is grounded. Therefore, if the thickness of the shock absorbing member provided on the bottom is reduced by the thickness of the sheet member, the bottom can also be reduced, and the effect on the design created so that the feet look smaller can be reduced. Become. In addition, since the said sheet | seat member also does not exist under the 1st collar and the 2nd collar, the kicking-up force by the 1st collar and the 2nd collar is transmitted to the ground firmly.

  Furthermore, in the shoe of the present invention, it is also preferable to have a lateral arch support member that gradually rises upward from both ends toward the center in the lining direction of the heel under the load region.

  The metatarsal in a flat shape as shown in FIG. 3A is returned to the arch shape as shown in FIG. 2 by this lateral arch support member, and the expansion of the ligaments connecting the metatarsal bone head is eliminated. The pain of the foot is further reduced. Moreover, it can also be suppressed that the both sides of the foot (both sides in the lining direction of the heel) rub against the shoe and become painful due to the return to the arch shape.

  Here, the fact that the outsole has a ground and a height space of 15 mm or more on the front side of the heel leads to a design that makes the feet look smaller and more elegant. It is valid.

  ADVANTAGE OF THE INVENTION According to this invention, it is related to the shoes which a heel is lifted high, can reduce a foot pain, and can walk stably for a long time, without destroying the design created so that a leg may look small.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 4 is a side view of the outer foot side (fifth heel side) showing the women's shoes according to one embodiment of the present invention.

  A women's shoe 1 shown in FIG. 4 includes an upper material 10, an insole 20, an insole 30, and an outsole 40. The insole 20 is a sheet-like material cut in accordance with the shape of the entire sole, and the entire sole from the toe to the heel contacts. FIG. 4 is a perspective view so that the insole 20 can be seen and the internal structure of the outsole 40 can be seen.

  The upper material 10 is made of leather covering the legs, but in the women's shoes 1 shown in FIG. 4, the upper part is wide open to produce an elegant design. The upper material 10 is provided with a belt member 11 that is applied to the ankle. Moreover, in the women's shoes 1 shown in FIG. 4, what is called a cement system is employ | adopted, and the upper raw material 10 is affixed on the back surface of the insole 30, and is being fixed.

  FIG. 5 is a bottom view showing the back surface of the midsole shown in FIG.

  As shown in FIG. 5, the insole 30 is also cut according to the shape of the entire sole in the same manner as the insole 20. The upper material 10 is affixed over the entire outer edge of the back surface 30a of the midsole 30. The insole 30 is affixed to the bottom 40 shown in FIG. 4, and the insole 20 is affixed to the insole 30 via a sponge sheet to be described later. And the outsole 40 is integrated.

  FIG. 6 is an exploded perspective view before the insole, the insole, and the outsole are integrated.

  As shown in FIG. 6, the insole 30 has a sheet shape. More specifically, the insole 30 shown here is made of cardboard having a thickness of 0.8 mm or more and 5 mm or less, but is not limited thereto. The hardness of the insole 30 is 45 or more when measured using a spring-type hardness meter (JIS-A type) defined in JIS K6301-1975. Hereinafter, the hardness is a value when measured using the spring type hardness meter.

  Further, the bottom 40 is made of urethane molded in accordance with the shape of the entire sole, and the hardness thereof is 45 or more. The bottom 40 is in contact with the ground on the lower surface 400 side. In the bottom 40 shown here, the heel 41 is integrally provided on the lower side 400 side and below the ribs. However, the heel may be provided separately as a separate body. As shown in FIG. 4, the heel 41 lifts the ribs by 30 mm or more from the height position of the metatarsal bone head of the person who wears the shoes. The main bottom 40 has a ground and a height space of 15 mm or more on the front side (toe side) of the heel 41. In the women's shoe 1 shown in FIG. 4, the heel 41 is provided so that the heel is lifted high, and the portion 401 under the metatarsal bone head is grounded, but under the arch behind it. The part 402 is provided with a large space between itself and the ground so that the feet can be seen small. Further, the heel 41 has a urethane lift 411 in which a rubber 4111 for preventing slippage is fitted at the bottom at the grounding portion. The anti-slip rubber 42 is also fitted into a portion 401 below the metatarsal bone head. Further, in order to increase the strength, a heel 41 is provided with a core material 412 made of ABS (Acrylonitrile Butadiene Styrene) resin, and a metal shank 43 extends forward from the core material 412.

  As shown in FIG. 6, a rib 44 that rises as much as the thickness of the midsole 30 is provided on the entire upper surface 40 a of the main bottom 40 to which the midsole 30 is bonded. The shape of the region surrounded by the ribs 44 matches the shape of the midsole 30, and the midsole 30 is fitted into the region surrounded by the ribs 44 and bonded to the upper surface 40 a of the outsole 40. .

  FIG. 7 is a plan view showing the skeleton of the sole.

The 7, Keage regions S _k and load area S _l is shown in the sole of the human. Keage regions _{S k} includes a metatarsal 910, a region extending from the front end 9401 to toe 90t of the joint 940 of the proximal phalanx 901 of the phalanges 90 made on the front side than the metatarsal 910, the left in FIG. 7 This is a region indicated by a downward slanting line. On the other hand, load area S _l, the an area that extends over the metatarsals bones head 9101 from the joint front 9401, a region indicated by downward-sloping diagonal lines in FIG.

The bottom 40 shown in FIG. 6 is provided with two concave portions opened on the upper surface 40a. That is, the position where just below the load area S _l shown in FIG. 7, the recess 45 that opens upward is provided, a second recess opened again upward to a position to be below the calcaneus 920 46 is provided. The recess 45 beneath load area S _l is shock absorbing sponge 47 corresponds to an example of the shock absorbing member according to the present invention is fitted. The shock absorbing sponge 47 is softer than the bottom 40 and has a hardness of 10 or more and 30 or less. As the shock absorbing sponge 47, for example, a foam made of a synthetic resin foam such as urethane or rubber can be used. The shock absorbing member referred to in the present invention does not necessarily have a sponge shape. In FIG. 7, the position of the shock absorbing sponge 47 on the sole of the person wearing the women's shoes 1 is indicated by a one-dot chain line. Shock absorbing sponge 47 is present so as to extend rearward from beneath the load area S _l, absent beneath the Keage regions S _k. Directly below Keage regions S _k, the distal end portion 40t of the bottom 40 there is harder than the shock-absorbing sponge 47.

  Further, in the second recess 46 just below the rib 920, a high resilience sponge 48 corresponding to an example of a high resilience member according to the present invention is fitted. The high resilience sponge 48 has a resilience higher than that of the bottom 40 and has a hardness of 10 to 30. As the material of the high resilience sponge 48, a synthetic resin foam having high resilience elasticity can be used. The high resilience member referred to in the present invention does not necessarily have a sponge shape.

  Here, when the shock absorbing sponge 47 and the high resilience sponge 48 are compared, as can be seen by dropping a small lead ball on these sponges 47, 48, the lead ball hardly rebounds in the shock absorbing sponge 47. On the other hand, in the high resilience sponge 48, the lead ball rebounds firmly. In both sponges 47 and 48, the place where the lead ball fell is once depressed and then restored to its original shape. In general, the high resilience sponge 48 has a faster restoration speed than the shock absorbing sponge 47, but the shock absorbing sponge 47 may have a relatively high restoration speed while giving priority to the shock absorbing characteristics. Alternatively, a laminate having a relatively high restoration speed and a relatively slow restoration speed may be bonded together to form a laminated structure, and may be fitted into the recess 45 so that a lower restoration speed is present on the lower side. . Furthermore, the same sponge as the high resilience sponge 48 may be disposed under the shock absorbing sponge 47.

Further, even if the recess 45 directly below Keage regions _{S k,} also in the second recess 46 beneath the calcaneus 920, front walls 451, 461 and the rear of the walls defining these recesses 45, 46 The walls 452 and 462 are inclined so that the opening area becomes smaller as going downward. That is, the front walls 451 and 461 are inclined toward the rear side, and the rear walls 452 and 462 are inclined toward the front side. Further, in both the shock absorbing sponge 47 and the high resilience sponge 48 fitted in the recesses 45 and 46, the front end surfaces 471 and 481 are inclined rearward so as to match the inclination of the front walls 451 and 461. The rear end surfaces 472 and 482 are inclined forward so as to coincide with the rear walls 452 and 462. For this reason, both the shock absorbing sponge 47 and the high resilience sponge 48 are thinner at the front end toward the front side and are thinner at the rear end toward the rear side. This is to make it difficult for a person who wears the women's shoes 1 to feel the difference between the hardness of the shock absorbing sponge 47 and the high resilience sponge 48 fitted in the recesses 45 and 46 and the hardness of the outsole 40. . That is, the hardness is prevented from abruptly changing at the front edge and the rear edge of the recesses 45, 46, and the front walls 451, 461 in the bottom 40 are directed to the front side. This is because it gradually becomes harder and gradually becomes harder toward the rear side in the portions of the rear walls 452 and 462.

As shown in FIGS. 5 and 6, the midsole 30 is provided with two cutout holes, a cutout hole 31 and a second cutout hole 32. The cutout hole 31 shown in FIG. 6 is located immediately above the shock absorbing sponge 47 and is closed by the shock absorbing sheet 33 corresponding to an example of the shock absorbing member according to the present invention. The shock absorbing sheet 33 is softer than the insole 30 and has a hardness of 10 or more and 30 or less. As the shock absorbing sheet 33, for example, a sheet made of a synthetic resin such as urethane or rubber can be used. Moreover, the thickness of the shock absorbing sheet 33 is equal to the thickness of the midsole 30. Cut-out hole 31 is a hole that has been cut out along the opening edge 451 of the recess 45 directly below Keage regions S _k. Therefore, when the midsole 30 is bonded to the bottom bottom surface 40a, the edge 31a of the cutout hole 31 of the midsole 30 coincides with the opening edge 45a of the recess 45 of the bottom 40, and the shock absorbing sheet 33 is also shocked. as with absorption sponge 47 not present just below the Keage regions S _k shown in FIG. 7, the distal end portion 30t of the insole 30 is present beneath the Keage regions S _k. Moreover, even if the shoe has the insole 30 having a hardness value of 45 or more as in the present embodiment, the impact absorbing sheet 33 causes the impact when the foot is grounded to be provided on the outsole 40. It is reliably transmitted to the absorption sponge 47. It should be noted that the cutout hole 31 only needs to be located directly above the shock absorbing sponge 47, so long as it does not enter the tip portion 30t of the midsole 30 and the shock when the foot is grounded is transmitted to the shock absorbing sponge 47. The size of the cutout hole may be larger or smaller than the recess 45. On the other hand, the second cutout hole 32 is located immediately above the high-repulsion sponge 48 and is blocked by the high-repulsion sheet 34. The high resilience sheet 34 is also softer than the midsole 30 and has a hardness of 10 or more and 30 or less. As the high resilience sheet 34, for example, a sheet made of a synthetic resin having high resilience elasticity can be used. Further, the thickness of the high resilience sheet 34 is the same as the thickness of the midsole 30 like the shock absorbing sheet 33.

Further, as shown in FIG. 6, a sponge sheet 35 (not shown in FIG. 4) is interposed between the insole 20 and the insole 30. In the sponge sheet 35, a lateral arch support member 351 is provided at a site under the metatarsal 910 shown in FIG. 7, and a latex pad 352 is provided at a site under the rib 920. The lateral arch support member 351 provided under the metatarsal 910 is below the load region S ₁ extending from the joint front end 9401 between the metatarsal 910 and the proximal phalange 901 of the radius 90 to the metatarsal bone head 9101. Compared to the provided shock absorbing sheet 33 and shock absorbing sponge 47, it is located somewhat behind. Both the horizontal arch support member 351 and the latex pad 352 are rich in elasticity, and both have shapes that gradually rise upward from both ends toward the center of the wrinkle arrangement direction W (see FIG. 2). The lateral arch support member 351 is about 20-30% thicker at the thickest part at the center than at both ends. Furthermore, the horizontal arch support member 351 has a shape that gradually rises from the front side (toe side) to the rear side (heel side) toward the center in the front-rear direction.

  8 is a plan view of the bottom shown in FIG. 4 as seen from directly above, and FIG. 9 is a cross-sectional view including the A-A ′ cross-sectional view of FIG. 10.

In Figure 8, provided on the upper surface 40a of the bottom 40, a second recess 46 beneath the recess 45 and the calcaneus 920 beneath load area _{S l} is shown. Further, in FIG. 9, the shock-absorbing sponge 47 is shown above the load area S _l recess 45 beneath. Further, an insole 30 and a sponge sheet 35 are also shown above the shock absorbing sponge 47. Although FIG. 9 is a cross-sectional view, hatching is omitted.

As particularly clearly shown in FIG. 9, the wall 453 on the inner foot side (first heel side) among the walls that define the recess 45 _immediately below the load region S ₁ has an inverted “<” shape in cross section. The recessed portion 45 is provided with an overhanging space R that projects to the inner foot side from the opening edge 45a. On the other hand, the outer foot side wall 454 is a vertical wall. Also, the end surface 473 on the inner foot side and the end surface 474 on the outer foot side of the shock absorbing sponge 47 are vertical surfaces. The weight of the person wearing the women's shoes 1 is more likely to be applied to the inner foot side compared to the inner foot side and the outer foot side, and particularly on the inner foot side, the hardness of the shock absorbing sponge 47 and the hardness of the outsole 40 are particularly high. It is easy to feel the difference. As shown in FIG. 9, the edge 45i of the recess 45 on the inner foot side becomes thinner as it approaches the housing space 45r in which the shock absorbing sponge 47 is housed. For this reason, the hardness of the edge portion 45i on the inner foot side becomes softer as it approaches the shock absorbing sponge 47, and further, the edge portion 45i on the inner foot side can be bent toward the overhanging space R side. It is. Accordingly, the hardness is prevented from changing suddenly at the inner leg side edge of the recess 45, and the person wearing the women's shoes 1 is different from the hardness of the shock absorbing sponge 47 and the hardness of the outsole 40. Is hard to feel even on the inner foot side. In addition, as shown by a two-dot chain line in FIG. 9, the wall 453 on the inner foot side having an inverted “<” shape in cross section is directed toward the outer foot side so that the opening area becomes smaller as it goes downward. The end surface 473 on the inner foot side of the shock absorbing sponge 47 may be inclined so as to coincide with the inclination as indicated by a two-dot chain line. Further, if importance is attached to the ease of processing, the wall 453 on the inner foot side having a reverse “<” shape in cross section may be a vertical wall in the same manner as the wall 454 on the outer foot side. .

Further, the depth D (see FIG. 9) of the recess 45 _immediately below the load region S1 is 5 mm or more and 9 mm or less, and the shock absorbing sponge 47 has a thickness corresponding to the depth D of the recess 45.

  The women's shoe 1 shown in FIG. 4 has an insole in which the upper material 10 is pasted on the back surface 30a, the cutout hole 31 is closed with the impact absorbing sheet 33, and the second cutout hole 32 is also closed with the high repulsion sheet 34. 30 and the bottom 40 in which the shock absorbing sponge 47 is fitted in the recess 45 and the high-repulsion sponge 48 is fitted in the second recess 46 are bonded together, and further, the sponge sheet 35 is interposed on the inner bottom 30. The insole 20 is attached to complete. In the completed women's shoes 1, the heel 41 lifts the heel high, so that most of the weight of the person wearing the women's shoes 1 is near the first heel metatarsal head and the fifth heel metatarsal. It comes to two places near the bone head. However, according to the women's shoes 1, the impact when the foot is grounded is reliably transmitted to the shock absorbing sponge 47 through the shock absorbing sheet 33 provided on the insole 30. The shock absorbing sponge 47 disperses and absorbs the shock applied to the vicinity of the metatarsal bone head 910 in cooperation with the shock absorbing sheet 33, so that the foot pain is reduced and the user can walk for a long time. In addition, since the shock absorbing sponge 47 is fitted in the recess 45 provided on the bottom 40, the bottom of the shoe can be made thin, and the effect on the design created so that the foot looks smaller. Is small. Further, neither the shock absorbing sponge 47 nor the shock absorbing sheet 33 is present immediately below the first and second kites that kick up the ground when moving forward, and is kicked up by the first and second kites. The force is firmly transmitted to the ground by the tip portion 30t of the insole 30 and the tip portion 40t of the outsole 40. Therefore, the women's shoes 1 can walk stably.

  In addition, the high resilience sheet 34 and the high resilience sponge 48 just below the rib 920 are once crushed by the weight applied to only one place near the rib 920 before moving forward by kicking the ground with the first and second kites. The high resilience sheet 34 and the high resilience sponge 48 thus deformed have a strong restoring force to return to the original shape, and this restoring force causes the ground to kick out by the first and second rods. In the women's shoes 1 shown in FIG. In addition, the impact applied to one place near the rib 920 is absorbed by the latex pad 352 provided on the sponge sheet 35.

  Further, the metatarsal bone having a flat shape as shown in FIG. 3A is returned to the arch shape as shown in FIG. 2 by the lateral arch support member 351 provided on the sponge sheet 35, and the metatarsal bone is restored. The spread of the ligament that connects the bone head is eliminated, and foot pain is further reduced. Further, in the metatarsals that have a flat shape, the width of the foot (the length in the heel alignment direction W) is widened, and the outside of the first heel metatarsal bone head 9111 shown in FIG. The both side portions 96 and 97 (see FIG. 7) of the foot outside the ankle bone head 9151 rub against the upper material 10 and become painful, but the width of the foot becomes narrower by returning to the arch shape, and both sides of the foot It is also possible to prevent 96 and 97 from rubbing against the upper material 10 and becoming painful.

  As described above, according to the present embodiment, in the women's shoes 1 in which the heel is lifted high, the foot pain is reduced without breaking the design as much as possible so that the feet look small and stable for a long time. Can walk.

It is a figure for demonstrating which part of a sole takes weight when a person walks. It is a schematic diagram when a normal human leg is viewed from the heel side.
