Definitions
- This invention relates to a new and improved design for high heeled pump or fashion shoes.
- the invention is particularly, though not exclusively, applicable to such shoes having heels in the height of at least one and three-quarter inches preferably in the range of one and three-quarters to two inches or more.
- Patent 2,465,817 in which, in the toe portion of the shoe, a concave depression 22 is arranged to receive the ball portion of the wearer's foot and a convex mound portion 24 is provided forward of that concave portion whereby the weight of the wearer is supported mainly, if not entirely, by the ball portion of the foot and by the heel of the foot with the wearer's weight mainly on the ball portion of the foot.
- Such an arrangement is said to permit very high heels, as high as four inches, without discomfort to the wearer as the ball portion of the foot is received n the concave depression of the shoe thereby preventing the foot from sliding forward in the shoe.
- the heel seat proposed in the construction disclosed is at a very substan ial angle to the ground plane, that angle being of the order of 45 degrees.
- very little of the wearer's weight will actually be supported by the heel seat with the wearer's weight, as stated above, being carried mainly on the ball portion of the foot.
- this design wi ll result in substantial discomfort and a reduction in foot flexibi lity.
- Other examDles of prior art wi ll be found in U.S.
- a comfortable high-heeled pump or fashion shoe capable of beirig used for extended periods without discomfort.
- a high heeled shoe defining ground plane and having a heel seat disposed at an angle of from approximately 0 degrees relative to said ground plane to an inclination upwardly and rearwardly of approximately 3 degrees relative to said ground plane.
- Figure 1 is a diagrammatic cross sectional view of a high heeled shoe according to the present invention.
- Figure 2 is a diagrammatic representation showing a comparison of relevant angles to the ground plane of a shoe according to the present invention such as that shown in Figure 1 and current high heeled shoes having similar heel heights.
- FIG. 1 With reference to Figure 1 there is shown in ghost the bone structure of a foot.
- This structure comprises the tarsus 1, the metatarsus 2 and the phalanges 3.
- the tarsus 1 is supported by the heel seat 4 whi le the metatarsus extends over the shank 5 to the ball of the foot 6 where the metatarsus joins the base of the phalanges 3.
- the ball of the foot underlying the heads of the metatarsals, forming the metatarsus, and the phalanges are supported by the toe region 7 of the shoe.
- the shoe illustrated in Figure 1 has a heel height of from approximately one and three-quarter inches to approximately two inches or more.
- the particular shoe i llustrated is based on a U.S. standard ladies' shoe size 7.
- the shoe is shown on a ground plane 8 from which the heel height to the heel seat 4 is measured.
- the heel seat 4 may be parallel with the ground plane or nclined uDwardly and rearwardly of the shoe at an angle of UD to approxi ately 3 degrees relative to the ground plane and is preferably at an upward and rearward inclination of approxi ately 2 degrees. This angle is referenced X in Figures 1 and 2.
- the metatarsus is angled downwardly and forwardly of the shoe from the heel seat with the first metatarsal at an angle of approximately 30 degrees plus/minus 3 degrees relative to the ground plane, preferably at an angle of approximately 30 degrees plus/minus 1 1/2 degrees and more preferably at an angle of approxi ately 30 degrees.
- This angle is reference Y in Figures 1 and 2.
- the great toe is inclined upwardly and forwardly by the upward and forward inclination of the toe region at an angle of approximately 5 1/2 degrees plus/minus 1 degree relative to the ground plane.
- This angle is reference Z in Figures 1 and 2.
- the line in ghost i llustrates the heel seat 4 angle X, the inclination Y of the first metatarsal 2 and the great toe spring Z in the toe region 7 relative to the ground plane 8.
- Dimension U represents the heel height.
- the solid line in Figure 2 represent the corresponding set of angles and inclination for currently avai lable high heeled shoes having similar heel heights to that proposed for the present invention.
- the foot is capable of functioning in two separate mechanical fashions so as to support the body above. Primarily, the foot functions as a beam and supports the body by bending strain. This mechanism of supoort is effective when the force in acting on the arch (arch flattening force) is relatively low. This occurs at such times in the step when the center of body weight falls posterior (behind) the ankle joint. As the center of weight passes ahead of the ankle joint, as occurs in a normal step forward, the forces present begin to cause arch flattening.
- the foot is capable of initiating a basic change in the mechanism of support to a truss form of support and is then capable of supporting via compression strain. Since the bones of the foot have been shown to be extremely strong in terms of compression strength, the greater the compression strain, the better the arch support abi lity. In order for the foot to achieve this change in support mechanism, the metatarsals must be buttressed by the bending of the toes. This buttress effect prevents the metatarsals from sliding forward and thus permits the switch from bending to compression supoort.
- Increasing the angle of bending (extension) of the toes in the shoes can be accomplished in one of two ways, the tip of the shoes may be lifted upwards creating a "genie" type shoe. Although this would be effective, it would not be particularly stylish.
- a more effective mechanism entails increasing the angle at which the metatarsals themselves approach the sole of the shoe. This has the effect of increasing the bending of the toes without creating a "genie" type shoe. This increase in the angle of the metatarsals relative to the ground plane is accomplished by the change in the rear construction of the shoe (specifically the angle of the heal seat 4).
- the heel seat is maintained essentially level (up to 3 ⁇ with respect to the ground irrespective of the heel height.
- the present invention creates a shoe with the relationship of the heel of the shoe parallel to the support surface.
- the metatarsal angle (corresponding to the shank of the shoe ) increases porporti ona I ly to the heel height, e.g. the higher the heel, the greater the metatarsal angle to the floor.
