High heel shoe

Abstract

There are disclosed high heel shoes where separate components combine to create load balancing internal footwear technology. A two-piece system includes interlocking toe bed and shank constructed of complex three dimensional curved surfaces which create an intricately sculpted volume to provide structural support down the length of the entire foot. The toe bed provides a wide base and keeps the big toe pointed straight (at an approximately 10° angle). A heel maximizes the surface area of the bottom of the heel at the point of strike with the ground while retaining a minimal and aesthetically appealing silhouette from the side view. The toe bed and shank feature a composition of layered materials which when combined work to provide both stability and shock absorption to the ball of the foot during the foot strike of walking. An internal support structure provides a padded barrier and intermediary between the rigidity of the shank and the softness of the shoe upper.

AI Technical Summary

Benefits of technology

The patent text describes a method for making high heel shoes that are more comfortable and less painful to wear. The method involves adjusting the balance of the shoe by shifting the center of gravity of the body from back to front. This change of balance demands compensation in posture by other parts of the body, causing the knees to bend slightly forward and the hips and spinal cord out of alignment. The method also involves using a shank that bridges the outsole and heel, providing structural support to the foot and the weight of the wearer. The shank supports the foot and the weight of the wearer at the angled position of the shoe, creating the "lift" of a high heel. The patent text also describes various components of shoes, such as the upper, outsole, insole, and shank. The shoe can be open, closed, or partially open, depending on the coverage of the top of the foot.

Problems solved by technology

However, high heel shoes are typically not very comfortable and can cause pain in a wearer's foot when worn for prolonged periods of time.

This results in an increased amount of pressure on the ball of the foot rather than the heel bone.

However, inserts do not fit all shoe types and attempt to compensate for a poorly shaped shoe rather than correct the shoe itself.
