Embodiment Construction

[0029]In order to properly understand the invention, prior art shoes must be examined, specifically, the pressure on the bottom of the foot due to the footstrike pattern induced by the shoe. FIG. 1 shows the pressure on the bottom of the feet 100 during the footstrike. The bottom of the feet 100 contains individual circles 104. Each individual circle 104 represents pressure on the bottom of the feet 100. The darker the circle, the greater the pressure. The lines 102 show the direction of the movement of the center of pressure which begins in the heel region 110 and progresses towards the mid-foot region 108 and then moves to the forefoot region 106.

[0030]FIG. 1A is a depiction of how the footstrike occurs in a prior art shoe. The heel region 110 has a relatively large angle formed by the intersection of a longitudinal line from heel to toe and the ground. The shoe touches the ground 130 first in the heel region 110, then in the mid-foot region 108, and finally in the forefoot region...

Abstract

A shoe with a curved rocker bottom sole member with an H-shaped pad that is decoupled from the sole member. The shoe promotes a mid-foot region footstrike and a more even distribution of pressure.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to athletic shoes and, in particular, a shoe that provides more efficient and natural running by promoting a mid-foot region—rather than a heel region—footstrike (i.e., the place where the foot first strikes the ground during the gait cycle) and a more even distribution of pressure which, in turn, leads to greater running efficiency. All of this is achieved by combining a rocker bottom curved sole member with an H-shaped pad which is placed within, but decoupled from, the sole member.[0003]2. Description of Related Art[0004]Prior art shoes have encouraged users to land on their heels first and transition to their toes during running, thereby putting the center of pressure and thus the most pressure and load on the heel region of the foot when it first strikes the ground. That is not the most efficient or natural motion for running Striking in the heel region of the foot leads to poor shock ...
