Abstract

A shoe has an upper and a sole including a member having a top wall with a lower surface. The member has a bottom wall with an upper surface. The bottom wall has at least two portions approximately planer with each other, parallel with the ground, and separated by a gap therebetween. The top wall and the bottom wall each are connected at a closed end by a curved wall proximate the mid-foot region of the shoe. The top, bottom, and curved walls are integral. The top and bottom walls are spaced a distance from each other so that during the wearer's gait cycle when the shoe is in contact with the ground the predetermined distance is reduced. The sole includes at least one element positioned between the top wall and the bottom wall. The element has an interior sidewall. A void is located beneath the lower surface of the top wall and above the upper surface of the bottom wall and defined at least in part by the interior sidewall of the element. At least one opening is in communication with the vold on at least one of the medial and lateral sides of the shoe. The sole includes a bottom surface that is at least in part ground-engaging.
