Abstract: The present invention provides an improved shoe sole for a running shoe conducive to a midfoot striking gait including a cushioning element positioned between the upper surface and the ground-contacting surface, at least a portion of which is positioned on a lateral side of the sole and contained within a region between 15% and 90% of the length of the shoe sole as measured from a rearfoot end of the sole. One or more high abrasion-resistant ground-contacting crash pads are positioned below the cushioning element, and include a lateral side portion contained within a region extending a distance of 20% the length of the shoe sole, as measured from a rearfoot end of the shoe sole. The shoe sole, preferably devoid of at least vertical arch sculpting, also includes a longitudinal flex groove positioned just medial of the crash pads.

Abstract: An element forming at least part of a midsole for footwear includes a top portion, a bottom portion, and at least two strut members disposed between the top and bottom plates for supporting the top plate a distance away from the bottom plate. The top, bottom and struts may be formed of different materials. Adjacent strut members have a C shaped cross-section facing in the same direction when the midsole resting its top or bottom portion is viewed from the side. The midsole element may further comprise a heel cleft to increase the flexibility of the sole. In a preferred embodiment, the strut members on the medial side are arranged at an angle to the strut members on the lateral side of the sole. The directional design provides flexibility and stiffness anisotropically to the sole in the longitudinal and lateral directions of the sole respectively.
