Abstract
A new design of shoe sole that includes both a base portion and a base support portion, wherein the base support portion is a base support portion attached underneath to the center area of the base portion. The current design further includes an expansion portion that extends downwardly from the outside rim of the base portion, wherein the expansion portion is elastic, and the bottom surface of the base support portion is higher than the bottom surface of the expansion portion. Footwear made of this type of sole first touch a support surface (ground) with the expansion portion, which forms a first contact region. Further because the expansion portion is located at the outward rim of the base portion, it is easier for the expansion portion to extend to all directions when pressed.
