Abstract
A shoe containing a plurality of pairs of ribs provided between the mid-sole and the outer sole. All of the ribs are provided with at least one bowed or convex surface running the length of the rib. When weight is placed upon the sole, each of the ribs initially begins to deflect until adjacent ribs abut one another at which point the ribs begin to compress. Additionally, an elastic bridging element is provided between each of the ribs provided in a single pair of ribs.
