Abstract
Abstract A shoe containing a plurality of pairs of transverse 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 and then the ribs are compressed. The ribs begin to become compressed when one of each pair of the ribs would intrude upon an adjacent rib of a second pair of ribs.
