Abstract
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.

Claim 1
Independent Claim
175 words
A sole component for a shoe comprising: an inner sole provided directly underneath the shoe; a mid-sole provided directly underneath said inner sole, said mid-sole provided with a plurality of pairs of parallel ribs each of said pairs of ribs provided with first and second ribs, said first rib of one of said pairs of ribs provided with at least one portion angled with respect to said inner sole, and said second rib of said one of said pairs of ribs provided with at least one portion angled with respect to said inner sole and angled oppositely from said angled portion of said first rib, each of said pairs of ribs initially spaced from adjacent pairs of ribs such that when a force is applied normal to said shoe, each of said ribs freely deflects until each of said first ribs of said pairs of ribs intrudes upon a second rib of an adjacent pair of said ribs, at which point said ribs begin to compress; and an outer sole provided directly underneath said mid-sole.
