1. A footwear sole system comprising
a) a sole having two or more layers wherein a first sole layer has an outer bottom surface configured to contact a ground surface and an inner upper surface bonded to a bottommost surface of an inner sole layer and a second sole layer has a top surface configured to contact the bottom surface of a first insole layer and a bottom inner surface bonded to a topmost surface of an inner sole layer, wherein an inner sole layer is molded in a manner able to convey information when the bottom surface of the inner sole layer is exposed by degradation of the first sole layer; and b) an insole having two or more layers wherein the first insole layer has a top surface bonded to a bottommost surface of an inner insole layer, and a second insole layer has a top surface configured to contact a user's foot and bottom surface bonded to a topmost surface of an inner insole layer, wherein the topmost inner insole layer is molded in a manner such that information is conveyed to the user when the second insole layer is degraded by friction to expose the inner insole layer.
