Abstract
A shoe insole (or sole) includes at least two elastomeric pads horizontally distinct from one another, each pad having a different rebound rate. The insole thereby provides at least one pad with relatively greater shock absorbing properties and at least one other pad with relatively greater energy return, or lift, properties. These differing characteristics allow an insole to be customized with regard to the specific use of a shoe.
