ABSTRACT:
The present invention provides performance enhancing shoe components, and methods of making the same, comprising 1,4-polybutadiene and a rubber selected from the group consisting of natural rubber, synthetic isoprene rubber, polyisoprene, butadiene acrylonitrile rubber and ethylenepropylene diene modified rubber. The shoe components are most advantageously placed in the user shoe beneath the ball of the foot to increase energy return and thereby enhance athletic performance. The shoe components may be formed as midsoles and parts of midsoles, insoles and parts of insoles, or shoe inserts.
