  • Performance enhancing shoe components and methods
    Patent number: 6589630
    Abstract: The present invention provides performance enhancing shoe components and methods of using those shoe components to increase exercise performance. The shoe components comprise a layer of 1,4-polybutadiene and, optionally, a high energy returning rubber. A second layer of an energy returning rubber and/or a coating is optionally applied to the first layer. The invented shoe components may be formed as shoe inserts, insoles, midsoles, soles, or portions thereof.

  • Performance enhancing athletic shoe components and methods
    Patent number: 6120880
    Abstract: The present invention provides performance enhancing shoe components. The invented shoe component includes an upper layer of 1,4-polybutadiene and, optionally, a rubber such as natural rubber, synthetic isoprene rubber or polyisoprene. The first layer is attached to a resilient layer which extends substantially the length of the shoe. Optionally, a third layer or a coating may be attached to the resilient layer. The invented shoe components may be formed as shoe inserts, insoles, midsoles or shoe soles.
