Abstract

Described herein is a polyurethane foam produced in a “one shot process” that has low density, is semi-hard, and displays a high rebound value all while providing superior split tear performance. The polyurethane foam can be used in a “one shot process” to produce a shoe sole, a mid-sole or an insole for a shoe. The shoe sole may be used for forming an outer sole of a sandal type shoe, a midsole of an athletic type shoe, or an insole for insertion into any type of shoe.
