A compound formulation having good abrasion resistance and flex crack resistance was developed for a combat boot outsole. The lightweight polyurethane has a specific gravity of 0.55. To fabricate the outsole, liquid injection molding equipment was used. In an attempt to improve flex cracking resistance a modified chevron outsole was designed. To facilitate quality control, a Polyair flex tester was evaluated.
