Abstract

Footwear upper, at least part of which has a cracking-resistant flexible outer layer based on an elastomer blend produced by curing a curable composition comprising a blend of natural rubber and EFDM. A preferred blend comprises highly unsaturated EPDM and high polyisoprene natural rubber in a ratio of about 30:70 by weight.
