The CFS-300 shoes offer a new perspective on custom fit. Adaptive to any foot, a 100% heat moldable system is user-friendly and can be repetitively molded by conventional household means. Adjustable EVA foam padding is laterally and vertically adjustable with ratchet repositioning to optimize the fit. The HRS-100 System maintains heel positioning and offers a secure fit through a reinforced heel retention strap that integrates with the mid level strap. Two Coolmax Ergo Air insoles are provided to either allow through ventilation on hot days or block air on colder days. For the ultimate in power transfer, the shoe offers an Exo-Jet Carbon outsole with carbon molded arch support.
