Merrell(R) Chameleon technology transforms these supportive sandals into easy-going slides with a quick switch of a strap. Lightweight, flexible nubuck leather strap uppers in an open-air design keep feet cool. Injection-molded thermoplastic urethane stability arms help lock heels into heel pockets for enhanced stability. Adjustable elastic-cord lacing with cordlocks cinch securely across insteps; Lycra(R) spandex/neoprene padded linings add comfort. Removable neoprene padded rear strap converts sandals effortlessly into easy-on slides. Removable anatomical footbeds add cushioning to In-Board(TM) compression-molded EVA midsoles. Air Cushion(R) heel pockets absorb excess shock from hard surfaces while injection-molded nylon arch shanks add stability on uneven ones. Vibram(R) Chameleon Sport(TM) outsoles feature Versa and TC1 Dura rubber for superior traction and durability on wet and dry surfaces.
