The materials of the Hydro Next Gen sandals do not absorb water; you simply shake off the water droplets after coming out of the water. A great choice for use in many water sports, for wading, and as a supple shoe for camp use. Unlike some similar types of sandals, Merrell's Hydro Next Gen sandals utilize different materials in various parts. The result is a sturdier sandal that still offers heel cushioning. The heel on this Next Gen model is more supportive than the one in the original. - Standard fit - FloatMax midsole for cushion - Rubber outsole - The sandals' Bloom foam is made of algae-based fiber
