Waterproof and lightweight, these flip flops for men and women are perfect for the beach, the pool, knocking around town or just puttering about the house. This unisex footwear is durable, comfortable and non-skid, thanks to its EVA outsole. EVA is a durable, non-toxic material that's one of the most efficient shock absorption materials on the footwear market today. It's a favorite among manufacturers of jogging and running shoes. The EVA outsoles on these unisex flip flops are a closed cell structure which is non-absorbent. That means it won't retain any odors and is a breeze to clean.
