Teva - Ultimate Thong (Copen Blue) - Men's: Flat out the best flip-flop ever made. Designed in the Grand Canyon, worn on rivers and beaches around the world. Three-point upper with instep retention strap. Soft, tubular nylon webbing. Compression molded rubber topsole. Injection molded polyurethane midsole. Encapsulated Shoc Pad features a blended polyurethane/EVA unit in the heel cup that evenly transfers the energy of impact throughout the footbed and away from the heel. This energy return actually provides greater spring with each forefoot push-off. Original, resolable, non-marking Spider Rubber outsole performs exceptionally well on wet and dry terrain.
