Splitting the difference between the Flatform Universal and the Original Universal, the Midform Universal is a people-pleaser. The rainbow upper, made from earth-friendly Unifi® Repreve recycled polyester webbing, is extremely durable and dries quickly after getting wet, whilst the Universal strapping system with its hook and loop fastening provides a secure fit and quick and easy on/off. 1 1/4" Lightweight EVA platform. Rubber outsole for durability and traction. Size US 5. New in box. Hard to find!
