The design is inspired by the Japanese custom of wrapping items in cloth fabric. The shoes feature a unique sole that wraps around the entire foot, secured by a hook-and-loop (Velcro) system. The upper material is a flexible, 4-way stretch fabric, often made from recycled materials in the EcoFree version. They are known for being minimalist and flexible, feeling more like a sock than a traditional shoe. In good condition, with some signs of wear but overall good condition.
