I purchased these last year and wore them a couple of times, but they didn't fit my feet, so I'm selling them. The size is 27cm. ◆ Durable Rubber Sole The outsole is made of rubber, featuring a design that provides good grip and water drainage. In addition, the design focuses on both grip and lightness, with no midsole to shorten the distance to the ground. The upper part is made of mesh material, which provides good breathability and water drainage, and dries easily, making it less likely to cause blisters or chafing when your feet get wet. The sole has a back strap for long-term use and safety, and a Velcro closure for easy on and off, making it a highly anticipated model. ◆ Over 3.88 million insoles sold* The insole that directly touches the foot feels good against the skin, and the cushioning sole that supports it is excellent in shock absorption and durability, and the outsole boasts excellent grip. This three-dimensional shape and four-layer structure is what makes it a recovery shoe.
