These are Vibram FiveFingers five-finger shoes. Size: Approximately 26.5cm I used them at the gym for about 2 years. They have been cleaned. I haven't worn them outdoors, so there is little wear on the soles. Although there is some feeling of use, I didn't see any noticeable scratches or scuffs. [Brand Description] Five-finger shoes developed by Vibram, an Italian sole manufacturer boasting the world's best quality. They allow your toes to move freely and enable the natural movement of your feet, providing an open and comfortable feel that teaches us the "natural state" of our bodies.
