I only tried these on indoors, but the size doesn't fit, so I'm listing them for sale. I repurchased a different size, and they seem soft, fit the foot well, and are easy to wear ◎ ※ 16.5cm ※ The second and subsequent photos appear slightly brighter; the first photo is the closest to the actual color. ※ Due to the manufacturing process, there may be some burrs, but this is not a defect (see photo 4).
