Two-sided zipper. This product allows for smooth putting on and taking off of the feet. This item was worn once for a short time for a photoshoot. It's made to be more relaxed than usual, and the soles of the shoes are not hard, providing a gentle feel. Please use this information as a reference. Color: Black This item is about 15,000 yen including tax. There are also new ones available, so please comment if interested. I think it feels the same as your usual shoe size.
