I bought this for my father, but the size didn't fit, so I've been keeping it at home. Please ask if you have any questions. Sold as a single shoe. Velcro strap for easy on and off. Non-slip sole. If you need the small extension strap (20.5cm), I will include it for an additional 200 yen. Please let me know in the comments section. I will change the price. Retail price: 5390 yen (tax included) No returns accepted.
