These are unique room shoes registered as general medical devices. I'm selling them because I accidentally bought the wrong size. They are size XS, but fit 22-23.5cm, so they should fit a wide range of people. Made by an insole manufacturer, they are very comfortable to wear. The instep can be adjusted with Velcro, so they fit various feet. They also provide good support for the arch of the foot. Since I started using these room shoes, my feet have become very comfortable, and I can't wear anything else. They are recommended for elderly people concerned about their legs and lower back, as well as for younger people as recovery sandals. Available for immediate purchase. Black quilted design slippers, made of synthetic fiber for comfortable wear. - Color: Black - Design: Quilted design - Material: Synthetic fiber - Sole: Rubber sole - Accessories: Comes with original box Thank you for looking.
