Thank you for viewing! This is a health slipper from RIZAP. This slipper features a design with a raised toe, and by wearing and walking in it, you naturally balance your body. It's designed to help with core and abdominal muscle training, making it a product for diet and exercise. How about it for "while-you-do-it" dieting? RIZAP Slippers Size M Black & Charcoal Purchased from the co-op's mail order. Used indoors for about six months. Home cleaned. Stored at home for a while. Size M Advertised as 22-23cm. Adjustable foot thickness with the Velcro on the instep. Some signs of use. Some stains and scratches that couldn't be completely removed even after washing. Some wear on the soles. There are scratches from rubbing on the inside of the instep, which are not visible when worn (photos 13 and 15). Please understand that this is a used item. I plan to compress and pack it for shipping via Letter Pack Plus. It may become slightly wrinkled. #RIZAP #RIZAPSlippers #DietSlippers #Diet #WhileYouDoItDiet
