Brand new, unused item. I purchased multiple items at an event, so I am listing this one. Includes instruction manual. Below is a summary of the instruction manual: In modern times, where the feet are not able to fully utilize their function due to environments that don't allow for various uneven surfaces (for gripping with the feet), it is said that the decline in muscle strength and limitations in range of motion, along with the loss of the normal arch function of the foot, lead to various foot problems. When the normal arch of the foot is lost, other parts of the body also become distorted and affected. 〇 For those who don't have time to exercise and find it difficult to start, we especially recommend Ashinazori (foot-half sandals) as room shoes, as they "exercise your feet just by wearing them." No claims, no returns. #DietSlippers #ClothZori
