MedSpec XS size 22-23.5 cm This is an ankle support prescribed by a hospital. It was purchased at the hospital for about 10,000 yen. My child used it a few times for about 3 weeks after injuring their ankle. It can firmly protect the ankle because it is secured with Velcro straps from various directions. There are no noticeable scratches or stains, and it can be used without any problems, but please refrain from purchasing if you are sensitive to used items. Size: XS (SS) #Ankle Brace (MS)
