Used only once indoors for rehabilitation. It's a good product, but there is a mark where a name was erased on the back of the heel. Please refrain from purchasing if you are overly concerned about this. Additional shipping charges apply to Hokkaido, Okinawa, Tohoku, and remote islands. Shipped via Sagawa Express. No time-wasters or "likes" without intent to purchase. Please set a time limit for your "likes."
