Thank you for viewing. I am selling this because I no longer need it. Retail price: 2530 yen This item is new and unopened. Size: Compatible with sizes 25.0-26.0, and 3 sizes total. Can be cut to fit. The material is an insole made of "Sorbo-thane," an artificial muscle that is said to not break even if an egg is dropped on it. It evenly distributes pressure, is soft to the touch, absorbs impact from below, and smooths the movement of the center of gravity when walking. It will be wrapped in a waterproof poly bag and shipped in an envelope. Although it is new and unopened, it has been stored at home, so there may be some folds in the bag. Please understand this before purchasing.
