I bought these for indoor use and wore them to the gym 2 or 3 times. I'm selling them because I stopped going to the gym. After returning from the gym, I immediately cleaned off any dirt and applied waterproof spray twice a week, about 2-3 times, to coat them. They've been stored with a desiccant inside. (The desiccant will not be included when shipped.) Thank you. I bought them for the retail price of 11,000 yen. Occasion: Running/Training Main Color: White Sneaker Type: Low-cut
