- Material: Washable, reusable - Use: Shoe insoles These are squishy, cushioned insoles. Thank you for looking. I bought these for use at Universal Studios Japan, but I accidentally ordered too many, so I'm selling them. I wore them for about 12 hours at Universal Studios Japan, including 4 hours of walking, and my feet felt very comfortable! I had to select a size because I chose "shoes" as the category, but I think they can basically be used in any shoe.
