I bought these this year and wore them a few times, but I realized I had the wrong size, so I replaced them. (They were so good that I bought the same ones, just in a larger size.) Since I was the one who made the mistake with the size, I think the size will be the same as your usual size. ≪Material≫ EVA To reduce shipping costs, I will pack them slightly compressed. Please purchase only if you understand this. Color: White系 (White-based) Strap: With strap Season: Summer
