I purchased these a few years ago and wore them about 3-4 times before storing them. This is just a guide as it varies from person to person, but I usually wear shoes that are 26cm-26.5cm, and there's about one finger's width of space in the toe area. I don't plan on wearing these anymore, so I'm selling them to someone who will. Shipping will be via Takkyubin (Yamato Transport) in an 80-100 size box, so the price reflects the shipping cost.
