I purchased this at an Alpen store last year. It's unused. 26.0 cm How about these for a junior high school student's commute? They're lightweight and made of breathable mesh material. They seem suitable for the coming season. I think it was like this from the beginning, but the right shoe looks a little yellowed. Please check the photos. (7th and 8th photos) These have been stored at home. Please purchase with the understanding that they are stored at home.
