These flat-soled shoes are for beginners to intermediate climbers. They were used by a child wearing socks. While there is some wear on the soles, they still have plenty of life left, so they will definitely be easier to climb in than rental shoes. EUR size is 35.5. They should fit someone who usually wears 21-22cm shoes (with socks). If worn without socks, they might fit someone who usually wears 23cm shoes. They were deodorized with newspaper after each use, so there shouldn't be any noticeable odor. No box or tags. They do not have heel hooks, etc.
