Worn once. Overseas size 37, but it feels like it would fit someone who wears a 22cm to 23cm shoe. It might even fit a 22cm foot if you wear thick outdoor wool socks. (My 23.5cm foot touches the toe.) I loved these for camping, but they're too small for me, so I'm offering them to someone who can wear them. Shipping will be done by wrapping the box as is.
