Red Chili AMP climbing shoes, a high-performance model with Vibram soles. "Purchased new and used for only six months. Worn with socks. In relatively good condition. Size: UK4 US5 EU37 I believe this corresponds to a Japanese size of 23.0cm." I have a 23.5cm foot, but I bought these hoping for an aggressive fit. As a result, they were too tight to wear comfortably, so I'm reselling them. These are really for someone with a #23.0cm or #22.5cm foot. Thank you! (=^ェ^=)
