Thank you for looking. These are Montbell Sawa Tabi (river tabi socks) in size 24cm. I used them once in a river, and they provided excellent sole sensitivity, allowing me to easily ascend the river. Unfortunately, they didn't fit me well, so I am selling them. [Product Information] These tabi socks offer a very soft feel and excellent sensitivity for your toes and soles. The upper is made of 3mm thick Climaprene® for warmth. The outsole uses Aqua Gripper, which provides grip even on wet rocks. They can be used on their own or combined with "Sawa Sandals Felt Tabi" for various situations. [Materials] Upper: Climaprene® [3mm thick chloroprene rubber (both sides jersey)] Sole: Aqua Gripper [Weight] 320g (26.0cm, one foot) [Color] Blue (ORBL)
