These are shoes for river trekking. They provide an excellent fit, similar to waraji sandals, by pulling the laces from the heel side as well. The toe area is split like tabi socks, preventing foot slippage. The outsole uses polypropylene felt. Note: Tabi-style socks are required. Specifications: 【Material】(Upper) Clima-prene® [4mm thick chloroprene rubber <double-sided jersey>] (Sole) Polypropylene felt 【Color】Blue 【Size】27.0cm Although used infrequently, there is some discoloration due to aging.
