I bought these new for river crossings during my climb of Mt. Poroshiri and only used them once. If you wish, I can also include the socks I bought with them. These have also only been used once. Please comment if you want them when you purchase. ————— Product Information The outsole uses polypropylene felt, which is resistant to moss and slime. The shoelaces are a model with a cord lock specification that makes them easy to tighten. The lace cover integrated with the ankle gaiter reduces snagging and damage to excess cords.
