These are snow spikes to be attached to the center of Montbell shoes. ※The actual product is the blue one from the 4th image onwards. These snow spikes have 8 claws with grip in both vertical and horizontal directions, and the "wave-shaped anti-snow plate" with a wavy bottom surface of the plate suppresses snow adhesion, maintaining the original grip of the spikes. In addition, the plate itself supports grip, and the rib structure minimizes deformation, preventing snow from entering between the shoes and the spikes. The material of the spike body is S55C carbon steel, which is extremely hard and has excellent abrasion resistance. The spikes are a simple model that attaches to boots with rubber bands. They are lightweight and compact, making them convenient to carry. I have used them once, so there is some paint peeling on the tips of the claws, small scratches from use, and some slight dirt on the stuff sack, but there are no noticeable large scratches or stains. The size is free size, and the compatible shoe sizes are 21.5-30.0cm. Comes with a stuff sack. Set of one pair (left and right). #MountaineeringGear #WinterMountains #SnowShoes #Crampons #Trekking #Trail
