Think of all the possibilities: ice fishing, trail walking, spring backpacking, icy approaches and more. Our Instep Crampons are a lightweight and secure solution to the slippery problem posed by icy ground and packed snow. These attach securely and quickly with nylon straps that slip over the heel then snug down over your instep. Adjustable width and a built-in hex-wrench. Weight: 296gm (10.5 oz)/pair.
