Engineered for snowy & icy trails, the Pedroc Mountain Spike Crampon is made of hardened 9-12 mm stainless steel spikes connected by lightweight steel cables and strong chains to withstand repeated torque. The durable elastomer harness has a Velcro strap that allows you to tension the cables for a precise, wrapping fit at the forefoot and midfoot. The spikes are easy to pull on and take off thanks to their fabric heel loop. In addition, the design fits a range of different shoe types. Supplied with a compact storage bag.
