The Blitz Spike is Black Diamond's ultralight trail traction device at only 45 grams per device. Engineered for fast and light missions with ultimate packability, the Blitz Spike features 6 stainless steel spikes on the forefoot for superior strength and durability. Drawing from their extensive experience designing climbing crampons, the 6 forefoot spikes have an optimized 8mm length, designed to provide excellent engagement on snow and ice, with improved stability on rock when the trail ends and the scramble begins. The heel retention elastomer and webbing toe loop keeps the Blitz featherweight while providing a stable and secure fit.
