Black Diamond Access Spike Traction Device

The Black Diamond Access Spike Traction Device is a trail traction system designed for winter training runs, mountain approach hikes, and early-season scrambles where the trail surface shifts between packed snow, ice, and rock without warning. Fourteen stainless steel spikes per side, each 8mm long and heat-treated for wear and corrosion resistance, engage all three surface types effectively. A full elastomer harness with reinforced dual-density eyelets fits over a wide range of footwear, and a front-point spike positioned at the toe optimizes grip during active push-off. A heel webbing loop simplifies donning and heel-side identification on the trail. Pair weight ranges from 3.7 to 4.23 ounces depending on size.
