What Our Gearhead(R) Experts Are Saying:"I take these out when I know conditions are going to be rough-icy ridgelines, hard-packed trails, or sketchy approaches. The front-point grip gives real bite, and the elastomer holds tight even when layered over burly insulated boots."When the trail turns icy and hard-packed snow becomes a daily reality, we count on the Snowline Ultra Spikes for next-level traction. With aggressive front points and a full crampon-inspired frame, the Ultra takes winter mobility seriously. Whether we're out for a frosty hike, working in remote terrain, or crossing steep, frozen hillsides, these spikes give us confidence with every step. Built for maximum durability, the Ultra Spikes feature hardened steel underfoot and a heavy-duty elastomer harness that flexes easily over lightweight or insulated boots. Reinforced chain links and a stable heel plate add extra security in uneven terrain, and the five-size range ensures a precise fit. When our winter work or wilderness play demands surefootedness, the Ultra delivers.
