Don't let winter hinder your running routine, the Atlas Run Snowshoes are light and agile, letting you keep your pace high through the snowy months. Tough, sleek frames are crafted from 6061 aluminum to create a stiff, lightweight chassis and are shaped to maintain flotation while reducing contact area. Spring-Loaded? Suspension (SLS) uses offset webbing straps to create a springy platform beneath the foot that absorbs impact and allows natural side-to-side foot flex. 1-pull webbing strap bindings cinch tight with a quick tug, supplying a snug, supportive fit that's lightweight and flexible; heel straps secure feet further. Lightweight Nytex? nylon decks are abrasion-resistant and stay flexible when cold and stand up to the elements for lasting use. Aluminum instep crampons bite into snowy terrain with a front row of teeth and 2 side teeth to minimize twisting; aluminum heel crampons maximize downhill traction. Recommended load specification includes weight of runner with gear; the Atlas Run snowshoes can support up to 220 lbs. on packed trails.
