Designed for those that tackle the trails and want the extra cushioning and protection from the terrain, Injinji Performance Trail Midweight Crew Toesocks feature cushioned pads under the heel and forefoot for protection and shock absorption, with Injini's anatomical 5-toe design helping prevent blisters and freeing your toes to grip.  A double elastic cuff helps to keep dirt from the trail out and hold the sock in place, keeping you comfortable throughout your run.
