What Our Gearhead® Experts Are Saying:"I switched to Injinji toe socks after struggling with blisters between my toes on long trail runs, and the difference was immediate. The merino wool upgrade takes an already great design and adds natural odor resistance and temperature regulation that makes these my go-to for anything longer than a few miles on rugged terrain."Blisters between the toes are one of those trail problems that feels unavoidable. At least until you try a sock designed to prevent them. Injinji's Outdoor Midweight Wool Crew Sock wraps each toe individually, eliminating the skin-on-skin friction that causes hotspots during long miles on rugged terrain. The five-toe design also promotes natural toe splay inside the shoe, letting the foot function the way it's meant to. The merino wool upgrade brings the rest of the package together. A 75% merino blend manages moisture, resists odor through multi-day efforts, and regulates temperature across variable trail conditions, while a midweight terry footbed adds cushion where the trail demands it. For hikers and trail runners who've been putting up with blister problems, this sock is the straightforward fix.
