The Smartwool Hike Light Cushion Ankle Sock is built to match low-cut hiking shoes without sliding down into them the way a lot of ankle socks do. A comfort welt keeps the top of the sock locked in place, so the fit holds through climbs, descents, and everything in between. It's part of an updated formula with increased durability and a women-specific fit, built with ZQ-certified merino wool and recycled nylon for genuine sustainability credentials. What Our Gearhead(R) Experts Are Saying:"I climbed a full day in low-cut trail shoes and never once had to reach down and pull these back up."
