"Looking for a sock that’s so perfectly fitted to your foot that you’ll forget you’re even wearing it on the trail? Swiftwick has you covered. Their all-new FLite XT Trail sock is designed with the rugged, warm weather phenom in mind; hikers who don’t balk at a steep set of rock stairs or trail runners who go hard in adverse conditions. With bespoke AnkleLock technology to protect against heel rubbing and grippy fabric in the heel and forefoot to prevent in-shoe sliding, this is a truly excellent sock for your wildest adventures."
