I've been loyal to a more popular sock brand for a few years now, but I was curious to try out Wrightsock's signature "double layer" design....I'll never go back to anything else! These are seriously the most comfortable socks I own. While hiking, I've stayed blister-free, as the socks don't get too sweaty throughout the day. At night, I wear them to sleep and they keep me toasty warm. Seriously, I can't say enough good things about these socks. Absolute new favorite accessory!!!!
