The superbly named Darn Tough Socks has the feet of just about everyone covered. The family-run firm tailors their merino foot snugglers to suit everyone from office workers to hikers to runners. Billed as the world's best sock, they sport the likes of high density knitting, a cushioned sole and ribbed support to eliminate bunching and blisters, while the fine gauge, itch-free wool construction regulates temperature, wicks moisture and repels odor.
