Not everyone is disappointed by socks on Christmas. For homeless people living on the streets, a fresh pair of socks can mean all the difference between healthy feet and infections, blisters, or frostbite. Charles Mark & Sons, for one, wants the oft-maligned coverup to be the gift that keeps on giving. Fresh off a successful crowd-funding campaign, the Texas startup aims to create high-quality, stylish men’s socks that benefit those in need. Cribbing a page from TOMS’ playbook, for every pair of socks you buy, Charles Mark & Sons will donate another to The Joy of Sox, a charity that distributes clean socks to homeless shelters across the country.
