Why call ’em Drynamite Socks? Because you’ll be blown away by dry, chafe-free comfort unlike anything your feet have ever experienced. The unique combo of fast-wicking Dri-Release polyester and BlisterGuard yarns blasts moisture away from feet and reduces friction – heading off painful hot spots and blisters before they begin! Extra-stretchy support at the arch keeps the spring in your step when you’re on your feet from dawn to dark.
