Men's Bolt Micro Crew Ultra-Lightweight Cushion Running Socks

Scorching the streets or grinding out new backcountry PRs, it's hard to argue with the inspiration of the Darn Tough Bolt Micro Crew Ultra-Lightweight Running Sock Men's vintage van stripes. Pop the hood and you'll feel the benefit of ultra-lightweight Merino Wool, and a redesigned, smooth-and-supple upper, paired with arch support below. You could say the cushion underfoot is kind of like shocks, or they will shock- either way is accurate. Being powerfully fast and strikingly stylish is not a myth.
