Pound the ground and put in the miles. It’s never easy, but at least it’s comfortable with the ultra-lightweight Stride running sock. Extra durability was knit into the heel, footbed and at the first and fifth metatarsal (outside toes). This micro crew sock features smooth, anti-chafe Merino Wool, with cooling mesh and a low-profile, next-to-skin fit that will match any hundo you throw its way.
