Darn Tough Vermont Women's Light Hiker Micro Crew Light Cushion Socks have increased breathability with mesh panels on the top of the foot and a smooth ribbing upper that always stays put. These socks won't slip, bunch, or cause blisters because of their performance fit. Fine gauge knitting offers unprecedented durability and a unique "put it on, forget it's on" feel. The fast action wicking not only pulls moisture away from you skin quickly, but also dries fast and the merino wool, that's naturally antimicrobial, repels odor causing bacteria. For an invisible feel they use True Seamless technology that is an undetectable seam fusion. The Darn Tough Women's Light Hiker Micro Crew Socks are ready for any condition imaginable.
