The Darn Tough Men’s Hiker Boot Midweight Hiking Sock (Style 1403) in Lime is a men’s boot-height hiking sock with a midweight cushion layer underfoot — denser than lightweight trail socks, thinner than heavyweight winter socks — for day hikes, long approach miles, and multi-day trips inside mid and full hiking boots. The boot-height shaft rises above the boot collar, keeping the cuff clear and preventing debris from dropping into the boot. True Seamless toe construction closes the front of the sock smoothly so there’s no seam rubbing across long trail days.
The knit — 64% Merino Wool, 33% Nylon, 3% Lycra Spandex — runs heavily merino-weighted so the sock handles moisture wicking and temperature regulation through cold morning starts and hot afternoon climbs. The nylon percentage keeps the sock durable against trail-mile wear, and the spandex keeps the cuff tight around the calf. Lime is the bright trail-ready colorway that adds a high-visibility pop to outdoor kits.
Darn Tough knits every pair in Northfield, Vermont and replaces any pair that wears, tears, or develops holes under its lifetime guarantee.
