What Our Gearhead(R) Experts Are Saying:"I wore the Spaced Out Sock on a long desert day hike where heat and dust were relentless, and my feet stayed fresher than expected from a lightweight sock. The terry cushioning over the ankle and Achilles made a noticeable difference on rocky terrain, and there was zero bunching from trailhead to finish."Hot miles, dusty switchbacks, and a summit that keeps looking farther away than it should. The Darn Tough Spaced Out Micro Crew Lightweight Cushion Sock was built for exactly that kind of day, delivering the kind of underfoot comfort and moisture management that keeps you moving when the trail gets long and the temperature climbs. Knit from a merino-forward blend at Darn Tough's Vermont mills, the Spaced Out naturally regulates temperature and resists odor through multi-day efforts and back-to-back adventures. Terry loop cushioning targets the underfoot, ankle, and Achilles for protection where trail runners and hiking shoes apply the most pressure, while the True Seamless(TM) toe closure removes any friction that could turn into a problem over miles. A performance fit locks the sock in place without bunching or slipping, and the unconditional lifetime guarantee means these are the last lightweight hiking socks you will ever have to think about buying.
