What Our Gearhead(R) Experts Are Saying:"I wore the Steep Lines OTC Sock on back-to-back big days in the alpine and my feet stayed dry and fresh through all of it. The lightweight cushioning at the sole and ankle gives just enough protection without adding bulk inside a performance boot, and the over-the-calf cut never once slipped down."The runs that earn their names are not the ones you take easy. They demand focus, commitment, and gear that holds up through every aggressive turn and consequential descent. The Darn Tough Steep Lines OTC Lightweight Cushion Sock was built for exactly that level of skiing, delivering technical performance from the ground up so nothing between your foot and your boot becomes a distraction. Knit from a merino wool blend at Darn Tough's Vermont mills, the Steep Lines naturally wicks moisture and resists odor through long days and multi-day efforts in the mountains. Lightweight cushioning at the sole and ankle provides responsive protection without the bulk that compromises feel in a performance ski boot, while a reinforced Achilles absorbs impact and eliminates heel lift during hard charging descents. The True Seamless(TM) toe closure removes friction entirely, the over-the-calf cut seals out cold and stays put all day, and the unconditional lifetime guarantee means these socks are built to outlast every season you put them through.
