What Our Gearhead(R) Experts Are Saying:"I wore these on a three day hut trip where my legs usually give out by the last descent, and they held up better than expected. The compression seemed to actually help on the hike back up between runs."Multi-day trips wear legs down long before the snow does, and the Boyd UL Poly Snow Sock is built to slow that process down. Stance kept the cushion ultralight so the sock never adds bulk inside a boot, while graduated sport compression works underneath to support circulation through long stretches of standing, hiking, and riding. Infiknit reinforcement toughens up the heel and toe against the friction of a stiff boot shell, holding up trip after trip without breaking down. A seamless toe closure and deep heel pocket keep the fit locked in and irritation free, and performance mesh keeps feet breathing even when the effort ramps up on a long skin track or hike to the next line.
