The Stance Divide UL Wool Snow Sock uses a merino wool blend to hold warmth through a full day on the mountain without packing extra bulk into a ski or snowboard boot. Thermoregulating fibers and ultralight cushioning keep feet dry and comfortable from first chair to last run, while graduated compression through the leg supports circulation on long days standing in a boot. Reinforced heel and toe zones and a deep heel pocket keep the fit locked in over the calf. What Our Gearhead(R) Experts Are Saying:"My boots still buckled the same after I swapped in these socks, the wool stayed warm through a full day without adding the bulk that usually throws off my fit."
