What Our Gearhead(R) Experts Are Saying:"I wore these through a full day of back-to-back laps with barely a break to sit down. My feet stayed warm the entire time, and the mid-volume cushioning kept my boots comfortable even after hour six."A day built around as many laps as daylight allows doesn't leave much room for cold feet or boots that stop fitting right by hour three. The Elite Mid Volume Sock from Hot Chillys holds its shape through all of it, mid volume cushioning placed exactly where boots need it most, so comfort doesn't fade as the hours stack up. Far infrared yarns draw warmth from the body's own energy while carbonized coffee fibers keep moisture and odor under control from first run to last. Arch compression keeps the fit locked in through hard, repeated effort, giving feet one less thing to think about on a day meant for nothing but skiing.
