What Our Gearhead(R) Experts Are Saying:"I wore these on a multi-day summit push where my boots stayed on for hours at a time without a break. The mid-volume cushioning protected my heels through every mile of approach, and my feet never got cold even above the snow line."A high summit push means hours on your feet before the real climbing even starts, boots laced tight and every ounce of gear already accounted for. The Elite Mid Volume Sock from Hot Chillys carries its weight on days like that, mid volume cushioning built into the leg and foot to protect against the pounding of a long approach without adding bulk your boots can't spare. Far infrared yarns work with the body's own energy to hold warmth through exposed ridgelines, while carbonized coffee fibers keep moisture and odor in check across days without a shower. Arch compression supports the fit through mile after mile, and over the calf length keeps cold air from working its way in above the boot. Built for the climb, and just as ready for the descent after.
