"Good Compression and warm"
"Might be my favorite ski socks so far. Love the compression and great fit."
"These socks really should not be advertised as ski socks. Although the majority of people buying them might appreciate them because of the cushioning and thickness, that might keep their feet warm, they are too thick for a serious skier who is looking for a technical sock that will work with the tight fit of their boots which provides better control and comfort because the foot isn’t moving around in the boot."
"love the secure fit and perfect warmth"
"Good compression, warm and comfortable. The foot sizing was great but the sock itself is a little long (could stretch above my knee if I kept pulling up). Still very happy"
