The Smartwool Ski Full Cushion Ice Blossom OTC Sock packs in maximum cushion for the days that run from first chair to last call, backed by Indestructawool(TM) durability knit into the zones that wear out first. A Virtually Seamless(TM) toe removes the seam that usually causes friction, cutting down on blisters over a long day in the boot. The 4 Degree(TM) Elite Fit System locks the sock in place with strategic stretch and mesh zones, and a narrower, women-specific heel keeps everything secure without slipping. What Our Gearhead(R) Experts Are Saying:"I've skied a full day in these, first chair to the last lift, and my feet never went cold or raw at the toe seam the way they have in thinner socks. That extra cushion is what gets me through the whole day, not just the morning runs."
