The Smartwool Ski Zero Cushion Nightwatcher Print OTC Sock - Women's strips away cushion for a precise, direct feel inside a tight-fitting boot, then reinforces the one spot that wears out first on a thin sock. Shred Shield(TM) technology works with a Virtually Seamless(TM) toe to cut down on wear right where a boot presses hardest, while Indestructawool(TM) reinforces the rest of the high-impact zones. A narrower, women-specific heel and the 4 Degree(TM) Elite Fit System keep everything anchored, and merino wool handles temperature and moisture the way it naturally does. What Our Gearhead(R) Experts Are Saying:"I've put a full season of days on these, and the toe still looks like it did in November instead of thinning out the way a zero-cushion sock usually does by spring. Shred Shield is clearly doing more than a marketing name."
