For a long, cold day on the mountain, we pull on the Smartwool Ski Targeted Cushion OTC Sock to ensure our feet stay warm and comfortable in our boots. Its Merino wool blended construction is exceptionally warm, while body-mapped mesh zones ensure our feet and calves can breathe. A Women's specific fit, featuring a narrow heel and slim fit, combines with a Virtually Seamless toe and wider welt for a more secure and comfortable fit.
