Sub freezing temps, whiteout conditions, and snow covered sidewalks can't stop the tenacious grip and fiery warm insulation of The North Face Women's Thermoball Bootie. This cold weather favorite features a sleek, feminine silhouette, giving you fashion forward style for winter's worst weather. Its toasty ThermoBall insulation traps heat within its down like clusters for ample warmth through frigid conditions. Plus, its recycled P. E. T ripstop upper and protective synthetic mudguard shed moisture from trekking through snow and slush covered walkways. Adding plush comfort, there's a supremely soft Oso fleece covered OrthoLite footbed. Keeping you from slipping on icy streets, the bootie's IcePick rubber sole has temperature sensitive lugs that claws into frozen surfaces for sure footed grip.
