Thermoball Lace 8in Boot - Women's

If the dictionary had a picture next to the word, "toasty," it would be a photo of  The North Face Women's Thermoball Lace 8in Boot. PrimaLoft's latest innovation, ThermoBall synthetic insulation mimics down's lofty warmth, except it stays warm when wet, which might not even be necessary considering the recycled upper sheds snowfall to keep it dry. The upper also features a synthetic mudguard that fends off slush and snow as well as mud. OrthoLite's ReBound footbed is surprisingly cushy for how thin it is, and there's an injection-molded EVA midsole for stability. The North Face's Winter Grip sole features temperature-sensitive IcePick lugs that stay grippy in frigid temperatures.
