When the temperatures are sub zero, you need a boot that's built to tackle those extremes. Enter the Women's Chilkat III Boot from The North Face for all your cold weather footwear needs this winter. The North Face used waterproof suede and PU coated leather for the uppers, as well as thermo plastic rubber for even more waterproof protection. Because being dry won't help if you're still cold, The North Face added 200 gram Heatseeker synthetic insulation as well as a fleece collar for warmth. Whether you're on your feet all day or just for an hour or so, you'll appreciate the support and stability of the compression molded EVA midsoles. To help keep you upright and not slipping around everywhere, Winter Grip rubber outsoles were used along with IcePick temperature sensitive lugs for the best traction in all possible conditions.
