North Face Women's ThermoBall Traction Bootie size 8, brand new with tags and box. The slip-on Women's ThermoBall Traction Bootie pairs warm and comfortable insulation with a high-traction rubber outsole, making it ideal for base camp, après ski or shuffling through the snow to grab the morning paper. WATER-RESISTANT DURABILITY. Made with a recycled ripstop upper and coated with a Durable Water Repellent (DWR) finish, these highly durable winter shoes are water-resistant and warm. RECYCLED INSULATION. Take on the cold with superior warmth and recycled materials. Thermoball Eco uses small, round synthetic fiber clusters that closely mimic the way down insulates: trapping heat within small air pockets for warmth retention. SUPERIOR TRACTION. Move around confidently and with a clear conscience thanks to a partly recycled rubber outsole with supreme traction. From base camp to peak, you'll love the ability to stay grounded and maintain traction.
