Take on the snow in these cosy The North Face Mens ThermoBall V Traction Winter Mule Black White to grab the morning paper, or relax after a long day on the mountain by the fireside. Sub-zero conditions are no match for our ThermoBall Eco insulation and cosy fleece lining, which keep your feet warm and snug when you're relaxing. When it's time to shuffle through the snow to bed, you'll find the tough ripstop material and high traction rubber outsoles are just right for the job.
