NWOT. Smoke free, pet free home True to size: This footwear is true to size for a supportive, comfortable fit. Take on the snow in these cosy mules 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™ 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.
