Why We Like the ThermoBall Traction Mule V Wool Bootie

After a long day of carving lines in the backcountry, we look forward to slipping into The North Face's ThermoBall Traction Mule V Wool Bootie and sitting by the fire with bevvy in hand. Toasty insulation warms our toes while the sticky sole keeps our weary legs under us as we venture along the icy walkway to grab more firewood from the shed.

Super Slow Shipping

I had to have my shipment rerouted because I was leaving the original address where I had it shipped. UPS expected delivery looked on time then they changed delivery to the next week. Looked like backcountry didn't even get it out the door for three days from the oder date. Super annoying.

Bought these for a casual bootie for my days working at home. They are extremely comfy and the foot bed is very soft as well. The merino wool helps keep your foot warm and happy. One thing to know is that the bootie looks a little wide when wearing them, These might not be the best option for skinny feet. However, they fit great for medium-wide feet. The nice thing about the rubber sole is that it can be worn outside even in some light snow. I love to take these when I go skiing as changing from ski boots to these at the end of the day is incredible.
