Customer Reviews The North Face ThermoBall™ Traction Mule IV

Just to walk around in winter

They are very comfortable and keep your feet nice and warm. Just wish they were a little easier to slip on. They do run a little tight. I would only recommend to wear in the winter. Once spring time hits, you don't really need them. In fact, your feet start to sweat.

I wear them at home or when I need to go do a quick run to the store. They are very Comfortable And Stylist.

Warm, stylish, and durable. I got these for use around the house and around the campsite.

A good Christmas gift!

i use this shoes for resting in my house and are very good, warm and confortable.

the shoes is perfect to be around your house, going shopping and going place where you don't need to be dressed casual.

Great pair of easy slip on shoes.

True to size and is warm and functional. They're a little wide and (although light) appear bulkier than I expected.

I wear this product as House shoes also when I go places.

The Thermo-ball Mules were a step up from the previous slippers from 2015. The outer slipper and bottom of slipper wear very nicely the heal and innersole should be improved. If that happens, these will be the best, warmest slippers on earth. My suggestion would be to sell these with a heavy winter insole and a light breathable summer insole. That might drive the price a bit, but for those looking to have a year round slipper I think they would gladly pay for them. I also wish that TNF would sell the correct insole to replace the old ones. After calling, I found out that TNF will refer you to the manufacturer. Combined with the rear section that does wear out is the reason the slipper did not get 5 stars.

First pair sent back, inside seam had hard piece inside which dug into my foot. Shoes would fit better if there was more insulation and were not so wide

At home and on the quick ride

I got these shoes as a Christmas gift and have been wearing them off and on around the house as slippers. They are very comfortable and warm however, after only ten days out of the box, the fleece lining in one of them has already started to rip. Just another example of TNF mass produced poor product quality. Now I have to deal with warranty issues. Either sending them in or trying to get this rectified at a TNF store.

I bought this shoes for wearing them after climbing in the tent or around the hose. Although they are well made and comfortable the sizing is off, they run way big and the recommendations on the web site for the correct fit was wrong

I bought my first pair a few years ago. While I liked the slippers when I purchased them it became very clear that the insole was less than satisfactory. I was able to contact TNF customer service and they gladly produced the insole makers name. Upon finding out the price was more than half of the slipper (retail) I decided to purchase another pair of the slippers from TNF as they had become the Thermo-ball tech. I had exactly the same problem with the insole and I am currently looking for another brand that won't wear our in only a few months. Please note that the outer shell is fine but my feet tend to contact the insole more that the shell. I own a ton of TNF clothing so while not every product is up to snuff, I still recommend TNF to everyone. My Ultra-FastPack boots are great!

Bought these for my son for Christmas. The sole came out the next day. Not happy with the quality.
