    • Warmth and Comfort Redefine: North Face ThermoBall are a winter MUST HAVE!!!
Size: 11 Color: Summit Navy/Tnf White
I bought these for a winter trip to Tennessee, the Smokey's. Boy!!! did I need them. Let's get right to it: 1. These provided excellent comfort and warmth and thus far they have been durable. I've had them for 4-5 months and NO SIGNS OF WEAR AT ALL. 2. Even in 16deg weather, these stood up to Mr Jack Frost. Very warm! The insulated cushion foot-bed makes it feel like you are walking on clouds. 3. The slip on design is excellent for me. I like to be able to just kick my slippers off when needed. This is THAT. And, the back of the heel is a sort of elastic stretch material. So, it doesn't "scrub" your Achilles area. If you are the type to "walk on the back" of your house slippers, don't worry. The elastic just bounces right back each and every time. 4. These are versatile, not that I do this but, you can walk outside with these. They have actual outdoor tracking on the bottom. You aren't even going to slip in a small amount of water in these. 5. They look good - yes, that matters to me and many people. I didn't want those "older" looking house shoes that you pick-up from Walmart. Don't get me wrong, I have purchased many pair from there but I wanted something sleeker and more fashionable this time. 6. Cost - might be on the slight upper end for some people. But the fact that they are exactly what I needed makes them worth it to me. The things I would caution about: 1. They do fit somewhat snug. I would buy a half-size larger to be on the safe side. 2. For some, they may be too warm for southern climates (however, depending on the person, you may need a warmer slipper in a southern climate). ... show more

    • Great weather-proof slippers.
Size: 12 Color: Phantom Grey Heather Print/Tnf Black
They're very comfortable, and most importantly, weather-proof. I really like the design as well. They seem to run slightly small for me, so I'd probably go for a 12.5 instead of my usual 12, but they do slip on as easily as I'd expect them to without feeling too loose.

    • Great Indoor outdoor Houseshoe
Size: 12 Color: Tnf Black/Tnf White
I have only had these she for a couple weeks so I really can’t speak about hiw durable they are, but I can speak of the construction base first impression. The shoe appears to with a solid sole and rubber rim around the sole that provide a sturdy construction. The shoe material is the same as a shell coat and seems to be well put together. A few complains that I have noticed in reviews is that the band around the ankle is too tight and whether the shoe is too insulated for warmer climates or not enough for cold climates. As stated by many reviews, I purchased a size up. I normally would purchase size 11 but purchased a size 12. The fit was perfect and the ankle band was also. The shoe I have been wearing it around the house a lot in warm or cold weather and it seems to provide comfort in both cases. The temperature recently went down in the mid-twenties and fir activities like taking the garbage out or quick runs to a store they jeep my feet warm. The shoes are advertised as a camping shoes for walking around the camp at night. I think that they would meet those needs well. But if someone was going to use them as winter shoes for cold weather, then I doubt that they would suffice. I am glad I bought these shoes and considering purchasing another pair since I like them so much. Update: I have had these shoes for two months and have wore them almost ever day. I have wore them to get groceries, work in the back yard rebuilding a gate, in wet weather, digging up roots and other times. I have got them sirty, muddy and wet. I have thrown them in the washing machine three times so far and each time they have came out looking brand new. ... show more

    • Great for winter house shoes.
Size: 12 Color: Phantom Grey Heather Print/Tnf Black
I wore these through most of one winter as house & patio shoes, and I am satisfied. I agree with others that a full size up is appropriate. I am usually 11 or maybe 11-1/2, and the size 12 is still almost too snug. They are quite comfortable and decent cushion for our laminate floors. I would love if I could find slippers that have similar cushion to my Brooks Glycerin running shoes, but alas, I am not convinced that exists. The only noticeable wear so far is the north face lettering on the inside heel is wearing off. ... show more

    • Good shoes
Comfy and durable but water (rain and snow) get through pretty easily. Too warm in the summer but great the rest of the year. Adequate traction for walking the dog on pavement and grass.

    • These are fantastic!!
Size: 9 Color: Summit Navy/Tnf White
I love these shoes! I wear them around the house and have found they are great to wear watching sports in a cold stadium. I constantly have cold feet, but my feet will actually sweat in these because they keep your feet so warm. These are better than wool socks for me. Two things to take note of: 1. I almost sent them back originally because there is a tiny label sewn into the inside heel of each shoe. It kept rubbing my foot and felt like a small piece of plastic. Took me awhile to figure out what it was. I trimmed the label corners and that fixed the problem for me so I ended up not returning. 2. These have a low rise sole/heel so they feel like "barefoot" shoes if you start to walk any distance in them (like walking around a large parking lot and football stadium). That is fine with me because I use barefoot style shoes all the time, but I did notice it so be aware. ... show more

    • Works almost too good
Size: 12 Color: Summit Gold/Tnf Black
Love these, super comfortable, lightweight and have great traction. I have to wear them with socks otherwise my feet get too sweaty. They do tend to run small so size up if you decide to buy. Love the color options as well, the last thing the world needs is another pair of brown slippers.
