    • Warm, Comfortable and Well Made -- Perfect for Dog Walking in the Winter
These are warm and comfortable. They were gifts for a brother, husband, and son. All have dogs they walk in the winter. The shoes were true to size. The reviews from them have been very positive, with comfort being at the top of the list. They are a little more expensive than comparable brands. But, worth it for all three of them. ... show more

    • So warm and comfortable and durable
Size: 10 Color: Phantom Grey Heather Print/Tnf Black
My husband and I are both obsessed with these shoes. Just bought his second pair after five years of wearing his first pair 70% of the year (amazing quality considering one of the souls just gave out). These are very warm for your feet and great to wear outdoors. They are like a pillowy hug. They are waterproof (my baby even spit up all over my husbands yesterday and we just wiped it right off lol). Fits true to size but with room. They fit perfectly before pregnancy as well as after when my feet grew a shoe size. ... show more

    • 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

    • Best house shoes
Size: 11 Color: Tnf Blue/Tnf White
I bought these North Face Thermoball Traction Mule shoes for my partner for Christmas, and they turned out to be an amazing choice. They arrived in his correct size and provided great support and comfort right away. The color looks even better in person, and the material has a nice thick feel that adds real warmth during colder months. The quality is impressive, and for what they offer, I would say they are a great value for the money. One thing we appreciate most is how functional they are, since he can wear them both inside and outside with plenty of protection and traction. They feel sturdy, warm, and very durable, almost like a blend of a cozy slipper and a dependable outdoor shoe. We loved them so much that we have already purchased two additional pairs. These are stylish, comfortable, and reliable house shoes that truly stand out. Love the functionality of them . ... 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.

    • 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

    • FINALLY!! Comfortable slippers that...
Size: 10 Color: Thyme Brushwood Camo Print/Thyme
#9 I now have every color except the ugly ones - and they are SO SWEET. I wear them year round - summer, not too warm or anything. Winter - i literally walk my dogs every morning in the snow and it's freaking freezing out here right now... 4am and my feet stay warm and dry... 59 DOLLA Say WORD!! 🤙🏽🤙🏽 .That also: keep my feet warm, are comfortable with or without socks, a plus for the winter months ✓ and they also fit sooo great!! I've been trying for 3 months to get the right pair of indoor/outdoor occasionally -- maybe be a good thing for snowboarding - (i mean to pack and bring to the mountain) not actually ride in although I think they're warm enough, and have enough grip- but I'm afraid the toe & ankle support just might be a little bit sketchy lol. So anyway, yeah to be able to wear in the lodge for an "apres-- ride?" -- well, regardless of how it's said in French - after I get off the hill from a day of hard riding, my feet are screaming at me to get out of my boots, AND SOCKS! Put on a fresh pair of socks, and then---? That's always been the question! I mean if you want to go up to the lodge restaurant or pub, and have a few, these are perfect. If you just want to eat- PERFECT. Tired? I understand bro! These will be warm from the moment you step outside of the lodge, through your 10 mile walk to get to your car - LOL - and in the car the whole way home. And seriously -- THESE are better on ice than hockey skates! I've tested them, and I can't even believe it. For real? YEAH I'm being totally 100% str8up serious with you. And the camo looks badª§§. Love it. Wish I had more occasions to rock out with these on - I'll find some, trust that. Aiiight y'all, you already know -- But ok -- for the record: I ABSOLUTELY LOVE THESE AND 4SHO 110% RECOMMEND THEM! (ALTHOUGH BLACK LOOKS LIKE A PENGUIN AND ALSO LIKE MISSY MISDEMEANOR ELLIOTT IN THE 90S IN THAT EFFED UP WEIRD A*XE VIDEO I CAN'T STAND THE RAIN OR what ever it's called... not a great look, but Red, Camo (the one I got whatever they called it) and the other camo+ also a strange name, but it has "Camo" in it so I'm comfortable you will be able to navigate to it on your own.

I liked my original tall pair so much I bought these for lounging in the house. The heel cups fold under the foot quite comfortably, even while walking, which surprised me. Light, soft, warm, comfy, breathable, and non slip. No more sweaty stink foot, darlin. Arguably better than all the more expensive slippers and moccasins I've used before. ... show more
