These run small, for my foot anyway. I wear an 8-8.5 and ordered a 9. My toe hits right up against the edge of the shoe. I am assuming they will stretch out a bit. Other than that, they are extremely warm and comfortable. It feels like memory foam on the inside bottom. They are a bit too wide at the heel but that is okay. They are very warm and the most comfortable slipper I have every worn. I would give it a 4.5 if I could, but only whole numbers are optioned, so I gave it a 5. I suggest ordering up a size.

They are so comfortable and warm. The leather is really soft and they are exceptionally well made. I wear them with skinny jeans tucked into them.  I think they look great, casual but classy. I ordered a half size too small originally but the customer service was great and they straight away sent out a size bigger and they fitted perfectly.

These feel so luxurious!  It'll take a day or two to know if they're as comfortable as my last pair, but right now I'm loving them! They're so soft and warm.  I also like that they've gown rid of most of the holes in the winter crocs.  Keeps the feet warmer when wearing without the liner.

These were purchased as indoor/outdoor slippers. I have used them to even run to the store in! They are extremely comfortable and warm. I have taken the lining out and washed them - make sure you follow the laundering instructions - they can't go in the dryer - and to remove the lining was quite easy!

I was pleasantly surprised. I wear size 8-1/2 C in shoes normally and they fit me perfectly. I'm so impressed with the soles. They feel like memory foam when you walk on them. Lots of cushioning and not like the Isotoner ones I've purchased at the stores. Of course I haven't bought any in a few years so maybe all slippers are like that now. I never really wash slippers so I'm not sure how they will hold up. So pleased I'll order another color.

I normally dislike wearing insulated socks because of their bulk. I like a thin sock. In years past the socks they made for big and tall men were not very comfortable. They were cheaply made socks sold at a premium price because they had an extra inch or so of material.

So I was not expecting much when I tried these socks. I was pleasantly surprised. They are the most comfortable socks I have ever worn. Since I have retired I try to spend a lot of time outdoors even when the weather is cold. These socks are so warm they have enabled me to stay out longer. I wear them daily in the winter and on very cold nights I have been known to wear them in bed.

These socks are pricey but you get what you pay for. Even my oldest pair of these socks still looks like new.

Very warm and very comfortable. To me, they are expensive but they are worth the investment.

I got these slippers for myself as the Chicago winters are cold and socks that were to keep my feet warm were not. The description of these slippers is accurate. Within 10 minutes of putting them on my feet were nice and warm, and I a happy camper. The faux fur feels really luxurious on your bare feet. I highly recommend these.

These are not only wonderfully warm, because of fluffy inside they feel much softer against the skin than wool or other thermal socks. The size is meant for many size feet. My husband is men's size 11-12 and they fit him fine. I'm a woman's 9-10 so the foot is technically longer than I need, but the heel curve is so soft and only very lightly shaped, that I simply pull the socks up to where the foot is comfortable and there's no bump or bulge.
At least from my experience, they're soft enough to fit comfortably a wide range of foot sizes, and the material is great. I've washed them in the washing machine without problem. I use cold water and relatively light wash. Haven't had them long enough to wash dozens of times, so don't know if they'd do better with a hand wash, but that would be easy if you're concerned. Already bought another set. Would be nice if they came in a dark blue also, but the dark gray is quite useful.

This is my second pair of these slippers and I've bought a few pairs as gifts too. The first pair lasted me 8 years. They are so warm and so comfortable. I usually wear size 8 or 8.5 shoe but have to get size 9 in these slippers and even then they are really snug when brand new. However, they stretch with wear so don't size up too far. When new, they are too tight to wear socks with, but that would be too warm anyway and it's nice to feel the soft sheepskin on your feet.

very warm I love them. They feel a bit heavy when you first put them on but you get used to it.

They are super warm and comfortable. They do run on the small side as they are packed full of insulation. They are exactly what i excpected from UGG. I would buy again if i need any more slippers, however due to the quality of these slippers i don't fore see having to buy any in the near future.

Very warm and comfy, and after I've broken them in for a bit I feel like I can wear these boots all day long. The outer sole of the boots can be slippery on ice (especially ice that's formed on smooth surfaces like granite), but since these boots aren't waterproof I wouldn't recommend prancing around in deep snow or ice with them anyway. Over all a great purchase for those really chilly days and for light snow.

They are so comfortable and warm.  The fur interior adds to the comfort and cushioning for my feet.  I absolutely love them.  Tick all the boxes and I am thinking of buying another pair so I have a back up when they wear out.

They are really warm and comfortable. I ordered a size larger and it was perfect. I order this once before and For the price, I went back and ordered all the colors as well as one for my sister inlaw.
