Warm feet and ankles > everything
Size: 10-11, Color: Red/Black Check
So, I know the foam is going to wear out quick on these, but they are so warm I dont even care. I will update when they start getting beat up. But so far these are great.
The soles on these arent the best. Its coushioned now, but even so my foot hangs off it. BUT, it is thick material and its keeping my feet and more importantly my ankles warm. Thats why I bought these. These isnt much on the bottoms to keep you from slipping hut what they have seems to be alright for now on hardwood floors. They fit true to size and are nice and stretchy, just beware the sole is a bit slim. For example my pinky toe hangs off it on both sides almost fully. Still a 7/10 would recommend for lounging around the house.

Warm, comfortable booties
Size: 12-13, Color: Red/Black Check
I would give these booties a 5 star because they are soft, warm, comfortable, high on my ankle and a color I appreciate. They are easy to slip on NOW. I say "NOW" because I have a deformed foot due to being broken. That foot was hard to get the bootie on. After 1 try in which some of the stitching came out; it's easy to put on.
The stitching came out far to easily. There are 3 lines of stitching. One line between the sole and 1st layer of polar fleece. That line has had no problem. The other 2 lines have each come out abt 3 inches.
I got size 12

Seams Separate Quickly
Size: 8-9, Color: Red/Black Check
They fall apart. The seams are terrible and almost immediately separate. Although they are warm and comfortable until stuff comes through the separated seams.

Meeting my expectations....
Size: 14-15, Color: Grey/White Check
I am a male with pretty large feet (Mens size 14US) and wanted some very warm slippers to wear around the house. I have nerve issues in my toes and if I don't keep my feet very warm they start to hurt. I wanted something both comfortable and warm. I received these a few days ago and so far they have done a great job at keeping my feet warm. The linings are thick and fluffy and the bottoms feel like they have a memory foam inner sole in them. The tops can either be worn up or rolled down. The actual soles are a soft leather-like material. They are thicker than normal cloth, but not hard like rubber soled slippers (I actually wanted something that was more of a slipper and less of a "shoe"). The only down side is that they don't really seem to have a left and right to them (both slippers seem identical), and for awhile no matter how I wore them, they felt a bit like they were on the wrong feet. However, they seem to have formed themselves to my feet and now (through wearing them) it definitely feels like there is a left and a right. I don't know how long these will last, but they were not expensive, so if I get a few months of wear from them, I will be happy and will just order another pair when these wear out. They aren't the most attractive slippers in the world, but they aren't horrible looking and they are very functional.
