Awesome slippers
Size: 14-15, Color: Fleece Black
Very warm and comfy, I have sasquatch feet (14 wide) and the 14-15 size fit great with plenty of room. It's very hard to find slippers in my size and these are awesome, especially for the price! Definitely recommend these, I've been wearing them pretty much daily around the house during this especially cold northeast winter and they're holding up perfectly.

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.
