These boot slippers are awesome!
Color: Long Black, Size: 10-13
Love 'em!
FINALLY found these after lots of searches.... I wanted "boot" type slippers FOR MEN, so in the cooler/colder weather my ankles stay warm, as well as my feet. (It's easy to find them for women, but for some reason pretty difficult to find them for men.) Well, Amazon must have added these recently, because I had checked a number of times this past winter/spring to no avail.
At any rate, these are GREAT! I had worn out another somewhat similar pair I had found on Temu a while back, but they were rather floppy and really too large and wide for my feet. After a year or so they had worn out, so I started searching anew, and found these on Amazon. These fit just great and are very well made, having a thick fleece and padded sole inside and a non-slip sole on the outside.
Very, very comfortable! Just what I wanted, and kudos again to Amazon!

Not durable, cheaply made for big guys 6’4 235lbs
Color: Gray Navy, Size: 13-16, Color: Gray Navy, Size: 13-16
Don’t recommend for men. Boys maybe but not men. I wore them twice for about 3 hrs before bed. Went to put in the 3rd time and they ripped. It’s literally a small sheet of Sherpa from the shoe and plastic wrap. I also got the bigger size and they still don’t fit right. I bought these right before my trip upstate during the holidays, because I live in Florida. I paid $20+ for these, hoping they would be good. 1/10 recommend
