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

Size 13 (not 13-16)
Color: Gray Navy, Size: 13-16
I have a size 13 foot and these Winter Socks/Slippers just barely cover the length of my foot, so if you are over size 13 these will be too small_ they are well made and insulated_ they look nice, just like the pic, and I can go from my house to the my car in the snow without the bottoms getting wet_ they are cozy without my feet getting hot_ just wish they were a half inch longer on the foot size to be a more perfect size 13_ they feel about 12-1/2

Awesome but loses shape
Color: Long Black, Size: 10-13
This is comfy and keeps my feet warm but definitely doesn't hold shape good to wear indoors but don't think about walking long distances.
