I bought these slippers recently, I am working in Afghanistan in the mountain area, where it is getting cold (I'm from So. Cal)i work on a Army base, where i have to walk to use the bathroom or shower, and the terrain is very rocky, they laid down gravel to help with dust, didn't really help only made it hard to walk. these slippers handle the terrain with no problem, they are so warm and comfortable, i wear military desert boots 12hrs a day 7 days a week, so i look forward to putting these on. I would highly recommend these to anyone, worth the price for sure!!!!
