I bought the Acorns for $34 and they lasted a year before they were worn out on the bottom and filthy. At least they were comfortable. These have a hard rubber lip all around the part your foot steps on and they actually hurt when walk on them. Some idiots in China make these with without ever trying them on to see if they are comfortable or stay on your feet. The opened toe design is great, but these are the worst slipper I ever wore and I am shocked that they other reviewers did not warn me. It will cost half the price to ship them back but I am going to call and complain and buy another pair of the Acorn. Stay away from these stupid slippers!
