The inside furry part is definitely not as thick as the ones I got from Costco a few years back. At first I thought they were too short in the length and I was tempted to put them right back into the box.  My toe was hitting the end in an uncomfortable way.  After wearing them a bit, they seemed to be fine (lengthwise.)  After wearing them for 3 times, I realized they just were not comfy and I reached inside the heel area, and the fur was completely matted and balled up- ugh. Really, after just 3 times??? (Also, for those of you interested in removing the bottom liner to put a shoe insert underneath it for arch support, the bottom is glued down.) I think these should be in the twenty-dollar range, then they might be acceptable as a slipper for around the house. These are soooo getting returned.
