These fit great, are very comfortable, and the tops are made of great material and are very well assembled. However, after just 3 weeks of indoor wear (on carpet and not even worn daily), the heals are already showing wear. I got these to replace another pair whose heals wore thin after 6 months and hoped that was just a fluke. Sadly, it's not. Based on past history and how these are starting to wear already, I'm sure these won't last me more than 6 months before needing replacing. Very strange considering they sell replacement inserts. I just don't get it. Customer service was very disappointing saying I must be dragging my feet when I walk (which I do not). It's very disappointing, because most slippers are junk. These are superior to most, but still need improvement.
