I have size 13 feet and these fit very nicely! The plastic sole tread dots (for lack of a better description) goes all the way back and covers my heels completely so my hope is the heels will last longer. I don't yet know about the durability of these (only had them for a couple of weeks so far) so didn't give the durability rating a full 5 stars, although these may last pretty long. Half of my home is not carpet (tile & vinyl planks) so will be a good test of these. So far no visible wear.They are very soft and comfortable on my feet, and not too hot or too cold. If you tend to have really cold feet these might be a little thin, but they are just right for me.
