These are GREAT. I’m a very true 8.5 and I got the 8.5. Admittedly they felt a bit small at first in the store (I ordered online) but the 9 wasn’t available so I kept them and was hoping for the best that they’d start to fit me! Well, I’ve been wearing them around the house all afternoon and can tell I made the right choice keeping the 8.5! The fur is squishing down around my feet perfectly and I know they’re just going to start fitting better and better the more I wear them… and I don’t plan on taking them off anytime soon! They also feel like high quality shoes so definitely worth it! Don't wait on these - they’re awesome!
