I wore these shoes outside so cannot return them. At first, I thought they hurt the tops of my toes a little. After wearing them, they hurt tops of my (rather elevated, joints more bumpy than when I was younger) toes a lot! I'll try thinner socks. I also bought the Merrell Jungle Slides and they are super comfortable. Too bad about these as they are pretty, great color, good price--but I won't wear them much and will probably give them to Goodwill. Every step I made in them the other day hurt.
