I will chime in that they are wide. But not as wide as I thought. I have never been measured, but definitely have wider feet, and was surprised with how wide the footbed was, and yet I still rubbed the sides a little. I go barefoot a lot these days, though, so likely my foot has spread a lot more than the average foot, and I *started* with a wide foot!
Anyway, I could wear them, fer sure. They were not at all restricting like most shoes! I was just surprised the sides of my feet touched at all given how wide they are advertised to be.
