I have this same problem - and my feet grew 1/2 size with each baby!
Here are some options that I have or am considering getting for fall.

Superga
Unisex 2750 Cotu Classic
Sneaker (I just ordered these but can't speak to their comfort yet)

Franco Sarto 'Linden' Leather Bootie (I want these - hoping for a sale soon
Børn 'Pirlo' Boot (Women)

Earthies® 'Bindi' Flat (my local comfort shoe store recommended these as the most comfortable ballet flat they've ever seen)
Vans (so many colors and patterns - canvas, suede and leather! comfortable, no break in period - just need a no-show sock at first)
