I have really wide feet and I've had a hell of a time finding comfortable shoes. I tried the Prices but they weren't wide enough or giving enough in the toe box. I tried KSwiss but that didn't work either.
I tolerate the Babolat Propules for a while, but while they are excellent shoes, they also aren't really wide enough for me.
The only thing that works are the New Balance since they come in 4E. Some people claim durability issues w/ the MC 1005, but I wore through the Babolat's in less than 6 months (yes, they replaced them) but the NBs are holding up even better.
And I just got a pair of the NB 656s. These are awesome! Super comfortable and super supportive. And they look awesome too!
Give NB a try!
