In reply to Ellanah: Some Scarpas and some Sportivas fit my very fat feet. I also recently had a pair of Mammut Velpros that were an excellent fit.
Boreals have always been a disaster for me - way too narrow, and 5.10s not great although that is often more to do with my ankle bone rubbing.
Oddly some rather twisted designs fit my wide feet well, hence my current good shoes are Sportiva Miura lace, whilst the Katana laces (less twist) were a bad fit.
