In reply to tom f:
I have really wide feet at the front, and a narrow ankle, which is a pain in the arse for climbing shoes!
I found the 5.10 velcros to be pretty good width wise. The whites are pretty narrow, as were the pinks, although weirdly my pinks feel pretty good, my foot just bulges out a bit further than the sole covers.
Possibly also try la sportiva miuras / katanas or scarpa stix / booster / lace ups as those all seem pretty wide at the front
