To avoid anyone's future confusion, I should clarify that Moab is a very popular model/line from Merrell.
I have a very old pair of Chaco sandals that I used to wear all summer. I haven't worn them in years because they're incredibly heavy compared to my current preferred Keen sandal, which also has the advantage of a closed toe--I'm at least a little prone to stubbing it. They were always extremely comfortable, though, so I may take a look back at their shoe options. Last time I checked they were pretty limited. Still a sandal company at heart--which I understand.
FWIW, definitely try some Keens next time you're shopping for a pair of boots or hiking shoes. The Targhee line is still pretty close to the same shape as their older signature wide toe box. I think the Targhee III is a little narrower, but still fairly wide compared to some other brands.
Asics have usually been my other standard casual shoe brand, but I haven't tried on any current models to know if they've changed their general sizing and footbed shape.
For @PaulT00 , I see that you're in England, so this may not help, but I've had decent luck with Allen Edmonds for dress shoes. My foot is a pretty proper US 9EEE on the Brannock, and with most of their lasts, that's the right size. Their classic 65 last is a little trickier for me because it's got a longer, pointier toe and not as generous an instep as I prefer. The 201 last has more volume in the instep and toebox, so I have done a half size smaller in it in one pair. Sock choice has a big effect also.
