I’ll stick my oar in too, not only wide, but bunion and hammer toes to add to the fun. 12.5UK size as well which can be a little limiting.
Agree on NB wide trainers being pretty good.
Agree on 5.10s becoming useless (but, fear not, if you need wide and big shoes Specialized canvas flats are awesome).
Agree on Innov8 being OK but not lasting well, though even the ‘wide’ are very style dependant, and even the widest I have are quite tight.
Sketchers wide are OK, but I find, as a big lad, they offer little to no support so make my feet ache if I’m doing any walking in them.
Keen I agree are very good, but now no longer sell/ship to the UK from europe, so that’s a right pain in the tits.
Completely coincidentally, @dantsw13 , I just found Fitville. They are dangerously close to being a bit ‘NHS’, and they do size up BIG, but I followed their fitting guide and got a pair of general smart ish trainers (on Friday) that are the most comfortable shoes I’ve ever owned. And they are not expensive.
