I have wide feet. My current shoes are:
SPD – Shimano ME7 (the latter model with yellow flash). Just wide enough.
Flats – Shimano. Plenty room, very comfy.
Running – Topo Athletic. I tried some Altra on but they felt too wide as to be unsupported. Topo are a wide but snug toe box and slender ankle too.
Walking boots – Raichle. Old now and they were bought out by Mammut so don’t know how they compare.
I struggled with Salomon Speed Ross, Scarpa boots, Giro bike shoes, Bont were too racey, never tried Lake but they look quite racey.
For casual, look at Fly. I have a pair of boots which are comfy but not in the slightest waterproof.
