I have just the opposite problem. My feet are narrow. Check out the catalogs, nearly ALL advertisements are for medium and wide feet.
Redwing is about the only one I can get proper fitting shoes from.
Everywhere I work requires leather work boots, but not steel toes, it can be detrimental to electrical work, but there are tech toes.
Last time I hung around coal mines, though, it was steel caps and metatarsal protection as well.
Good luck.
