I have bought some really high quality boots and shoes off eBay, barely worn, at rock-bottom prices. I wear a EEE width, most mass-marketed footwear makes everything in a D width(med), a one-size-doesn’t-fit-all solution. Occasionally those same guys will market what they call W or Extra Wide, but those are at best an E width.
So, I buy Allen Edmonds shoes and boots, Redwing work boots, and Danner hiking boots. All American-made, different lasts to fit different feet, and many different widths. I never pay full price for anything, always prefer used to new.
