Only experience I have is with my bespoke cowboy boots.. These were pricey, but they fit like a glove. I also got to pick the hides, and design the uppers, and have the heel hight/angle as I wished..Well worth the extra simply for the comfort..with me it was the opposite of big feet, narrow, but high instep and arch.
FYi.. Ostrich lowers, kangaroo uppers..

Cheers
Harold
