That would be sustainable in a gentrifying or high income area, as bespoke products are massively expensive. I've been purchasing custom made shoes for many years now, and it's not unusual to spend $500-1500 even for medium level quality (not peak quality, like Berlutti shoes[1]).
The stubborn fact is that economies of scale are a real thing, and so there is a limited market for paying bespoke prices for every day objects like shoes.
