I grew up in a car dependent area and moved to a walkable big city in my teenage years, and only then became aware that cobblers were still a thing -- in fact, in NYC, they're not an obscure thing, but as common as bank branches.
I think that's why there's a lot of people online who think cobblers aren't a thing anymore. They're from car dependent areas. If you drive everywhere, shoe soles don't wear out much faster than shoe uppers anyway, so it doesn't make sense to care. But if you move to a walkable city, you'll suddenly find it quite economical, since the soles wear out far faster, and the cost of a sole replacement is less than a new pair of shoes, so you might replace the sole a couple times before discarding the shoe.
