This is usually what happens when you don't wear shoes. "Fashionable" shoes deform your feet and crush them up a bunch. It's why old people in rich countries have so many foot issues, especially bunions. Toes are naturally supposed to be spread out a bunch and radiate outwards, but historical western fashion trends were towards pointy shoes/feet, so that's what's the norm now.

There exist shoes that don't deform your feet though. Like another reply said, barefoot shoes are one. Those are hardly everyday shoes though, you'll have to search a lot harder (and spend a lot more money) to find "natural" foot-shaped daily drivers

He could get some bearfoot shoes.
