Something breathable like canvas but it is more durable than leather. The soles are as tough as possible while staying flexible enough to accommodate squatting. The soles are designed to be replaced multiple times without damaging the rest of the shoes.

It would have a composite protective toe, few to no seams, and laces that can snug it up to your foot if you tug them and hook them, but the shoes would stay on if you don’t do anything to the laces. Like, they just wouldn’t be as supportive without snugging them up.

It would have aggressive arch supports, or else come with several different inserts for different arch support needs.

Also, very wide toe box designed around normal toes, not squashing toes into a narrow or unnaturally shaped space.
