I tried a pair of WHITIN Men's Wide Casual Barefoot Sneakers | Zero Drop Sole from Amazon. In two months, they've become my favorite daily wear shoes. It's the first pair I've tried with a wide toe box, and it really makes a difference. Even better, only $40.

Skip the Whitin with the plastic. That model sucks (you're correct in that it digs into your foot).

I'd suggest this Whitin model. It's like their canvas sneakers, but instead of canvas its a mesh
