My issue I don't even know whether to describe it as length, width, or toe length.

Even if I can get a shoe that's wide enough across the metatarsal arch and narrow enough in the heel - rare as that is - even on most of those, the outsides of my first and fifth toes rub right at the end of the nail.

So if the toe box isn't really square, if a shoe is big enough, I wind up with this enormous triangle of empty clown shoe ahead of my second through fourth toes.

I may still have to find a pair of those Chacos in Wide - although I'm very hesitant about running in the country with open toes - and they sure are heavy. Can they be re-soled with lighter soles?
