I wear 11s as my toes are just over 10.5s. These are still a little cramped in the toebox. But I only run in them and don't really wear them other than 20 minutes at a time. I've had no discomfort when running, even with the aforementioned.

They're plenty breathable as the entire upper is all an open, moveable mesh. It does seem like it's glued to the bottom so I'm not sure if they'll hold up 3 years like my last Nike's did.

The orange is a bit too construction-orange for me, but hey, good safety color for evening jobs.

All in all they'll do me fine.
