New Balance520 V8 Mens Running Shoe

Do these have a removeable footbed to accommodate orthodic inserts?

Are these 520v8 neutral pronation?

Weirdly enough new balance 520 v8 is far less comfortable than v7. anyone else noticed that?

I wear an 11.5 in Nike. I have purchased NB 11.5 before and they are "short" in the toe box. Should I purchase a 12?
