My feet: size 8.5 - 9, somewhat wide forefoot, somewhat narrow heel, moderate right foot bunion, flatter arches, pronate when walking.

Purchased 1/2 size up based upon some reviews that I read.  Really glad I did.  These are my work shoes (hospital, 10 hour shift on my feet) and they were very comfortable with socks I wear with tennis shoes. They would be too loose with stockings.
