These just arrived at my house in yellow, and right out of the box they fit perfectly and are extremely comfortable. Amazing traction. Stay on the foot with every step, something a ballet flat you wear with bare feet sometimes cannot accomplish. I wear an odd size (10.5). Most manufacturers don't bother making it at all -- just skip from 10 to 11. Love Merrell for not neglecting us in-betweeners. Will come back with an update after I wear them for a full day!
