Reviews here said they ran true to size, so I ordered what I usually wear in Keen's--7. However immediately upon putting them on I could feel that my toes were jammed up in the front.  I really liked the look of the shoe and otherwise they seemed comfortable so I exchanged them for the 7.5 and these are perfect with plenty of toe room, maybe a little loose at the heel but I'll be able to wear them with hiking socks. They seem a little stiffer than I'd like but I'm hoping they loosen up.
