I have a pair of Specialist Clogs that I had worn out. I wanted a closed shoe type so I wanted to try these. I usually wear 7 to 7.5 and from the reviews, it stated they run a bit small, so I ordered the size 8. The first time I put them on, they were snug putting them on and around the ankle. They have loosened up a bit and are easier to put on and are no longer snug around my ankle. I am on my feet all day long, and usually by the end of the day, my heel is throbbing, but not with these. These are so comfy that I wear them every day for the pass two months with no pain. I am sold on Crocs! Now that spring is here I am looking for a new pair of Crocs.
