I wear a 5 1/2 and usually buy a 6. I had to return these for a 5. Hope they fit.

Too bad I didn't have extra shoes with me the day I wore these to work. My heels throbbed, the top of my foot swelled. First pair of Croc's that need to be broken in. Bummer.

I find that these run large and wide. Back and sides come up very high. They are certainly cute, but I wouldn't rush out to buy another color.

CON: I usually wear a 6.5 to 7, so I bought a 7 per the instructions to size up. They were HUGE. I have medium width feet and they were swimming in these shoes. I purchased the khaki color, and... they look like orthopedic shoes. (I'm sure the darker colors are better.) As soon as I put them on I felt like I had frumpy feet, which is ridiculous. I tried them on in front of my mother in law and husband, and they actually grimaced. Maybe if I was wearing them under long jeans they would look alright, but my hope was to find a shoe I could also wear with shorts or skirts. PRO: They did feel very comfortable on, although I didn't do a lot of walking. If you have a wider or "fatter" foot you'll probably enjoy the fit -- the top strap was very high, leaving plenty of room. The shoes were also very light (per usual with Crocs) which was nice.
