I usually wear a 6.5 but i got these in 6 since half sizes are not available. initially they were a little snugger than i wanted, but over time they either stretched or i got used to them. I primarily wear my crocs in the garden or rain, and the one downside of having such a snug shoe is if any water gets in my foot becomes a suction cup. Air holes on the sides would be nice. I didn't have high expectations for these shoes, so they are more than adequate for me. I love having decent looking shoes that i can get dirty and wet without ruining them.
