Just got my first pair of crocs last night. I got the beach in khaki. I wear a show size 7 and got the small-6/7. I am debating about whether I should have got the medium. My toes don't touch the ends, but the top of my foot touches the shoe. I tried on the mediums and felt like they were just huge though. Should I exchange them or is there a way to stretch mine a little?
