First off, the sandal is extremely cute but the only reason why I gave it 3 stars is because, like other reviews have stated, you need to have chicken legs in order to fit these!  I by no means have thick legs, nor chicken legs but it was sooo hard zipping it up.  Once I was able to zip it up, my legs felt like they were losing blood circulation.  I will try a half size up and see if that makes a difference.
