I bought these to wear with my scrubs for work.  However, immediately upon receiving my order and trying them on, I quickly learned that I would have trouble with them if I'd kept them.  Right away, I felt my heels slipping out of the backs of the shoes.  It wasn't a matter of them not being the right size but rather the design of these particular Crocs.  I have numerous other pairs of Crocs in a variety of different styles, but while I wanted to love these, they got sent back right away and a different pair was ordered in their place.
