My mom has been bugging me to get a pair of crocs for months (she has a pair of the original mule style and loves them).  But I wanted more of a sandal - so I thought I would try these. And she was right, I love them.  I am not sure they are toning anything - but they are very comfortable and I wear them everywhere. (I have since bought two more pair of crocs in different styles - I am addicted).
