I bought 2 pair of these sandals. I put the black ones on right away and have been wearing them a lot. Not out to the store yesterday as it's still too cold for bare feet.  I knew I would have to get used to the thong between my toes. I wasn't sure if I could. After the shoes were warmed by my body, the thong got more comfortable.
Today is Day #2 of wearing them and they are getting more comfortable as time goes by.
I love the shape of the shoe inside. They cradle my feet and, as a result, my feet don't slip and slide around.  Very nice.  And they are great to wear in the shower so I don't have to worry about falling down.

Long live Crocs!
