I have what I call "duck feet" with really wide, short toes with space between them when I stand.  My pinky toes curl under on the tips, and the sides of them stick out, preventing me from wearing anything narrow in the toe area.  These shoes are the worst for my feet!  I'm disappointed, because these would go with so much I wear, but every time I wear them, with or without socks, they absolutely smash my pinky toes and give me blisters.  I even cut the elastic hoping that would help, but it did little to expand the narrow toe space.  I have several pair of other Crocs and love them all, and thought these would make a great addition.  Nope.  So sad. :(
Note:  After I wrote this review I removed the elastic completely with scissors.  I also threw them in the dryer for about three minutes and wore them with thick socks until they stretched out.  Now they fit like a dream.  My only regret is that I couldn't keep the elastic...it made the shoes look better.
