Ok, I too secretly love crocs and have had a bright orange pair for several years so I decided to treat myself to a pair of lined crocs.  Well, the soles are very odd, they are the thickest in the very center and and have rings that radiate outward so when you walk they either tilt to one side or the other. Take a look at the details page and you'll see what I mean.  I can't imagine why anyone would want this feature as it is tiring for your feet to try to keep balancing.  I just got them today in the mail and back they go, a huge disappointment. My 11 yr old son tried them on and said, "I feel like a clown on a unicycle".  Well said.
