I can't say enough about Crocs Cleo sandals. They're not dressy, but they sure are comfortable. You just slide your foot in and go. They are made of some kind of rubber or plastic (or possibly both) but they are sturdy and you can even wear them in water. I have Cleos I've had for 5 years that are a little worn, but still look good and are wearable.I bought new Cleos recently and I notice they had slightly more room in the straps. The older versions of the shoes could become a little tight if I wore them in hot weather and my feet were swollen. They have good shock absorption, and there are little raised bumps on the inner sole. I like them, but some people might find them slightly irritating. I wear my Cleos for short walks. They're not meant for marathon walkers, but they hold up well during exercise.I have bought other Crocs sandals. I liked them, but not as much as Cleos. My only complaint is that the Shoebuy site is almost always out of my size sandal!I highly recommend this shoe for people who want a simple sandal for knocking around in.
