I am a big fan of crocs. I have the beach and cayman style. I was sad to pack them away for the winter so I purchased a pair of Aspen Crocs. I have to say that the first time I wore them, my feet got so hot and sweaty that they defeated the purpose of the shoe. There is no way for the air to escape. As a result, your feet may get very sweaty.  Make sure you wear socks, the ankle ones at best. This will absorb the sweat. Otherwise, you could end up with itchy feet...or athletes foot! (Sorry for the honesty). I was a little disappointed with these shoes. The backs have no way of keeping the "Elements" out of the shoe. The front toes get cold if you stand in snow.  Make sure you order up, these tend to run small! (At least for me they did).
