I bought a pair of the Crocs sandals (Nile, I think?) for our trip last May. I loved how they felt, and how light they were, but after one day at the parks I had the BIGGEST blister on the ball of my foot! And I don't EVER get blisters! That put an end to my Crocs fascination. I had to alternate between a different pair of sandals I had brought and my tennis shoes for the rest of the week...that blister HURT!
