I purchased these shoes to go with a specific outfit I was planning to wear to a concert.  I have chronic pain issues with my back, and also have occassional pain in my legs, knees, ankles and feet, as well as swelling of the feet.  The event required some walking (several blocks at least) and the Crocs remained comfortable the whole time. They did not aggravate my pain condition, nor did they pinch, bind or rub anywhere on my feet. They look great on as well, not much at all like the old school Crocs.. nobody even noticed that they were Crocs until I told them!
