Hey there! I have a pair of Reebok Easytones, but haven't worn them to the park. I have, however, worn them while walking my dogs. I would NOT suggest wearing them to the parks. Not that they aren't SOOOO COMFY, but after walking for a while, I began to get shin splints. I don't think having leg cramps in the Happiest Place on Earth is worth toning your rear.
