I started off this day by taking an hour long power walk in my new Reebook Easytones. I thought I should try them out for a while and then review them here. So far I don't feel any particular muscle pain in the thigh or butt area. However these are very comfortable shoes, so even if they don't keep their promises, they are still very good shoes to walk in. Maybe I should take longer or more intense walks, although I thought I would be getting some muscle ache, I've been a total slacker lately!
