"I own the Lunar and I absolutely love them. The are comfortable and I can run around town for hours running errands and not be tired. I have wide feet and tend to sweat ( sorry TMI ). The top part of the sole lifts and I can wipe them down to prevent the shoe smelling. I normally wear a 7.5 and got the 38. Its a prefect fit. I would not wear thick socks but a liner for comfort. The thicker sock made my toe stick up."
