The shoes are lightweight and comfortable; however, I think they run about a 1/2 size large. Maybe has to do with about how the toe is raised up on the end. Mine going back for a 7. I think they are not work this much money, but since I've never purchased designed shoes before, I'm going to keep these and treat myself. They do give your legs a workout and make your posture better. This is my first pair by Earth Coutoure; hoping to get some more of this brand at a cheaper price.
