I bought the larger swimming goggles, as I with the other model (which also super is) always had extreme dark circles, which swim after an hour, almost twice as long as needed to disappear again. These glasses also leaves edges, but which disappear quickly by another supporting surface and are not pressed directly under the eyes. Otherwise, it keeps very tight, depending on how much you sweat, they steam up, but that's in almost any spectacle like this. Conclusion highly recommended.
