The [shoe] has a Strato Outdoor sole and therefore a higher Rebound-Effect. By modifying the sole geometry of the Cumulus, the Strato Outdoor creates an even better walking feeling and rolling performance. In addition, the sole has a lug-soled profile for ideal support on rugged and loose ground. This sole is suitable for all types of surface due to increased traction and lateral stability. This type of sole offers maximum effect as well as the ultimate in training performance and absorption. The foot pressure is evenly distributed and the power supply is optimised. The elastic and springy material compensates poor postures and misalignments by stretching the posterior muscle chain with each step and the full-length sole profile with larger contact area to the ground ensures optimal grip on any surface.
