This shoe has a «Strato» sole and therefore a higher Rebound-Effect. The «Strato» sole is designed to roll better in the backfoot area than previous kybun soles. 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 for poor postures and misalignments and the full-length sole profile with larger contact area to the ground ensures optimal grip on any surface.
