This shoe features a semi-rigid midsole plate for efficient power transmission to the pedal. The sole also features a special block tread pattern for optimal grip on different pedals and surfaces - cross grooves provide plenty of grip for different pedal cages and pins. Another exciting feature is the softly rounded outsole, which supports a natural heel strike and the rolling of your foot. And finally, the Mini-Power-Strap lacing system offers you an absolutely secure fit. Pedal system: Flat (specially designed for e-bikes).
