The new Cyclone Speed 4 is very lightweight, but without compromizing on grip and stability. This perfect allrounder offers players a soft responsive midsole and good flexibility thanks to smooth bending grooves strategically placed in the forefoot. • Particularly lightweight due to the reduction of rubber amount. • A better flexibility thanks to smooth bending grooves on the outsole. • The fully flat sole brings an increased level of stability. • The rounded outsole enables very smooth heel strikes.
