The new Brooks Ravenna 11 takes what you know and love from the 10, cleans it up and revamps the upper to be lighter, more form-fitting and more breathable. Back and even more seamless than before are the GuideRails Holistic Support System which naturally guide the foot through the gait process keeping excessive movement in check combined with the snappy and responsive BioMoGo DNA midsole. Neither sacrificing speed or support, the Ravenna 11 is ready.
