Built off of the success of the original Kestrel, the Kestrel Lace W is designed to transfer power to the pedals as efficiently as possible with a classic lace closure, lower total volume, and tighter fitting heel. The Kestrel Lace W features a Stealth® S1™ outsole and wider cleat interface that is compatible with every type of SPD pedal. The shank of the Kestrel Lace W is nylon, making it about 15% less stiff than the Kestrel, while an EVA midsole provides excellent shock absorption.
