Building on the success of the original Kestrel, the Kestrel Lace has been developed to transfer power to the pedals as efficiently as possible with a classic lacing system. The Kestrel Lace Women's features a Stealth® C4™ outsole with SPD compatibility, allowing it to work with all types of SPD pedals. The upper of the Kestrel Lace is made from nylon, making it about 15% less stiff than the original, while an EVA midsole provides excellent shock absorption. Highlights of the 5.10 Kestrel: • Sewn outsole made from Stealth® C4™ rubber. • Compatible with all SPD pedals. • Perforated upper material in the toe area with mesh tongue for added breathability. • Non-slip heel cap for increased torsional stiffness. • EVA midsole with nylon upper. • Polyurethane (PU) coated synthetic upper material. • Sleek, flat design. • Velcro closure. • 384g per piece (size 7US). 5.10 KESTREL LACE W grey five/shock cyan/core black 4 / 4060509358466
