Built on a women-specific last, this is one of the few really excellent mountain bike shoes for female cyclists. TPU film and texture mesh are thermo-bonded together to create Synchwire, a single-layer upper that conforms to your fit, provides phenomenal structural support and ventilation. 3 compression-molded Velcro straps give you tried-and-true tightening and support. Injection molded outsole with insert molded rubber treads and inserts for toe spikes provide power to the pedals and sure-footed traction off the bike.
