The top-of-the-line Sidi Women’s Genius 6.6 Carbon Bike Shoes help you stay ahead of the peloton. Sidi’s patented carbon sole varies in thickness, which makes these shoes lightweight and super stiff but allows for a bit of give in certain areas so your feet don’t feel tortured on brutal mountain rides. The Heel Security System—an adjustable plastic band at your Achilles—locks your heel down no matter how hard you pedal. The breathable, supple uppers have mesh inserts to bring air to your feet, and an instep buckle lets you tweak the fit on the fly.
You’ll get thousands of miles from these high-performance bad boys—er, girls.
