Built for maximum pedal power, Pearl Izumi's Octane SL III Road Shoes pack a cornucopia of speed-boosting technology into an ultra-lightweight package. Weighing in at only 195 grams per shoe, the Octanes boast Pearl's 1:1 carbon soles that are anatomically shaped to support your feet for premium pedaling efficiency. The uppers are made of one-piece Clarino Rovenica with huge circulation-enhancing Direct-Vents that keep your feet cool and dry. Of course, the fit is absolute perfection—the Octanes conform to your feet straight out of the box. And, the Octanes utilize three Velcro straps for easy on-the-fly adjustments as well as rubber heel and toe bumpers for traction while walking.
