When you need the lightest, stiffest, best-fitting equipment to get the most out of your races, slip on Pearl Izumi's Tri Fly Octane Shoes. Weighing in at only 185 grams (in size 42) per shoe, the Octanes feature Pearl's 1:1 Power Plates that support your feet for full power transfer. The uppers are made of one-piece Clarino Rovenica with huge Direct-Vents that drain water quickly and allow air to circulate to keep your feet cool and dry. Inside, the lined mesh uppers feel great on bare feet. And, the Octanes boast details designed to get you through transitions in a flash, such as a 1:1 Anatomic Tri Closure, heel loops, and rubber heel and toe bumpers for traction while walking.
