When you need the lightest, stiffest, best-fitting triathlon shoes to get the most out of your training and racing, slip on Pearl Izumi's Tri Fly Octane IIs. Weighing only 185 grams per shoe (in size 42), the Octanes feature Pearl's unidirectional carbon 1:1 Power Plates for awesome power transfer. And, their super-thin .9mm Second Skin uppers shed weight and feel perfect against bare feet. Plus, Pearl's huge Direct-Vents drain water quickly and allow air to circulate to keep your feet cool and dry. Inside, the lined mesh uppers also feel great on bare feet. And, the Octanes will get you through transitions in a flash, too, with Pearl's 1:1 Anatomic Tri Closures, heel loops and rubber heels and toe bumpers for walking traction.
