The Pearl Izumi Men's Tri Fly Octane is a viable candidate for the most advanced triathlon cycling shoe ever.
The Tri Fly Octane combines extremely light weight, superb fit, industry standard ventilation, good drainage, unique materials
and an evolved design in one shoe. We don't know of a better triathlon cycling shoe from any brand.
The sole is autoclave molded full uni-directional carbon fiber. The fiber orientation provides performance enhancing stiffness
over the cleat mounting area but vibration and pressure disbursing energy absorption over the arch, heel and forward toe to prevent
foot fatigue. This gets you to the run transition with fresher feet and less "club foot" running off the bike. Dual I-Beam molding
of the carbon fiber sole resists torsional flex, improving power transfer and preventing foot fatigue, especially on smaller pedal
The sole has excellent drainage and ventilation, a real-world concern for long triathlons. To compliment the sole ventilation the
upper is completely unique, using ultra-fine mesh throughout the entire forefoot reinforced with an ergonomic exoskeleton of structural,
non-stretch polymer reinforced synthetic fabric. The combined laminate of advanced fabrics provides the best fitting, and best ventilated,
triathlon cycling shoe we have seen from any manufacturer.
Pearl Izumi has re-engineered the high speed, single Velcro closure on the Tri Fly Octane by re-tooling the main,
1.75 inch (45 millimeter) wide closure at the saddle area. This main closure provides high speed donning in T1, especially
for advanced triathletes who leave their shoes clipped in for the fastest exit from T1. The closure wraps the entire central
section of the shoe, converging with a full-span component that locks the foot to the shoe sole for optimal power transfer
while distributing pressure over a larger area than any tri shoe for better comfort. This closure design is so unique it is
actually patent-pending. A small, secondary forward Velcro closure adjusts forefoot volume for precise fitting.
A giant heel tab facilitates pulling the shoe on while rolling for the fastest exit from T1.
We weighed the Pearl Izumi Tri Fly Octane at 196 grams (6.9 ounces) on our scale for a size 43 shoe. By comparison our most
popular mid level tri shoe from LG weighs 298 grams, about 35% heavier than the Tri Fly Octane. The reduction in rotating
weight on the Pearl Izumi Tri Fly Octane is noticeable.
The shoe is very low stack at only 6.5 mm sole thickness and is sold in sizes 38-49.
Three hole compatible for Look, Shimano SPD-R (Road), Time, Speedplay and most other popular road clipless pedals.Features and Benefits:
