Blending a barely-there feel with unmatched performance and breathability, the incredibly lightweight Pearl Izumi Tri Fly P. R. O. V3 Shoes are designed for serious triathletes in competition where every gram matters.

The Integrated Carbon Power Plate is both featherlight and ultra-stiff for optimized power transfer, and the Unibody construction does away with the traditional lasting board design to give you maximized pedal efficiency through a super low stack height. Dual-density EVA comprises the insole substantial arch support where you need it, while the off-center heel loop makes for an easy on and off in critical transitions.
