Pearl Izumi Expedition Pro Shoe Efficiency for any adventure Helping riders push their limits, these Pearl Izumi Expedition Pro Shoes are the lightest, stiffest, and most efficient off-road shoes Pearl Izumi makes, for riders who want to get the most out of every gravel ride and fast-paced ride on mixed terrain. The Expedition Pro Shoes inject road bike shoe pedaling efficiency into the world of capable gravel shoes, with the 1:1 EX PRO Carbon sole, a stiff and lightweight carbon fiber-infused midsole for top-level pedaling efficiency without sacrificing capability for the odd hike-a-bike sections. The Expedition Pro features a rugged outsole with TPU lugs for increased grip off the bike, while a reinforced toe bumper shields from rugged roads and trails. Keeping it all together, the dual BOA(R) Fit System with L6C dials allows for dual-zone fit adjustment on the fly, for a secure, comfortable fit wherever the ride leads.
