The all-new Surge.

Unique composite sole technology combines stiffness in the forefoot, where most of a rider’s power is applied, with strategically engineered flex to reduce tension and strain in the lower leg. The result is enhanced power transfer, a more precise fit, and optimized efficiency. 

Works in harmony with the ExoBeam to produce a unique 360-degree foot enclosure for customizable fit. The design optimizes foot support by pulling up on the arch, which helps improve power transfer, comfort and efficiency.

Microfiber synthetic upper offers superior support at an extremely low weight while conforming to virtually every foot type. A removable dual-density EVA insole with forefoot ventilation features TransTextura Plus antimicrobial technology to help promote a balanced foot climate.

The award-winning, patented Boa system provides custom comfort with smooth, even closure that is lightweight, durable and intuitive. A quick, convenient turn of a knob lets you dial in the perfect fit without the added weight and hassles of other closure systems.

Injection-molded TPU elements in both the heel and toe help protect the carbon ExoBeam plate from wear while off the bike.
