Double boa racer shoe with carbon outsole and volume control fit for a combination of comfort and performance.

The R3 Aria’s Microtex upper is hard-wearing, light, and resilient with enough flexibility to ensure comfort for every rider’s foot, but strong enough to withstand the demands of racing - without any weight penalty. The diamond-shaped laser-cut perforations help temperature management and breathability.

The laser perforated mircrotex upper is breathable and cleans up really well.

Volume control - the lower Boa controls toe box volume. The offset position means the front of the shoe wraps across the foot making it much more adaptable to different foot shapes.

Vented carbon outsole with replaceable heel tab.

Heel gripper on the inside of the shoe.

Why use BOA?

Glove-like fit: it provides custom comfort with smooth, even closure and no pressure points.
Powerful closure: once locked into place, BOA reels and laces stay that way.
Micro-adjustability: BOA reels offer seemingly infinite degrees of fine tuning.
Quick on, quick off: BOA saves time when seconds count.
On-the-fly adjustment: get easy, one-handed adjustment with a quick turn of the BOA dial.
Durable: made from aircraft grade stainless steel, BOA laces are stronger per gram than tank armour.
Lightweight: BOA closures shed water, mud and ice, shaving precious weight.

Adjusting the BOA closest to the toe will alter the fit and distributed pressure around the foot, enhancing comfort and performance.

Adjusting the BOA dial will alter the fit of the heel cup around the foot, increasing power transfer and maximising performance.
