Road Shoes Tempo Overcurve R4 Black/Black 45

Overcurve r4s classic esthetic belies an advanced construction technique. A resilient polyurethane laminated material is combined over a comfortable mesh, resulting in reduced yield and providing long lasting foot support where its required.

the closure is fast and secure, powered by a microadjustable boa ip1 dial in an overcurve pattern. Overcurve is a shoe construction featuring a staggered collar that wraps around the ankle, tracing the natural misalignment of the ankles two bony protrusions: the lateral and medial malleoli. The result is an asymmetrical shape, with the throat of the shoe curving over the foot from its outside to its inner side.

The new, moderately stiff, r4 outsole strikes a balance between comfort and pedaling efficiency to make it a true all-rounder. R4 has a new, even lower profile, and is structurally optimized with a composition that includes 15% infused carbon fiber. The r4 outsole provides efficient ventilation and internal channeling for temperature management. The cleat positioning is slightly further rear-wards compared to traditional settings, to optimize pedaling efficiency and reduce knee compression, especially well suited to very aggressive, forward aero positions.
