OVERCURVE
Shoe closure is fast, reliable and secure, powered by a micro-adjustable BOA® IP1 dial in an Overcurve pattern. The Overcurve shoe construction features a staggered collar that wraps around the ankle, tracing the natural alignment of the ankle’s 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
R4 OUTSOLE
The moderately stiff R4 outsole strikes a balance between comfort and pedalling efficiency to make it a true all-rounder, featuring a lower profile structurally optimized with a 15% infused carbon fiber composition. The R4 outsole further provides efficient ventilation with internal channelling for effective temperature regulation. The cleat is positioned slightly further towards the heel compared to traditional placement to optimize pedalling efficiency and reduce knee compression, especially suited to aggressively forward aero riding positions.
