The R4 Tempo Overcurve Wide is an all-round road cycling shoe designed for various cycling activities. Whether you're joining a weekend group ride, training daily, or participating in a granfondo, this shoe is made to perform. The advanced construction technique used in the Overcurve R4 ensures durability and comfort. It combines a resilient, polyurethane-laminated material with a comfortable mesh to reduce energy loss and offer long-lasting foot support.Designed to cater to riders with wider feet, the R4 Overcurve Wide provides a higher volume fit and more room in the forefoot area. The shoe closure system, called Overcurve, is fast, reliable, and secure. It is powered by a micro-adjustable BOA IP1 dial in an overcurve pattern. The collar of the shoe is staggered around the ankle, following the natural alignment of the ankle's bony protrusions. This asymmetrical shape provides a unique fit, curving over the foot from outside to inside.The R4 outsole is moderately stiff, striking a balance between comfort and pedalling efficiency. It is structurally optimized with a 15% infused carbon fibre composition, resulting in a lower profile. The outsole also features internal channelling for efficient ventilation and temperature regulation. The cleat position is slightly further towards the heel, which optimizes pedalling efficiency and reduces knee compression, especially for aggressive forward aero riding positions.Specifications:- PU laminate over mesh upper- BOA IP1-B dial closure- R4 outsole with carbon injected stiffness index 7- Weight: 232g
