A resilient polyurethane laminated material is combined over a comfortable mesh, resulting in reduced yield and providing long lasting foot support where it’s required. \u003c\/p\u003e\u003cp\u003eThe closure is fast and secure, powered by a microadjustable BOA in an Overcurve pattern. Overcurve is a shoe construction featuring a staggered collar that wraps around the ankle, tracing the natural misalignment 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.\u003c\/p\u003e\u003cp\u003eThe new, moderately stiff, R4 outsole strikes a balance between comfort and pedalling 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 channelling for temperature management. The cleat positioning is slightly further rear-wards compared to traditional settings, to optimize pedalling efficiency and reduce knee compression, especially well suited to very aggressive,  forward aero positions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOvercurve: asymmetrical construction that ergonomically conforms to the foot’s anatomy\u003c\/li\u003e\n\u003cli\u003ePU laminated mesh upper: enhanced ventilation with support where needed\u003c\/li\u003e\n\u003cli\u003eR4 carbon injected outsole: moderately stiff for efficient power transfer in comfort\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePU laminate over mesh upper \u003c\/li\u003e\n\u003cli\u003eSingle BOA\u003c\/li\u003e\n\u003cli\u003eR4 outsole – carbon injected nylon, stiffness index 7\u003c\/li\u003e\n\u003cli\u003eWeight: 221g (size 42)\u003c\/li\u003e\n\u003cli\u003eSizes: 36-48 (37 to 47 also in half sizes)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BikeParts.co.uk","offers":[{"title":"Default Title","offer_id":55572037075320,"sku":"TPR4OIR1K841047","price":136.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0021\/9434\/1977\/files\/22796-pm_e85cbc18-a58a-4254-913e-e8eafaaea67e.jpg?v=1780191186","url":"https:\/\/www.bikeparts.co.uk\/products\/fizik-r4-tempo-overcurve-47-iridescent-green-black","provider":"BikeParts.co.uk","version":"1.0","type":"link"}
