It's lightweight yet responsive, turning your footstrikes into propulsive launches without the drag. Paired with the bottom Helion foam and CloudTec elements, it balances speed with enough composure for daily miles, keeping you light on your feet even as fatigue creeps in. Updated stack - 37mm heel, 31mm forefoot - adds subtle protection while preserving that grounded, high-cadence feel you need to stay sharp.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNylon Speedboard Propulsion\u003c\/strong\u003e Infused with glass fibers, this nylon-blend Speedboard runs full-length for springy, powerful forward drive that's flexible enough for training but stiff where it counts. It transforms energy from heel to toe-off, amplifying your natural gait without the rigidity of carbon plates. The rockered shape enhances transitions, making fast intervals feel smoother and more explosive - perfect for when you're chasing splits or building speed. It's the backbone that lets everyday runners tap into pro-level efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngineered Woven Mesh\u003c\/strong\u003e Ultralight recycled polyester mesh upper secures your foot with breathability that fights heat on long hauls, while the redesigned toebox offers roomy forefoot space for natural toe splay during aggressive paces. Snug midfoot locks you in, average heel fit prevents slippage, and large logo with wrap-around grip pads nod to On's racing aesthetic. It's built to feel fast, keep you cool, and look dialed in Alloy Rock grey.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"On","offers":[{"title":"UK 7.5","offer_id":50662134251577,"sku":"3MF10113295-UK7.5","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 8","offer_id":50662134284345,"sku":"3MF10113295-UK8","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 8.5","offer_id":50662134317113,"sku":"3MF10113295-UK8.5","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 9","offer_id":50662134349881,"sku":"3MF10113295-UK9","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 9.5","offer_id":50662134382649,"sku":"3MF10113295-UK9.5","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 10","offer_id":50662134415417,"sku":"3MF10113295-UK10","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 10.5","offer_id":50662134448185,"sku":"3MF10113295-UK10.5","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 11","offer_id":50662134480953,"sku":"3MF10113295-UK11","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 11.5","offer_id":50662134513721,"sku":"3MF10113295-UK11.5","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 12","offer_id":50662134546489,"sku":"3MF10113295-UK12","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 12.5","offer_id":50662134579257,"sku":"3MF10113295-UK12.5","price":23999.0,"currency_code":"INR","in_stock":true},{"title":"UK 13","offer_id":50662134612025,"sku":"3MF10113295-UK13","price":23999.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/2397\/3945\/files\/1_2025_11_13_T171826_599_d72b7da038.webp?v=1791247308","url":"https:\/\/offmarc.com\/products\/on-running-cloudflow-5-alloy-rock","provider":"OFFMARC.","version":"1.0","type":"link"}
