The Cloudboom Strike LS is built for race day with a carbon fiber Speedboard, dual-layer Pebax midsole and a LightSpray upper that weighs almost nothing.

A single 1.5 km filament is spun by robot into a seamless, elastic mesh upper—no laces, no seams, no hot spots. At just 30 g, it's the lightest upper On has ever made. It fits like a second skin, breathes well and moves with your foot rather than against it. It also happens to emit 75% less CO2 than On's other premium uppers—fast and responsible.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMidsole:\u003c\/strong\u003e Two layers of Helion HF hyper foam sit underfoot, delivering the kind of energy return and impact absorption you need to feel strong in the later miles of a race. Sandwiched between those layers is a pre-shaped carbon fiber Speedboard that loads and releases with each stride, adding a powerful forward propulsion that makes fast paces feel more sustainable.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutsole:\u003c\/strong\u003e Ground contact is maximized in key areas for better traction at race pace. When you're pushing hard through a turn or opening up your stride on a straightaway, the outsole holds its grip and keeps you moving quickly.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"On","offers":[{"title":"White\/Black \/ M8\/W9.5","offer_id":53335856709845,"sku":"3UE30010462","price":329.95,"currency_code":"USD","in_stock":false},{"title":"White\/Black \/ M8.5\/W10","offer_id":53783275176149,"sku":"3UE30010462","price":329.95,"currency_code":"USD","in_stock":false},{"title":"White\/Black \/ M9\/W10.5","offer_id":53812914094293,"sku":"3UE30010462","price":329.95,"currency_code":"USD","in_stock":false},{"title":"White\/Black \/ M9.5\/W11","offer_id":53812914127061,"sku":"3UE30010462","price":329.95,"currency_code":"USD","in_stock":false},{"title":"White\/Black \/ M10\/W11.5","offer_id":53335856840917,"sku":"3UE30010462","price":329.95,"currency_code":"USD","in_stock":false},{"title":"White\/Black \/ M10.5\/W12","offer_id":53335856873685,"sku":"3UE30010462","price":329.95,"currency_code":"USD","in_stock":false},{"title":"White\/Black \/ M11\/W12.5","offer_id":53335856906453,"sku":"3UE30010462","price":329.95,"currency_code":"USD","in_stock":false},{"title":"White\/Black \/ M11.5\/W13","offer_id":53335856939221,"sku":"3UE30010462","price":329.95,"currency_code":"USD","in_stock":true},{"title":"White\/Black \/ M12\/W13.5","offer_id":53335856971989,"sku":"3UE30010462","price":329.95,"currency_code":"USD","in_stock":false},{"title":"White\/Black \/ M12.5\/W14","offer_id":53783273504981,"sku":"3UE30010462","price":329.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0314\/5200\/4483\/files\/Screenshot2026-03-02at5.59.54PM.png?v=1772496034","url":"https:\/\/commonwealthrunning.com\/products\/unisex-on-cloudboom-strike-lightspray%c2%a9","provider":"Commonwealth Running Co.
