      CleanCloud® explained

      We combined various technologies to capture CO2 before it enters the atmosphere to create EVA (short for Ethylene Vinyl Acetate). A high performance foam we call CleanCloud®.

      “We wanted to see if we could take a resource that is abundant in the atmosphere and do something positive with it” - Jean-Philippe Romain, Science & Innovation Director

      An innovative solution to the fossil-based midsole materials used in traditional sports shoes, CleanCloud® is the first EVA midsole made using captured carbon emission and is indistinguishable in feel, comfort and support. Our first step in introducing carbon capture to premium performance.

      Our partners at Infinium use renewable power, water and captured CO2 to create eNaphtha – a cleaner alternative to processed crude oil.

      Wavy lines of liquid are shown within a white circle on a blue background.

      Our partners at Borouge International then restructure the eNaphtha at a molecular level, splitting its elements into building blocks such as Ethylene, which is converted into EVA, needed to engineer our gear.

      We then blend EVA with traditional materials and additives to create a light, responsive and high-performance EVA foam.

      This is molded directly into our CloudTec® midsoles. So you get the same sensation, while we reduce our reliance on fossil fuels.

      It all started in 2019 with a dream. A belief we could defy the industry. And a crazy idea.

      Good Chemistry

      We partnered with visionary companies across biochemicals, material innovation and production processes to take CleanCloud® EVA from a bold idea to something that moves us, and the world, forward.

      Moving from lab to scale. CleanCloud® meets Cloud X 5

      If we’re going to dream, we’re going to dream big. If we’re going to lower our carbon impact, we’ll start with our most popular shoe.

      The Cloud X 5 is On’s first major style to integrate CleanCloud® foam into the midsole. Flexible, lightweight, built to move with you. Pairing carbon capture with uncompromised performance.

      Sustainability at On

      We’re on a mission to create high-performance products that leave less behind. CleanCloud® is our first step in bringing commercial carbon-capture footwear to the global market. But we’re only just picking up the pace.
