Highlights

  • CloudTec cushioning with Helion HF Cloudboom Volt leans into speed with a full CloudTec cushioning platform paired with dual layers of Helion HF hyper foam, tuned specifically for race-day turnover. The foam setup balances firmness and energy, giving you a crisp, snappy toe-off instead of a mushy sink. It is built to stay responsive at faster paces, keeping your stride feeling spring-loaded, even when your hamstrings file a complaint.
  • Carbon-infused Speedboard propulsion Underfoot, a full-length carbon-infused Speedboard runs through the midsole, acting like a tensioned spring that wants to snap back to straight every time you load it. That means more forward roll with less effort from your calves. It is slightly less explosive than On’s premium marathon plates, but more approachable, making race-shoe tech feel less like a spaceship and more like your new daily superpower.
  • Aggressive rocker for race distances The midsole geometry is all about forward momentum: an aggressive forefoot rocker and moderate heel bevel help you transition from landing to toe-off in a fast, rolling motion. Paired with a relatively narrow, neutral platform, it favors runners who like to stay up on their toes and attack tempo. Think 5K, 10K, half-marathon efforts, with just enough structure to stretch to a marathon if you are stubbornly ambitious.
