On Cloudboom Max: The super shoe made for every marathon runner

Not everyone is chasing a sub 3 marathon, but everyone wants a race-day shoe that makes running feel easier. The On Cloudboom Max is designed for runners aiming at around a 4:00 to 4:30 finish. From the streets of Cape Town to the climbs of Joburg, this shoe helps you move smoother and finish stronger.

Key features & benefits

  • Helion HF foam midsole: Cushions every step without feeling heavy. It delivers a soft but energetic ride through long miles.
  • Dual-layer construction: Two layers of Helion HF foam add stability and extra comfort for the marathon distance.
  • Glass-fibre Speedboard: Provides snappy propulsion and helps your stride roll forward efficiently.
  • CloudTec cushioning: Signature pods soften landings while guiding each stride into a smooth transition.
  • High stack geometry: At about 40 mm in the heel, the Cloudboom Max provides plenty of cushion while staying race focused.
  • Breathable mesh upper: Light and airy, keeping feet cool and supported for the long haul.

Why it works in South Africa

The Cloudboom Max from On running offers the balance most marathoners need. It is cushioned enough for Comrades training, yet efficient enough for a road marathon. Whether you are on the flat stretches of Durban or the rolling tar of Gauteng, the rocker-like flow helps you maintain rhythm and save energy.

Pricing & value

At around R4,999, the Cloudboom Max competes with other super shoes like the Nike Vaporfly and adidas Adios Pro. The difference is that it feels a little more forgiving, which makes it a better fit for a wider range of runners.
