On's marathon shoe. A double layer of Helion HF hyper foam sits under a glass-fibre-infused Speedboard, so the stack is deep enough to carry you through the late miles and still returns something at every push-off.

Above it the build is deliberately spare - a light, breathable mesh upper that moulds to the foot, with padding kept where a long race needs it, around the heel. It is built for the distance rather than for the first mile.

Features
  • CloudTec cushioning system engineered for fast runs
  • Double layer of Helion HF hyper foam for energy return
  • Glass fibre-infused Speedboard for efficiency and support
  • Lightweight, breathable mesh upper
  • Supportive upper moulds and adjusts to the foot's movements
  • Padded heel design for comfort over long distances
  • On's own road running style rating: Fast
  • Built for running and road racing
Materials & Care
  • Upper: Lightweight breathable mesh that moulds to the foot, with a padded heel
  • Midsole: Double Helion HF hyper foam with a glass fibre-infused Speedboard
  • Outsole: Rubber, placed for road racing wear
  • Care: Remove the laces, hand wash with a mild detergent and air dry away from direct heat
Size & Fit
  • Take your usual running size.
  • Stocked in one fitting: Regular.
  • The mesh upper moulds and adjusts as the foot swells over a long race.
  • Do not size up for marathon foot swell - heel slip over 26 miles causes more trouble.
