Unisex On Running Cloudboom Strike LS

Marathon shoe reimagined. On Running's limited edition Cloudboom Strike LightSpray racing shoe, is On’s lightest, fastest and most innovative yet!

It features a LightSpray upper for a seamless, laceless and distraction-free fit. By minimizing waste and emitting 75% less CO₂ than other premium uppers, the production process is more environmentally friendly. The upper is produced by robot using a single 1.5km long filament, making it breathable and elastic without the need for laces. And at just 30g, it is the lightest upper On has ever created.

The midsole boasts of Helion™ HF hyper foam combined with a pre-shaped, sturdy carbon fiber Speedboard® for powerful propulsion. Expect the smooth, bouncy and responsive feel, without overly aggressive or rigid propulsion.
