Zurich-based firm, On, which invented the Cloudboom Strike LS running shoe, says its most important gauge of success or failure is whether the athletes wearing their shoes win.

Composed of a carbon fibre sole without a heel cap or toe spring, the Cloudboom's surface is made of a thermoplastic that sets and binds in just three minutes.
Marc Maurer, On's CEO, announced that the material, which is dubbed LightSpray, has "the potential to move us towards a more sustainable future".
