Spring-loaded shoes: once the 1950s staple of Wile E Coyote, now a futuristic luxury from Rick Owens.
Released last year as an unconventional runner from adidas, the fashion designer and long-time Three Stripe partner has added his own twist to the German label's Springblade Razor system.
While they might look a touch unstable, each one of those angled blades on the soles of the shoe compresses under a person's weight, adding a literal "spring" to your step when running to help move your foot forward.
In the hands of Owens, the high-tech sole has been added to a low profile leather and mesh canvas upper - part breathable sneaker, part luxury trainer.
While they might help you shave a few tenths of a second off your 30-metre dash for the bus home, we doubt you'd want to risk scuffing them - at £409 a pair, these are the sort of shoes you'll want to move very carefully in. You can pick up a pair now from Hanon.
