(Telegraph) Adidas, the sportswear giant, wants to turn trainers into one of life’s luxuries you’re prepared to pay for in ounces. Well, it’s one specific pair of trainers: the AdiZero Crazy Light. Designed for basketball players, the shoe weighs in at 9.8 ounces and will sell for $130 (£80). Or, when you’re next in a shoe shop, at just over £8 an ounce. The Germany company claims the shoe, which will go in sale in June, is 7.5pc lighter than the nearest offering from arch rival Nike, named after Kobe Bryant, one of the game’s biggest stars.
