t’s been 10 years in the making, but the (from £138,) has arrived – and it’s the company’s lightest ever CO2E emissions trainer. Part of the brand’s commitment to achieve net-zero emissions by 2050, the trainer features a new carbon-negative foam, derived partly from sugarcane, in the midsole and sockliner, plus the trainers are also made with recycled and solution-dyed polyester. The net result is the shoes emit just 1.95kg CO2E per pair. They’re also lighter than other low CO2E trainers on the market, not to mention rumoured to be super-comfy, too.
