Nike will launch the Swooshfly in China in February 2027, followed by a global spring release through nike.com and select retailers. The new race-day platform pairs SkyX supercritical foam, a carbon fibre Flyplate and a dual-rubber outsole for runners new to race-day footwear. It delivers up to 16 per cent more energy return than the Nike Vaporfly 4 in a men's size 10.
