Nike reveal Air Zoom Alphafly Next%, which will be legal for Tokyo 2020

Here’s what we know so far.


Last week saw World Athletics announce major changes in regards to its rules on footwear. The new rules state that after 30 April, runners will not be allowed to compete in prototype shoes and all shoes with more than one carbon fibre plate, or a sole thicker than 40mm are banned.

Following Kipchoge’s sub-2 hour marathon in Vienna wearing the Nike Alphafly prototype, the shoe has been the subject of speculation, with many runners questioning what the new rules mean for the brand.

Today, at their Olympic Summit in New York, Nike have announced the launch of the Nike Air Zoom Alphafly Next% – a shoe with a full length carbon fibre plate and zoom air pods. We don’t have an official stack height from Nike, but Nike have told Runner’s World, “We are pleased the Nike Zoom Vaporfly series and Nike Zoom Alphafly NEXT% remain legal. We will continue our dialogue with World Athletics and the industry on standards for performance footwear that meets the needs of elite and everyday athletes.”
