Nike Zoomx Vaporfly Next% 2 "Total Orange" Sneakers

The second generation Vaporfly is the one that ran straight through the sport's biggest rules argument. Nike launched the line in 2017, pairing ZoomX, its altered Pebax foam, with a full length carbon fibre plate built to add spring to every stride, and peer research found the combination could improve marathon times by up to 4.2 percent. On 31 January 2020 World Athletics responded with shoe regulations capping sole thickness at 40mm, allowing a single rigid plate and requiring four months of general retail availability. Compliant Vaporfly models remained legal. Total Orange is the shoe wearing the loudest colour in the range, which suits a product that spent its life being looked at.
