The Nike Vaporfly 4 Proto is a lean, mean, mile-eating machine. We trimmed weight in the midsole, outsole and upper from the Vaporfly 3 without sacrificing performance. The result is a lighter, more propulsive all-around racing shoe that\u2019s trusted from the mile to the marathon.<\/p>\n
The handwritten number on the midsole salutes the wear-testers who put these shoes through our rigorous test process to give you the best performance possible.<\/p>\n
A full-length carbon fiber Flyplate provides a propulsive, racing feel. A higher angle of the plate and lower heel-to-toe drop compared to the Vaporfly 3 give you an improved propulsive feel.<\/p>\n
Nike ZoomX, our most responsive foam, just got faster. Running from heel to toe, it unlocks even more energy return than before thanks to a slight midsole reduction, giving you a bouncy, feathery feel.<\/p>\n
Engineered mesh offers improved comfort and a disappearing feel on your foot. It helps reduce the weight of the shoe while supplying a more consistent fit. And we reduced the size of the heel and tongue, saving even more weight.<\/p>\n
See how the midsole bulges out by the heel? We designed it that way to help reduce weight on the inside of the foot to give you a more stable ride. We reduced the weight of the outsole by using a thinner rubber compared to the Vaporfly 3. You still get the same reliability, just without any unnecessary thickness.<\/p>\n
We took a race-car approach when updating the Vaporfly 4, making many minor tweaks so you can pursue major gains. We trimmed weight in the midsole, outsole and upper without sacrificing performance.<\/p>\n<\/div>\n
