Nike ZoomX Vaporfly Next% 3 Women's Running Shoes Catch 'em if you can. The Nike ZoomX Vaporfly Next% 3 is made for the chasers, the racers, the elevated pacers who can't turn down the thrill of the pursuit. The leader of the super shoe pack is back, but even lighter, stabler and somehow more responsive than ever. The upper is reworked and the engine underneath is tuned and ready for those who see speed as a gateway to more miles and more seemingly uncatchable highs. Flyknit Upper The Nike ZoomX Vaporfly Next% 3 features a redesigned upper made with a Flyknit fabric. This fabric is strategically placed in areas that require greater breathability, allowing heat, vapour and moisture to escape. Simultaneously, fresh air is encouraged to flow into the shoe and circulate, for a pleasant cooling sensation that guarantees cool, comfortable feet. This soft upper contours to the shape of your foot for ultimate comfort, thanks to a wider toe area giving you a roomier fit which allows for more room for natural toe flex. The shoe locks onto the foot via a traditional lacing system, anchoring them on securely for greater stability and control while the laces feature a warped design to help them remain tied. The laces loop through lightweight side supports that eliminate the need for an arch band, which helps reduce weight, meaning you won't have weight or bulk holding you back. Light padding on the tongue helps reduce lace pressure at the top of your foot and reinforcement along the forefoot makes it extra durable and secure. ZoomX Midsole Nike ZoomX foam delivers Nike Running's greatest energy return yet, and Next% adds more ZoomX for responsive comfort on race day. Ultra-light and super-responsive, the midsole material delivers Nike's greatest energy return yet; it absorbs impact and then expels it back out for a bounce-like effect. This energy-return technology reduces the use of superfluous muscle power, diminishing fatigue and enhancing performance, keeping you going for longer. The revolutionary ZoomX foam is manufactured from Pebax, a product conventionally used in plastic bridges and other moulded parts, and yields cushioning that is not only lightweight but soft and springy. Until now, these three characteristics (collectively) have proven nearly impossible to achieve. Pebax has a lower density than some thermoplastic alternatives and this makes it lighter, flexible and more impact-resistant, whilst giving it a higher capacity for energy return. When blown into a foam these properties remain, gifting you with a lively underfoot feeling that encourages you to run fast. Signalling the incredible resilience of ZoomX, the tiny creases that occur on every midsole do not have an impact on the foam's performance; these beauty marks are a result of the autoclave process which places the foam under extreme heat and pressure. The ZoomX sheets are then compressed in a Phylon preform which shapes the midsole parts. Because the special foam is so lightweight (one-third the weight of Cushlon), Nike is able to use more of it to separate your foot from the road; this means you get a thick and supportive midsole that will spare your joints as you strike down onto hard, unforgiving concrete. A newly redesigned, aerodynamic heel is designed to delay air separation and reduce drag, tapering to banish every barrier between you and your top speed. Embedded within the generous ZoomX platform, and complimenting its responsive nature, is a full-length carbon fibre plate. Intended to minimise energy loss during toe bend without increasing demand on the calf, it springs up under your heel as you stride forward, yielding the snappy, propulsive sensation that converts into extra-energised strides. The plate is curved at the front, helping give the runner back some of the energy they put in at toe-off. It's this fusion of two contrasting technologies (the ZoomX foam and the carbon plate) that results in the dynamic, power-i
