Nike Zoom Fly 6 JI Running Shoes
Jakob Ingebrigtsen's subtly brilliant Zoom Fly 6 is synonymous with his style and focuses on what matters most: family and finishing first. Lighter than the Zoom Fly 5, its responsive ZoomX foam adds energy return to each stride, while a carbon fibre plate helps propel him to the finish line.
Engineered Mesh Upper
The upper has been constructed from an ultra-breathable mesh to ensure total comfort. Durable yet airy, the upper features micro-perforations throughout to allow built-up heat and vapour to escape whilst encouraging fresh air to flow in for a pleasant cooling sensation. Lighter than the Zoom Fly 5, this upper is ultra-lightweight with a minimalist tongue to shave down the weight for maximal speed. Synthetic leather on the upper adds durability in key areas, a traditional lacing system allows you to lock in the fit for confident, controlled strides. Reflective details ensure visibility in low light, meaning you can keep running beyond dusk till dawn.
ZoomX Foam Midsole
The midsole of the Zoom Fly is crafted from ultra-responsive ZoomX foam. 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 superfluous muscle power, diminishes fatigue and enhances performance, keeping you going longer. The revolutionary ZoomX foam is manufactured from Pebax, a product conventionally used in plastic bridges and other moulded parts and yields lightweight, soft and springy cushioning. Until now, these three characteristics (collectively) have proven nearly impossible to achieve. Pebax has a lower density than some thermoplastic alternatives, making 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 a lively underfoot feeling that encourages you to run fast. Signalling the incredible resilience of ZoomX, the tiny creases on every midsole do not impact the foam's performance; these beauty marks are results 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 can 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. Reinforcing this bouncy, energetic feel is a full-length carbon fibre plate that provides snappy energy return for greater efficiency, giving you that flying feeling. The midsole also features a rockered construction, utilising the power of your last step to push you into your next one so you run further faster with less effort.
Thin Durable Rubber Outsole
The Zoom Fly 6 features a thin yet ultra-durable rubber outsole to reduce weight without reducing longevity. The rubber forms a solid bond with the ground underneath for great adhesion and grip, meaning you can focus on the run without worrying about slipping. The rubber provides traction on variable road surfaces easily, allowing you to propel forward and change direction easily and confidently.
