VaporWeave is used on the VaporFly Next% and the Zoom Fly 3. VaporWeave is very breathable but doesn’t conform to the foot so creasing may occur. Its main advantage is that it doesn’t absorb water so during a race, the shoe will not absorb sweat and weigh you down. VaporWeave is an engineered, woven mesh with a smooth, plastic-like feel which is light and strong. AtomKnit is extremely lightweight, very breathable and does not absorb water.ĪtomKnit is only used on the flagship shoe, the AlphaFly Next%. The difference between AtomKnit and FlyKnit is that AtomKnit is steamed and stretched. It has a smooth, plastic-like feel and does not stretch.įlyKnit Loft is used on the Infinity Run.ĪtomKnit is a new, more advanced type of FlyKnit material. It has 3 distinct layers which help keep the foot secure. FlyKnit LoftįlyKnit Loft is a FlyKnit variation which is breathable and durable. Most notable examples of Flyknit shoes are the Flyknit Racer (as the name implies, a fast and light shoe for racing distances all the way to the marathon) and the Nike Free Flyknit (an extremely flexible and lightweight running shoe to strengthen and train the muscles in your feet). This technology is Nike’s latest, so expect to pay a premium for Flyknit shoes. Flyknit also allows for extremely precise upper fit, being able to seamlessly integrate tight-knit areas where support is needed and wide-knit areas to allow for flexibility.įlyknit is environmentally friendly as it produces 60% less waste than traditionally constructed running shoe uppers.
Upper technologies Flyknitįlyknit is a special woven fabric that makes the upper of a shoe feel like a sock, by placing yarns and knits strategically around the structure in order to support the foot of the runner when needed and leave it free everywhere else.įlyknit running shoes are lightweight: a light yarn replaces multiple stitched or glued panels. Understanding the meaning and design principles behind the tech names will help you navigate through the catalog faster. Not sure that is a drawback to the shoe – I use a different shoe for running trails or more aggressive terrain.An explanation of Nike running shoes technologies With the lightweight of these shoes, you are kind of restricted to a smooth surface.At 140 miles there are no signs of failure Great price point – at around $70, the Run Swift is a bargain running shoe.Flywire construction on the sides provide extra support for the mid-foot.I use Sofsole inserts in my running shoes – makes all the difference for me. The only modification to my shoes is an aftermarket insert. Specifications have the shoe at 9.5oz, but I weighed mine and they came in at just over 8oz each. Other shoes with a heavier construction and/or materials will fatigue me much quicker than these Nike Run Swift. So, lightweight is an advantage in my book. I suffer from lower leg fatigue when I run and the longer the run the more I feel my shoes on my feet. Two things about the shoe that I think really set it apart from other shoes I have worn – Lightweight and breathable construction. I have about 140 miles on the current pair of Run Swift, and as mentioned above, used pretty much on just pavement.
And, let’s face it, Nike has really increased its stake in the running shoe market with a lot of serious research and development. I used Nike a few times in the past but we are talking several years ago, and my running commitment was less than serious. I have tried many, many running shoes over the years only to be disappointed either in the price or comfort at the end of the day. My pronation is neutral and regular width. My use of the Nike Run Swift is pretty much exclusively road with an occasional gravel road or grass path. My running experience is amateur, only in the sense that I am not a competitive runner, with an average per week miles of 10 to 15. The Run Swift is my favorite running shoe for the road, track, and light terrain conditions. A great shoe by Nike for a very affordable price.
