![]() ![]() 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. ![]() I think if you need a simple daily trainer or a value pair of sneakers for around town, the Run Swift 2 is worth a look.An explanation of Nike running shoes technologies It’s more comfortable, and a bit more high-end feeling than say the Quest 4 or the Downshifter 11, and I like the classic, refined style better as well. Once again, like many other Nike budget shoes, there are no reflective elements on the Run Swift 2, meaning you need to be extra careful should you be out running after dark.Īt $70 I think there’s actually good value in this shoe. The upper is plenty breathable with its wide-mesh construction and even though it has a thick 9.0mm padded tongue, the shoe didn’t feel hot on my feet. This shoe is comfortable on pavement and mild dirt running paths, which is a nice element for a do-it-all style of shoe like this. The outsole also features 2.2mm lugs giving it extra grip on varied terrain. The full-rubber outsole is generously thick at 4.4mm (average outsoles are just 3.5mm), and the rubber is firm at 88.5HC on the durometer (compared to an average of 80.5HC), meaning the shoe should wear slowly and have plenty of life. The shoe seems well built with plenty of welded overlays on the upper to keep debris out and act as an added layer of protection against abrasion. The Run Swift 2 isn’t all that swift… At 10.3 ounces (291g) it’s more of a clunker than a light and nimble shoe built for speed.Īgain, I see this as more of a performance sneaker than a true running shoe because of the weight here. The flex was affected just 3% compared to the average shoe being 35.3% stiffer at cold temps. I actually think they look sweet and feel good enough to wear walking around in.Īnother positive is this shoe didn’t seem to stiffen up much in our freezer tests. Honestly, for me, it’s a bit dull and I wouldn’t want to run these for anything longer than a recreational jog, but where I so dig them is just as a town sneaker.
