React doesn’t have sink-in softness but has a dense, rubbery feel with a noticeable spring.
It is lightweight, durable and resistant to temperature changes. React is a styrene-based material which is a synthetic rubber. Each company has their own trademark foam mix that tries to achieve the following: be as lightweight as possible, be soft in order to absorb the impact with the ground, be elastic (in order to compress on impact and release propelling you forward), be durable (foam does deteriorate with use, so all foam materials need to be engineered to maintain its characteristics for a decent amount of time). Midsoles of running shoes are made of foam. An overview of Nike running shoe sole and cushioning technologies It is a completely different construction than the previously mentioned Flyknit and shoes with Engineered Mesh usually have a lower price-point.Įngineered mesh is used on the Pegasus 37, Miler, Vomero 14, Downshifter 10 and Winflo 6. Engineered Mesh or FlymeshĮngineered Mesh (sometimes called “Flymesh” by Nike) is a lightweight mesh construction that is – compared to traditional mesh fabrics – more breathable and is at the same time both more durable and flexible.Įngineered Mesh features more prominent perforations than traditional mesh. 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 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.
