COMFORT THAT NEVER ENDS
From big races to everyday practice, the Nike Epic React Flyknit 1 delivers crazy comfort that lasts as long as you can run. Its Nike React foam cushioning is springy but lightweight, durable but soft, for an “Instant Go” feel that helps make running more fun.
Nike React foam is incredibly springy, with 13% more bounce than Nike Lunarlon. The more energy you put into your step, the more energy you get in return.
Feels Like the First Run
Whether you’re running on the track or in your neighborhood, Nike React foam is designed to keep its shape and feel, run after run. In our tests, champion runners like Galen Rupp said the shoe's cushioning still felt “like new” after 300 miles.
Give Your Feet a Hug
Nike Flyknit hugs your foot, for a snug, seamless feel from heel to toe, incredible breathability and an unmistakable look.
Nike Flyknit technology was inspired by feedback from runners seeking a shoe with the snug (and virtually unnoticed) fit of a sock. Nike embarked on a four-year mission with teams of programmers, engineers and designers to create the technology needed to make the knit upper with static properties for structure and durability. Then the precise placement of support, flexibility and breathability—all in one layer—was refined. The result is a featherweight, formfitting and virtually seamless upper. This unprecedented precision maximizes performance while reducing the material waste of traditional cut and sew by an average of 60%. The equivalent of six recycled plastic bottles are used in every pair of Flyknit shoes, saving millions of pounds of material from reaching landfills.
Nike Epic React Frequently Asked Questions
What are the main performance benefits of this shoe?
The Nike Epic React Flyknit combines Nike React foam midsole with a Nike Flyknit upper to deliver a lightweight, soft yet responsive ride mile after mile. Nike React foam gives 13% greater energy return than Nike Lunar foam, while still delivering a soft and snappy ride. As a direct comparison to the Nike LunarEpic Flyknit 2, the Nike Epic React Flyknit is 5% lighter, 11% softer and provides 10% more energy return.
What is Nike React?
Nike React foam was developed in-house and the unique composition gives runners foam that is lighter, softer, more responsive and even more durable than Nike Lunar foam. Historically, these four elements have been solved for individually and it was difficult to deliver them in one package. However, Nike React technology delivers them in one.
How durable is this shoe?
Nike React was built to last for many miles. Nike React technology is a proprietary foam that is more responsive and more durable than Nike Lunar foam. We know from our testing that the more foam and less rubber protection on the outsole of the shoe, the better the experience of React. So, we purposely went as minimal as possible with rubber coverage. We did see and experience in our testing some wear and tear on the outsole foam, but we believe the benefit of the minimal outsole coverage outweighs the visible wear of the foam. And our testers said although it may wear visibly, there is no perceived degradation to the running experience.
Does Nike Epic React fit to size?
Flyknit material conforms to the shape of your foot, creating a snug, hug-like feel that fits true to size. If you prefer a slightly looser fit, we recommend ordering a ½ size up
Is Nike React made from EVA?
No. The primary ingredient in Nike React foam is a synthetic rubber. The foam is proprietary to Nike – you won’t find it anywhere else.
How long was the development process?
It took over 400 different combinations of chemistry and processing to land the unique composition of the Nike React foam midsole. In addition, we have undertaken 17,000 miles of testing with some of our elite runners and also everyday runners.
Was testing only undertaken in the US or was it undertaken in other countries as well?
Testing was undertaken globally – not just in the US. It is important to test in all conditions and surfaces to ensure it delivers the best performance for the runner.
Which athletes have been involved in the development process?
We have undertaken 17,000 miles of testing with some of our elite runners and also everyday runners. Some of the elite runners include Eliud Kipchoge, Galen Rupp, Evan Jager, Emily Infield and Colleen Quigley.
What’s the difference between Nike React and Nike ZoomX?
Nike React technology and Nike ZoomX midsole cushioning are both light, soft and responsive. Specifically designed for speed, Nike ZoomX delivers our greatest energy return in our fastest line of Running footwear. Nike React foam offers a combination of four key benefits – softness, responsiveness, lightness and long-lasting durability in one single offering.
