Rob is a Nike Air Vapormax Dam perfectly proportioned, living, breathing Coors Light commercial of a man. He talks about running a marathon without really training for it and, recently, his “first” 50K. Of course he would be who Nike would send to take me–someone who hasn’t exercised Nike Air Huarache Dámské in six months, maybe a year–for a tour of their latest shoe, not some normal human being, but 180 impossible pounds of Just Do It.“Let’s run a couple of miles,” he says with the casual rapport of a lesser-known Marvel superhero.We’re at a gym in Chicago’s north side, stepping onto side-by-side treadmills to try out Nike’s latest paradigm in shoes: Nike Epic React Flyknit. I haven’t run regularly in nearly a decade. I am terrified. But dang, my feet sure do look good.Three years in the making, React is Nike’s sequel to its pillowy Lunar technology, and the Epic React Flyknit is the Nike Air Max 2017 Womens first running shoe to feature the new technology. With it, Nike is chasing one of the biggest performance-fashion trends led by Adidas’s Boost line. Like Boost, React is a shoe all about maximalism, rather than the barefoot minimalism of the past Adidas ZX 700 Femme few years. Its main feature is a giant sole Nike Air Max 2017 Dam made from a single block of foam, which promises to put a percentage of the energy from each footfall back into your next step.

The goal of React is to be the trifecta of what most people want in a running shoe: light to lift and soft on the footfall, but with the ability to bounce back with your stride, rather than bottoming out. In the industry, they call this third trait “energy return,” and it’s the hottest promise in athletic shoe technology today. The barefoot running era of the early to mid-aughts is over. Now, it’s all about big soles Adidas NMD Femme and energy return.Of course, a large sole is a necessity for foam to achieve this rebound, but it’s also an advertisement of soft springiness–just looking at the Epic React, you feel like it must give you some extra power as a runner. “We wanted Adidas Superstar Uomo it to be visually distinct, and to be intuitive when you pick up the product,” says Brett Holts, VP of Nike Running Footwear. “You see there’s something about this that looks softer, more cushioned than a slab of foam. There’s a visually intuitive part to [to this approach].” Meanwhile, the upper is a tighter weave of Nike’s Flyknit technology than its sometimes sock-like weaves, which secures your foot tightly onto the pad.Unlike most athletic shoes, there is no hard outer sole “cage” or internal air bags for the soft foam of the Epic React. Instead, the proprietary React foam–which Nike Air Presto Femme itself is mostly made of synthetic rubber, normal for car tires but a shoe industry first–is punctuated by a bit of harder rubber under your toe and heel, to maximize durability on pavement. React was the product of Nike’s own innovation lab, Nike Air Pegasus 83 Femme and the result of over 400 attempts of mixing new materials at a factory in Taiwan, shaping them and cooking them in ovens, then testing these bricks of foam before actually molding them into a shoe and trying them on.

Testing includes the simple thumb test (pressing in your thumb, seeing how far it sinks in, and then how it bounces back), but also includes hooking the material up to small machines that can measure these traits in quantifiable numbers. Again, Nike was looking to make something that could bounce like a rubber ball, but strike like a feather, a combination that, if you Adidas Superstar Donne Blu think about it, doesn’t really exist in the material world.“It’s a lot like baking. You have your bread, flour, egg, and salt. And yeast,” says Hossein Baghdadi, director of Nike NXT Footwear, and lead on React. “I can use different yeast strains, Nike Air Odyssey Womens different flours. Different salt. But also combine them in different ratios. And depending on how I bake that bread, I can end up with a nice crust, or I can burn it, or I can overcook it.”Baghdadi’s team tested new mixes and baking methods on a daily basis. They could literally come up with a new composition and be holding a foam block a few hours later. In a few more hours, that foam could be a prototype shoe on their feet. Each chemical iteration was tested with all sorts of machines and methods, but ultimately Baghdadi became extremely good at just feeling such minutia on his feet.This time around, things were to his liking. Wall signed a five-year deal with the brand which gives him a bit more flexibility than an eight-year deal would. Plus, he got a new start with a new team to build his brand up again.
