Are Nike promising a 52% reduction in running injuries

    The Nike React Infinity Run Keeps You Running

    November 06, 2019
    • [​IMG]
    Imagine a world where every runner gets faster. Pretty exciting. But also a hearty challenge, given the presumed hurdle of injury. But are injuries actually inevitable? The question spurred Nike to focus efforts on the potential of reducing runner injury, and its newest running shoe, the Nike React Infinity Run, is a step toward that objective.
    When Nike debuted the Zoom Vaporfly 4% in 2017, racers cheered; the shoe was built for notching PRs and breaking limits — privileging running economy. The same year, Nike React, a proprietary foam offering game-changing cushioning and energy return debuted. In running, the technology answered for a near impossible desire: A feel that was soft, resilient, lightweight and durable.
    The Nike React Infinity Run encompasses the best qualities of those two technologies — a fine-tuned blend of biomechanical efficiency and cushioning — for a breakthrough shoe that offers a more democratic solution to stability, and an advance from traditional motion-control designs.
    The Infinity Run provides a soft, responsive platform and delivers it with a widened midsole. Similar to the geometry of the 4%, the Infinity has a rocker-like bottom that yields a more fluid transition from foot strike to toe off.
    This inspired combination has an instant impact on a runner. Slip the shoe on, and it feels at once stable and energetic, the spring in the React foam ready to fuel miles. The Infinity’s rocker-geometry encourages a slight lean forward, moving a runner’s foot strike from heel to midfoot, or even forefoot; this creates a natural forward feel of propulsion. The wider platform, and the supportive foam that accompanies it, provides a reassuring feel — the shoe gently guides the foot in a smooth, straight line, reducing side-to-side wobbling and movement.
    These attributes make the Nike React Infinity Run ideal for the kind of runs that don’t fall into the silo of interval or tempo, long run or race. This shoe matches best to base-run days, those middle-mileage, moderate efforts. In fact, an external study by the British Columbia Sports Medicine Research Foundation (BCSMRF) on 226 runners in the Nike React Infinity Run and the Nike Structure 22, a traditional motion control shoe, showed that runners in the Nike React Infinity had a 52 percent lower injury rate than in the motion control shoe, with wearers confirming that they felt less pain in their knees and feet.
    Why Variable Training Matters

    Just as mixing up movements and intensity in training will build a fitter, more complete athlete, doing a variety of types of running workouts will increase speed, strength and endurance — while also helping to prevent the kind of overuse injuries all too common to runners. The sport’s most successful champions — we’re looking at you, Eliud —are known to incorporate a range of running workouts (and corresponding types of running shoes) to stay their fittest and healthiest. Here, a glossary of some of the most common variables and how to incorporate them into your own training.
    Long Run
    As the name suggests, these workouts are a runner’s highest mileage and usually slowest speed, and are meant to build muscle endurance (along with mental fortitude).
    Frequency: Typically once a week
    Base Run
    Mid-range in mileage and performed at a comfortable pace, these bread-and-butter efforts are the bulk of a runner’s mileages.
    Frequency: Two or three times a week
    Intervals and Fartleks
    Alternating high-intensity sprinting with a period of recovery, these short bursts build speed and stamina. Intervals are commonly performed on a track to dial in precise distances, while fartleks are often spliced into base runs.
    Frequency: Once or twice a week
    Tempo Run
    These mid-distance, faster sessions push a runner to a challenging speed — think 85 percent of maximum effort — to help build the strength and endurance to run fast for longer periods of time.
    Frequency: Once or twice a week
    Recovery Run
    Typically performed after a muscle-depleting race, time trial or hard workout, these runs are short in distance, easy in intensity and meant to give the body the opportunity to bounce back while continuing to log miles.
    Frequency: As needed
    [​IMG]
    Seasoned runners know that for optimum performance and injury prevention, it is crucial to vary the types of runs you do. The same goes for the shoes you wear. Nike’s suite of running shoes caters to the variety of workouts that help deliver peak results, and with the Infinity, that suite now has a key new staple.
    The Nike React Infinity Run will be available January 3 for Nike Members and receives a general release January 16.

    What is the study that they are basing this claim on?

    We do not know yet and its not published.
    That has not stopped a lot of armchair clowns criticizing the study, knowing nothing about it!

    How can one make claims without first publishing the data to support those claims and establishing where the claims can be freely vetted by all?

    They only just come the market and a few have tried them.
    We just did a PodChatLive episode on the shoe and the injury claims:

    The Nike React Infinity Run 2 and the Nike ZoomX Invincible Run: Keeping You Strong and Carrying On

    December 30, 2020

    A goal as ambitious as reducing running injuries can be approached in two ways. One is to refine an existing silhouette to make it even more effective. The other is to introduce a fresh solution. To that end, the Nike React Infinity Run 2 and Nike ZoomX Invincible Run continue the mission from Nike Running to crack the injury-prevention code, serving everyday runners by creating a new relationship among cushioning, stability and rocker geometry.
    The iterative step is the Nike React Infinity Run 2, which features an updated Flyknit upper to help promote more strength and support in the toe, eye-stay and foxing, and with more breathability in areas like the vamp and the midfoot (Nike Flywire cables have also been added throughout the upper to help increase support). The collar is also updated to feel more plush without adding weight or bulk.

    “Two things come to mind,” says distance runner Vanessa Fraser about the Nike React Infinity Run 2. “One, I feel secure in the shoe. Both the upper and the heel feel great and, for me, were an improvement from the first version. Second: the sole. While familiar, it's so soft yet reactive, and really responsive with a spring-like feeling.”

While familiar, it's so soft yet reactive, and really responsive with a spring-like feeling.”
    A new step altogether in the search for harmony among cushioning, stability and rocker geometry is the Nike ZoomX Invincible Run. The midsole is made with responsive ZoomX foam, which returns more energy underfoot than any other Nike foam.
    Created for long training runs, the Invincible silhouette includes more foam in the midsole than React foam in the Infinity, creating a soft ride while returning more energy for improved running economy. The rocker geometry and the wider nets in the forefoot help create a more stable ride and fluid stride transition (compared with the more springy transition of plated running footwear), making the Invincible ideal for higher mileage runs.

    “When I first put on the ZoomX Invincible, the sensation was crazy,” says middle-distance runner Donavan Brazier. “I was like, ‘Oh wow! You can really feel this.’ But I wasn’t even sure what ‘this’ was. It was just a new sensation.”
