The React Infinity Run Keeps You Running
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 its efforts on reducing runner injury; hence, 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. In 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 or Infinity encompasses the best qualities of these two technologies for a breakthrough shoe that offers a more democratic solution to stability and motion-control designs. It provides a soft, responsive platform, and delivers it with a widened midsole similar to the geometry of the 4%. Likewise, it has a rocker-like bottom that yields a more fluid transition from foot strike to toe off.
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 propulsion. The wider platform and the supportive foam that accompanies it provide a reassuring feel. The shoe guides the foot in a smooth, straight line and reduces side-to-side wobbling and movement.
This shoe matches best to base-run days even those middle-mileage, moderate efforts. In fact, an external study by the British Columbia Sports Medicine Research Foundation on 226 runners using the Infinity and traditional motion control shoe Nike Structure 22 showed that runners wearing the Infinity had a 52% lower injury rate confirming that they felt less pain in their knees and feet than those who used the motion control shoe.
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 Eliud—are known to incorporate a range of running workouts (and corresponding types of running shoes) to stay their fittest and healthiest. Below, a glossary of some of the most common variables and how to incorporate them in your training.
As the name suggests, these workouts are a runner’s highest mileage and usually slowest speed, and are meant to build muscle endurance alongside mental fortitude.
Frequency: Typically once a week
Mid-range in mileage and performed at a comfortable pace, these bread-and-butter efforts are the bulk of a runner’s mileage.
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
These mid-distance, faster sessions push a runner to a challenging speed— think 85% of maximum effort—to help build the strength and endurance to run fast for longer periods of time.
Frequency: Once or twice a week
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
Seasoned runners know that for optimum performance and injury prevention it is crucial to vary the types of runs they do. (Please See Why Variable Training Matters) The same goes for the shoes one wears. Nike’s suite of running shoes caters to the variety of workouts that help deliver peak results.
The Nike React Infinity Run will be exclusively available on January 23 for Nike Members at Nike Park Mall of Asia opening. Its retail launch is set on January 30. Visit Nike React Infinity Run for more details.
