Our testers are fans of the increasingly common rocker shape built into running shoes, and the Infinity Run capitalizes on its performance benefits. The rocker encourages a slight forward lean, Nike says, to move a runner’s natural footstrike to the midfoot or forefoot, which creates a natural feeling of propulsion. Nike carved the midsole into a rocker shape, similar to the curve of the midsole and carbon-fiber plate in the original Nike Vaporfly 4% marathon shoe. The React foam midsole lends the Infinity Run an energetic ride, but the shoe’s shape also plays a major role in its performance. But none of our testers felt the need to adjust the laces. Nike only included four eyelets up the center of the shoe, which limits the ways runners can customize the lacing. Two testers felt a small amount of heel slippage when they were first walking around in the shoe, but both say it didn’t cause any problems when they started to run.Ī generous pull tab makes slipping into the shoe a breeze, and the straightforward-albeit minimal-lacing system adds an extra layer of security to the fit. Nike instead finished the collar with contrasting stitching. There’s no extra padding in the ankle collar, either. Nike wrapped an extra overlay around the back of the shoe to give the lightweight upper extra structure in the midfoot, and they incorporated a thin heel counter to help secure your foot. “Some shoes are too narrow for my forefoot, but the Infinity Run has enough room and enough stretch to work really well for me.”

“Everything about the shoe fits my feet well,” says a wider-footed tester. The elastic tongue not only maintains the shoe’s one-piece construction and clean silhouette, but the stretchiness also helps accommodate higher-volume feet. The Flyknit is slightly stretchy in the forefoot, and it’s dotted with micro perforations to help it breathe easily.īut it’s the integrated tongue that really shines, giving the shoe a sock-like feel.įorgoing a traditional shoe tongue, Nike seamlessly knit a swatch of soft, stretchy fabric in its place. It’s still React foam, though, so you can count on it to cushion every step and spring back into shape.ĭesigners wove a single-layer Flyknit upper to give the shoe a sleek look and streamlined fit. The Infinity Run stack height measures 30.5 mm in the heel and 21.5 mm in the forefoot, and it employs and extra-wide base to mitigate any side-to-side wobbling. But it’s not just taller-it’s wider, too.Ĭompared to the Fleet Feet review of the Nike Epic React Flyknit 2, testers felt the difference in midsole cushioning. Nike says it packed the shoe with 24 percent more React foam than the popular Nike Epic React Flyknit 2.

The big news on the Infinity Run is the midsole. Our testers think the new Nike React Infinity Run nails both. To be useful for long miles and big training cycles, an everyday running shoe has to fit comfortably and be durable.
