The stability shoe that replaced Newton’s Isaac model is a huge hit among our wear-testers.
When Newton Running launched in 2007, it shocked the running world with a unique design that included external forefoot lugs designed to maximize energy return and forefoot propulsion. The “Action/Reaction Technology” has served the brand well and helped it gain a big following among triathletes, fast runners and those interested in improving their running gait.
This summer, Newton released two next-generation shoes that still offer the game-changing technology but also appeal to a wider range of runners. Like the neutral-oriented Fate, the Kismet, a light stability model, is an everyday trainer that has a slightly more spacious interior and wider outsole footprint—features geared toward offering a smoother, more comfortable and more stable ride to a wider range of runners. The Kismet is the shoe that replaced the Sir Isaac/Lady Isaac models and our wear-testers found it to be not only lighter and more agile, but considerably better overall than its predecessor.
The most enticing feature is Newton’s new, slightly wider five-lug forefoot propulsion unit. It works similarly to Newton’s original Action/Reaction Technology units—the lugs channel forefoot impact energy through a responsive elastic layer and into a hollow chamber in the forefoot. But the lugs in the Kismet (and the Fate) are beveled and not quite as high off the ground as previous versions, both of which lead to a smoother transition into the toe-off phase of the gait cycle. You barely notice the lugs, but you definitely feel the pop they provide.
Aside from a little more support built into the undercarriage of the shoe, the Kismet is very similar to the Fate. (And that makes sense, since the shoes have names that mean the same thing.) It’s a moderately soft, fairly light and very energetic trainer that’s ideal for high-mileage training volume but also versatile enough for tempo runs, fartlek workouts and variable-speed progression runs. It has a medium-volume interior and medium fit in the heel and midfoot but plenty of wiggle room in the toe box.
