Saucony’s breakthrough minimalist model undergoes a reboot that incorporates seamless upper construction, newly-configured outsole design, and all of the lightweight support that made the shoe a hit in its last two incarnations. The “Best Debut” winner from Runner’s World boasts a new and intuitive design while retaining all of the features that made the Kinvara 1 and 2 huge successes in the minimalist market.

At its core, the shoe’s vital stats remain the same: the Kinvara 3 hits the scales at a svelte 7.7 ounces, retaining the same weight as the past two versions. Additionally, the heel-to-toe drop remains at 4 millimeters. The profile of the shoe is essentially reminiscent of the currently-available model, differing slightly in the heel profile and the lacing design (the lowest eyelet has been removed). With the latest version of the Kinvara, Saucony strove to make minor adjustments to the metrics runners judge the most while improving the construction and feel of the shoe in its upper and outsole.

The most noticeable changes are seen straight away, as the upper now incorporates Saucony’s FlexFilm technology—a lightweight plastic-based overlay that eliminates the need for stitching. The technology comes over from the company’s lightweight racing flats, and claims to create a comfortable and secure fit. For a shoe which is already known for having a silk-soft upper, the new design feels even smoother and more comfortable than its predecessors. Saucony boasts on its website that “sockless runners will be happy with the Kinvara 3,” and we’re inclined to agree.

Outside of the redesigned upper, the Kinvara 3 features revamped outsole which incorporates the no-nonsense construction of the 2 and 3 with minor adjustments in the heel and midfoot. The heel design has transitioned into a decoupled and beveled design, aiming to assist runners have a smooth transition on landing and push-off. Additionally, the outsole features reinforced rubber lugs in the shoes’ most-common wear spots. Located on the lateral and media edges of the outsole, the Kinvara 3’s outsole has XT-900 foam which helps support midfoot running. Having reinforced rubber in these trouble spots will be a welcome change for Kinvara enthusiasts, and newcoming midfoot runners as well.

All in all, our first look at the Kinvara 3 is incredibly promised. As we come close to the early May release of the model, stay tuned to RunningShoesGuru for a full review.
