A Major Boost in Energy Return! Putting the "Nike Pegasus Plus 2" to the Test

First debuting in 1983 as a shoe built for every runner, Nike's "Pegasus" remains one of the brand's signature best-sellers, beloved by runners worldwide.

Currently, Nike's road running lineup is built on three core pillars: maximum cushioning with the "Vomero," responsive cushioning with the "Pegasus," and supportive cushioning with the "Structure." Within each pillar, alongside the iconic base models, Nike offers "Plus" and "Premium" iterations.

The latest model to get an upgrade is the "Nike Pegasus Plus (NIKE PEGASUS PLUS)." This marks its first update in about two years since the original debuted in 2024. How has this shoe evolved?

A Major Upgrade Following the Iconic Model

Built around the concept of responsive cushioning, the "Pegasus" series places equal emphasis on plush cushioning and energy return. The lineup consists of three models: "Pegasus," "Pegasus Plus," and "Pegasus Premium." The flagship iconic model received its first update in about two years this past February.

The "Nike Pegasus 42 (NIKE PEGASUS 42)" introduced a new shoe last, resulting in a slightly wider fit, especially in the forefoot. Additionally, a rocker curve was added to the toe area, creating a design that delivers a noticeable sense of propulsion. It also features a full-length, curved Air Zoom unit, successfully boosting energy return by approximately 15% compared to the previous version (based on Nike test results).

Following this major overhaul of the iconic base model, the "Pegasus Plus" has now received a massive update of its own—one that could easily be called a complete redesign.

"If you love the Pegasus 42 but find yourself wanting a bit more bounce, a lighter weight, or extra cushioning, the Pegasus Plus 2 is built specifically for you," explains Ryo Ota, an EKIN (Nike product specialist who shares technology, innovation, and development background stories).

Air Zoom Unit Equipped in the Forefoot

The "Pegasus Plus 2" offers higher cushioning and energy return than the "Pegasus 42" while remaining even lighter. Above all, the developers aimed for racing shoe-like propulsion.

"Development focused on how to create a shoe that generates speed without compromising the comfort that is core to road running shoes. What contributes most to generating extra bounce without sacrificing comfort is the Air Zoom unit—featured in the Pegasus Plus series for the very first time."

The Air Zoom unit boasts the highest energy return among Nike's cushioning technologies. Tightly stretched, highly elastic fibers are enclosed within a pressurized airbag. When your foot hits the ground, these fibers compress to absorb impact, then instantly spring back to their original shape to generate energy return.

"A key highlight is that the forefoot Air Zoom unit features a visible design rather than being completely encased in foam. Models like the Pegasus Premium and Vomero Premium also feature Air Zoom units with visible designs that maximize exposed surface area rather than being fully encapsulated.

Visible Air Zoom units can compress more dynamically than encapsulated ones, generating even greater energy return."

The Air Zoom unit in the "Pegasus Plus 2" is thicker than the one embedded in the "Pegasus 42." Like those in the "Pegasus 42" and "Pegasus Premium," it features a curved shape that supports smooth weight transitions.

Energy Return Improved by Approx. 18% Compared to Previous Model

The midsole features lightweight, highly responsive ZoomX foam, with a stack height (sole thickness) of 38mm at the heel and 28mm at the forefoot—making it 3mm thicker than the previous model.

 Combining this ZoomX foam with the Air Zoom unit in the forefoot succeeds in delivering significant energy return. Performance has reportedly improved by about 18% compared to its predecessor.

 Just like the "Pegasus 42," the size and internal pressure of the Air Zoom unit are optimized based on shoe size. This ensures that every runner can experience a similar ride.

Easy to Pick Up Speed while Staying Comfortable

The shoe uses the MR-10 2.0 last, which was first introduced in the "Pegasus 42" (providing extra room in the forefoot and toe box while keeping the midfoot securely locked in place for exceptional comfort and mobility). Generous padding around the ankle delivers a step-in feel very similar to the "Pegasus 42."

 

The upper uses lightweight single mesh. A fit band integrated into the midfoot keeps the foot securely held without slipping, even at higher speeds. The shoe weighs approximately 270g for a men's size 28cm—about 10% lighter than the "Pegasus 42."

 When walking or jogging at a relaxed pace, the plushness and high cushioning of the ZoomX foam are most noticeable. However, as you pick up the pace, its responsiveness truly shines.

It feels like a "Pegasus 42" designed to make gaining speed effortless, making it an ideal race-day option even for runners who usually rely on the "Pegasus 42" for regular daily jogs. With ample stability, even less experienced runners can lace them up with confidence.
