Streakfly vs. Vaporfly: Design and Build

The Vaporfly

The Vaporfly sports shoe model boasts an extensive product lineup since its first release in 2017, with the latest — the NEXT3% having just launched in March this year(2023).

Throughout its various generations, the Vaporfly has undergone several revisions to its upper design, always striving for minimal weight. The focus has consistently been on creating an upper that is as lightweight as possible. 

In line with this philosophy, the outsole of the Vaporfly follows suit by featuring a minimal amount of rubber coverage on the forefoot, accompanied by two strips at the back of the shoe. This well-chosen placement offers adequate grip without affecting the shoe’s overall weight.

The midsole magic

The true magic of the Vaporfly lies in its midsole design. Throughout each iteration, the Vaporfly has consistently featured a full-length carbon plate nestled within a substantial stack of Nike’s ZoomX foam.

Their unique combination comprises a lightweight and remarkably plush PEBA-based foam boasting exceptional softness and energy return. 

Working harmoniously with the carbon plate, this setup delivers a propulsive and comfortable ride. The fusion of the carbon plate and ZoomX foam creates a winning formula that propels runners forward by providing optimal cushioning and support.

Regarding the NEXT3%, the ZoomX foam midsole is 30% lighter and 50% more responsive than the previous Vaporfly models. The carbon fiber plate is further optimized to provide even more energy return.

The Streakfly

The Streakfly boasts a heel stack height of 32mm, providing significantly more cushioning than traditional racing flats. Despite this added cushioning, the shoe still falls well below the 40mm limit established by World Athletics. 

In contrast, the Nike Vaporfly NEXT% 2, known for its carbon plate technology, approaches the upper limit, maximizing its stack height for enhanced performance.

Ultra lightweight

Unlike the Nike Vaporfly models, the Streakfly does not incorporate a carbon plate within its midsole. Instead, it utilizes a Pebax shank in the midfoot area to facilitate a responsive and efficient transition.

This distinctive design accentuates the shoe’s snappy feel, contributing to its lightweight construction. 

Weighing in at a mere 182g for a UK men’s size 9, the Streakfly is an exceptionally lightweight option in running shoes. For more context, most carbon-plated shoes surpass the 200g mark, with many exceeding 230g in similar sizes.

Despite lacking a carbon plate in the midsole, the Streakflt still features a full-length ZoomX midsole crafted from the same PEBA-based foam used in the Vaporfly and Alphafly.

To maintain its lightweight design, the Streakfly boasts a fairly minimalist outsole. However, Nike has designed the outsole to provide optimal traction during sharp turns and high-speed running.

Streakfly vs Vaporfly: Running Performance

The Streakfly and Vaporfly duo are top-of-the-line running shoes with distinct salient points performance-wise.

Streakfly

For the most part, running in the Streakfly has been a delightful experience. It truly comes to life when you pick up the pace and hit faster speeds.

Its responsiveness and snappy transition support did not disappoint, delivering just as advertised. Complemented by the bouncy foam, the soft ride provides a spring-like effect that propels you forward with each stride.

Even better, the Streakfly offers impressive grip even on slightly slick outdoor tracks, ensuring confidence and stability at fast paces. That said, the Streakfly may offer a different level of satisfaction during slower paces.

Some runners have found the cushioning to feel spongy, which typically will diminish its optimal effectiveness when running at a more relaxed or conversational pace. 

As a result, the Streakfly may not be the most versatile choice if you’re looking for a shoe that performs equally well across different speeds and intensities.

However, when used as intended for faster workouts, tempo runs, or races, the Streakfly truly adds finesse to your performance.

What we like about the product

Here’s a summary of what we like about the Streakfly in general:

• Lightweight design, weighing only 182g (UK men’s 9), making it one of the lightest options available.
• Utilizes Nike’s ZoomX foam in the midsole, known for its exceptional softness and energy return.
• It incorporates a Pebax shank in the midfoot, promoting a snappy transition and enhancing the overall running experience.
• Provides a comfortable and cushioned ride, thanks to the full ZoomX midsole.
• It offers impressive grip and traction, even when rounding corners at high speeds.
• Ideal for shorter repetitions, such as 200 or 400 meters, where its responsiveness and lightweight build shine.

Vaporfly

The Vaporfly is not just another racing shoe but a game-changer developed to help athletes maximize their potential over long distances.

And it has delivered exceptionally well. In the first iteration of the NEXT4%, the Vaporfly was touted to improve users’ running economy by as much as 4%, which means that your ability to run faster and longer can improve by as much as 4% holistically. Ridiculous right?

Yeah, well, the results certainly speak for themselves. Athletes have gone on to win medals and championships thanks to their performance.

It was so successful that the World Athletics issued a soft ban on the shoe for competitive races.

With subsequent generations of Vaporfly, the underlying technology becomes more refined. The shoe provides one-of-a-kind protection and cushion for a lightweight racing shoe.

The newer NEXT3% advances the peculiarities of the shoe line further, reflecting the improved pop and responsiveness stats dominantly on the tracks.

It’s important to note that while the shoe sports an imposing range of support features and high-performance stats, it’s only a tool. It’s not a substitute for proper training and preparation.

What we like about the product

Here’s a summary of what we like about the Vaporfly in general;

• It incorporates a full-length carbon plate that enhances the user’s running economy and propels runners forward with each stride.
• Utilizes Nike’s ZoomX foam in the midsole, providing exceptional softness and energy return for a responsive and cushioned ride.
• It offers a high stack height of foam in the midsole, proscribing superior protection and cushioning while maintaining a lightweight design.
