ASICS Novablast 4

The Asics Novablast 4 arrives with the complicated mission of improving a shoe that was considered in 2022 as the best shoe of the year for RUNNEA users throughout Europe. After running with them for more than 150 km and attending the official presentation of the shoe at the Asics headquarters in Madrid, I bring you my conclusions. Will they manage to surpass their predecessors, the Asics Novablast 3? Let's find out.

Ideal type of runner: For a versatile runner.

The Novablast 4 is ideal for runners with a neutral stride or those of you with a corrective insole who are looking for a lightweight, fun, cushioned shoe. They are perfect for those of you who run 1 or 2 days a week to clear your head, or for those of you who are looking for a second pair of shoes in your rotation for training and running at medium to easy paces. You will be able to use them for competition, from a 10k to a marathon, if you prioritize comfort with a certain dynamism. And for training sessions, from running to series at not excessively brisk paces. Novablast 4 are ideal for runners looking for a dynamic, versatile and stable shoe.

Design and aesthetics

At first glance, the Novablast 4 maintain the modern and attractive aesthetics of Novablast 3, but with updates to the shape of the midsole and upper, offering a more refined and contemporary look. The colors we have seen so far are electric and monochrome. We are sure that as the months go by we will see new designs, as happened with the Asics Novablast 3.

The best of the shoe, its midsole.

One of the most notable updates to the Novablast 4 is the introduction of FF Blst + ECO foam in the midsole. Although visually on the shoes it simply reads FFBlast+, it is actually FFBlast+ ECO. The ECO variant of this foam integrates 20% materials from renewable sources, specifically from waste left over from sugar cane processing. This shift reflects the current trend among running brands towards more sustainable and "green" practices, an aspect increasingly valued by consumers aware of the environmental impact of their choices.

It is not only the composition of the midsole that has evolved in Novablast 4, but also their design. The rearfoot area of the midsole features renewed geometries that, together with the new outsole layout, contribute to a smoother stride transition and enhance the "springboard" effect. This feature is key to delivering a more dynamic and efficient running experience, allowing runners to enjoy a greater sense of propulsion.

Comfort and fit

The upper of the Novablast 4 introduces engineered mesh for breathability and a more adaptive fit. The tongue and collar have been redesigned for a more secure and comfortable fit. We are looking for more comfort while running, trying not to lose that sparkle that makes the Novablast range a dynamic shoe that responds when you demand it.

Slightly heavier but more breathable

Although slightly heavier than the Novablast 3, the Novablast 4 offer a more comfortable fit and greater breathability thanks to their redesigned upper.

Outsole

The outsole of the Novablast 4 has been designed to complement the midsole, offering additional cushioning and stability in addition to good grip. The improved outsole construction provides a more dynamic response at toe-off compared to Novablast 3.

Differences from the Asics Novablast 3

• Design: The Novablast 4 maintain the modern aesthetics but with a more refined design.
• Midsole: Optimized foam distribution for better rebound and transition feel.
• Upper: Improved breathability and adaptive fit in Novablast 4.
• Outsole : Improved traction and durability in Novablast 4.
• Versatility: Novablast 4 offer a wider range of use for different types of training.

What I liked most

The combination of comfort and performance, along with significant improvements in stability, breathability and adaptability of the upper, keeps the Novablast 4 as good as they were in their previous version.

Possible points for improvement

Although the improvements are notable, it is true that the search for greater stability makes the Novablast 4 somewhat less dynamic than the previous version. They lose some speed but gain more stability and control in running. It may not please everyone.

Rivals of the Asics Novablast 4

The Asics Novablast 4 represents a subtle yet meaningful progression from its predecessors, not so much in the scope of its improvements but in the direction towards which the model is evolving. This evolution brings about notable enhancements in stability, comfort, and fit, albeit at the expense of some versatility and the lively, bouncy sensation characteristic of the Novablast 3. The Novablast 4 shifts focus towards offering a running experience that prioritizes comfort, enhanced stability, and optimized performance at moderate speeds. The design remains visually appealing, with an increased emphasis on sustainability, making the Novablast 4 a compelling choice for everyday runners seeking a dependable shoe for a wide range of paces and distances, suitable for anything from a 10k to a marathon, ideally at paces no faster than 4:30m/km.

While I appreciate the more substantial feel of the Novablast 4, it prompts me to ponder the positioning of the Asics Cumulus 25, as the Novablast begins to closely resemble it.

The running experience provided by the Novablast 4 remains highly satisfying. Donning the shoes gives a noticeable sense of elevation, coupled with considerable comfort. The cushioning is slightly firmer yet remains quite accommodating. The evolution of this line over just four years is truly remarkable, showcasing incredible growth and improvement. The Novablast 4 stands as a reliable choice, underlining its status as a safe investment for runners.
