The Asics Novablast 4. Everyday cushioning with a springy edge

The Asics Novablast 4 hits the pavement with a thick foam slab underfoot that feels almost like a mini trampoline when you step onto a wet city sidewalk after rain. Product manager Y?ki Tanaka describes it as the brand’s most playful daily trainer in the lineup.

High-stack foam and geometry

Asics Novablast 4 sits on a high-stack midsole built from FF Blast Plus Eco foam, a nitrogen-infused compound tuned for softer landings and noticeable rebound. Asics points out that at least part of this foam uses bio-based content derived from sugarcane, reducing the shoe’s materials footprint compared with earlier Novablast generations.

The listed stack height for the Novablast 4 is 41.5 mm in the heel and 33.5 mm in the forefoot for men, translating to a 8 mm drop that many runners will find familiar. Combined with a pronounced rocker geometry, the shoe encourages rolling transitions, letting you move from heel to toe with less effort on steady daily runs.

Upper fit and on-foot feel

On top of the foam, the Novablast 4 uses a engineered mesh upper with targeted zones of breathability over the forefoot and more structure around the midfoot and heel. Reviewers at RunRepeat note that the tongue is moderately padded, avoiding the overly thick tongues seen in some maximal trainers while still protecting against lace pressure.

Sliding into the shoe, testers at Believe in the Run describe a stable heel counter and a slightly generous forefoot volume that allows toes to splay on impact. The sensation, especially when you jog across a slightly uneven park path, is of a cushioned but not mushy base that rebounds without wobbling.

Outsole grip and durability

Underneath, the Novablast 4 features an AHAR (Asics High Abrasion Rubber) outsole with strategically placed rubber pods under the heel and forefoot and exposed foam elsewhere. Asics indicates that this layout balances weight savings with wear resistance, keeping the shoe relatively light for its stack while still offering a clear lifespan for regular training.

Lab measurements cited by RunRepeat suggest the men’s version in a US 9 weighs around 250 grams, squarely in the moderate weight range for cushioned daily trainers. Test runs on damp asphalt and compact gravel show the rubber sections providing reliable grip, while the cutouts in the outsole help the foam compress and release more freely.

Positioning in the Asics lineup

Asics options for everyday running now range from the more traditional Gel-Nimbus models with visible Gel units to the Novablast series, which leans into simple foam and geometry instead of heavy tooling. The company’s official product page frames Novablast 4 as a daily trainer with energetic cushioning rather than a pure long-distance plush shoe.

In interviews around the launch, chief product officer Koji Sato emphasized that the Novablast line aims to capture runners who want fun, bouncy runs without stepping into the more aggressive Superblast or racing-oriented carbon shoes. That makes Novablast 4 a bridge between entry-level neutral trainers and higher-priced performance foam models.

Market availability and pricing

Asics sells the Novablast 4 across major running markets, including Japan, Europe and the US, through its own ecommerce channels and specialist retailers. In Germany, the shoe is available via the Asics online shop and retailers such as Keller Sports and SportScheck, typically in a wide size run for men and women.

The official price on the Asics EU website for Novablast 4 is around 150 euros for the standard colorways at launch. In the US, Asics lists a MSRP of about 140 dollars, placing it slightly below some premium cushioned trainers such as Gel-Nimbus but above entry-level models like the Gel-Excite.

Classic profile and Sunday lens

Although Novablast 4 is a contemporary shoe, the product already fits a certain Sunday running ritual: light, bouncy, and reliable over medium distances. On a quiet morning loop, the pronounced midsole and soft foam give off a consistent feel that some runners describe as pleasantly lively rather than overly soft.

Running specialty sites increasingly mention the Novablast series when discussing classic neutral trainers that maintain a recognizable ride over successive iterations. That puts the shoe into a developing long-seller profile, especially for runners who return to the Novablast line rather than switching to more experimental models each season.

Context and Asics Corp. stock

Asics continues to highlight performance running as a core revenue pillar in its earnings presentations, with neutral trainers such as Gel-Nimbus and Novablast contributing steady volume alongside more technical racing products. For retail investors watching the sportswear sector, the Asics Corp. share on the Tokyo Stock Exchange reflects how consistently these footwear lines translate into sales, but the Novablast 4 itself remains a consumer-facing decision about comfort and ride, not a direct trading signal.
