The Asics NOVABLAST 4 entered the scene as an update to a beloved line that has consistently aimed to combine bounce and comfort in a lightweight package. With each version, Asics has refined its approach to energy return, comfort, and durability, looking out for runners who desire a cushioned yet responsive experience. So, does the NOVABLAST 4 tackle these aspects effectively, or does it merely offer an incremental upgrade? Let’s dive in.

Asics Novablast 4 Outsole

The outsole of the Asics NOVABLAST 4 features Asics’ AHAR™ (Asics High Abrasion Rubber) strategically placed in key areas for durability and traction. The forefoot and heel sections boast this durable rubber, while the midfoot features exposed foam with several cutaways to reduce weight and improve flexibility. The outsole lug design is moderately shallow, designed for road running but capable of handling light trail conditions.

[Our Take] In terms of performance, the AHAR™ rubber proves durable on both dry and wet surfaces while also delivering solid traction on roads (obviously) and paved paths. While it certainly won’t shy away from some dirt roads, gravel may be a bridge too far as some of the exposed outsole foam can get a bit chewed up. After about 40 miles, the outsole shows minimal wear, a testament to its resilience. However, those cutaways in the midfoot area can collect small rocks, which might be an annoyance if you’re frequently running on trails. Overall, the outsole balances durability and lightweight design well for everyday road use.

Asics Novablast 4 Midsole

The NOVABLAST 4’s midsole is made from Asics’ FF BLAST+ cushioning, a lightweight and bouncy foam that has become a hallmark of the NOVABLAST series. The midsole stack height measures 42mm in the heel and 34mm in the forefoot, for an overall 8mm drop. There’s no midsole plate included in this shoe, allowing for a more flexible and cushioned ride.

[Our Take] The FF BLAST+ foam truly shines here, providing an excellent balance of cushioning and responsiveness. The stack height contributes to a plush feel, absorbing impact efficiently without feeling too soft or sluggish. The energy return is pretty good for, especially during faster-paced runs, where the foam’s springiness becomes more pronounced. While the midsole cushioning is thick, the ground feel is good (though on roads, how much are you really “feeling”?), particularly in the forefoot, where there’s just enough feedback to keep you in tune with the terrain.

Asics Novablast 4 Upper

The upper of the Asics NOVABLAST 4 features an engineered mesh that aims to combine breathability and support. The material is light but sturdy, with reinforced areas around the toe box and midfoot for structure. The lacing system is traditional, though it includes partially gusseted tongues to prevent slipping during runs. Around the collar, there’s pretty good amount of foam working to lock in the heel.

[Our Take] Comfort is key with the upper design, and the engineered mesh delivers. It’s highly breathable, making it ideal for warmer weather or long runs where heat buildup can be an issue. The padding around the collar is plenty to secure the foot without creating any pressure points, and there’s a noticeable lack of hotspots, even after a long run. Durability is solid, with no signs of excessive wear or fraying after several runs. The tongue stays put during runs, thanks to the gussets, and the upper holds the foot in place well preventing slippage even on faster efforts.

Asics Novablast 4 Fit

[Our Take] The Asics NOVABLAST 4 brings a standard fit throughout, with a slightly wider forefoot that should work well for a variety of foot shapes. The toe box is roomy without feeling overly swimmy, while the midfoot and heel have a more locked-in feel. The shoe runs true to size, and the heel cup provides excellent lockdown without being overly rigid – though toward the midsole, the heel cup is beefy.

The fit of the NOVABLAST 4 is one of my favorite parts. The slightly roomier forefoot allows for natural toe splay, which is particularly appreciated on longer runs. The midfoot fit is snug but not constrictive, and the heel lockdown showed no sign of slipping, even when picking up the pace. On long runs, the shoe remains comfortable, with no irritation or pinching. The shoe feels cohesive as a unit, with each section contributing to a secure and comfortable fit.

Asics Novablast 4 Ride

[Our Take] The ride of the NOVABLAST 4 is where this shoe is one of those do-it-all trainers. The weight, coming in at approximately 285 grams (10 oz) for a men’s size 11, is lightweight enough to handle faster runs, yet the cushioning allows for a smooth and protective experience over longer distances. The bouncy FF BLAST+ midsole provides a lively, energetic ride you know well if you’ve run in previous versions.

This shoe shines in tempo runs and mid-to-long distances, where the combination of cushioning and responsiveness really comes to life. The flexible design allows for natural foot movement, while the bounce back from the foam encourages a quick turnover, making the shoe versatile enough for a range of runs, from daily training to race day.

Asics Novablast 4 Overall

The Asics NOVABLAST 4, priced at $140, continues to build on the strengths of its predecessors, offering a well-balanced blend of cushioning, responsiveness, and comfort. Its durable construction makes it a reliable daily trainer, while its lively ride makes it suitable for speedwork and long runs alike.

If you’re someone who enjoys a soft but springy ride wrapped up in a shoe that you’ll be comfortable going back to as a familiar go-to, the NOVABLAST 4 is worth considering.
