The ASICS Novablast series didn’t just change the running shoe market—it completely disrupted it. But with the release of the newer Novablast 5, the question isn’t just “is the Novablast 4 good?” It’s “does it still hold up against the shiny new model?”
After putting over 200 miles on the ASICS Novablast 4 during a grueling marathon training block, the answer is a resounding yes. While newer models push for lighter and softer, the Novablast 4 remains the reliability king. It matures the “wild” nature of the early Novablasts 1, 2 and 3 into something stable, propulsive, and incredibly versatile.
Here is my honest, road-tested review of the Novablast 4 and how it stacks up against the new Novablast 5.
ASICS Novablast 4 Specs: Weight, Drop, and Stack Height
- Weight: 9.1 oz (Men’s 9) / 7.9 oz (Women’s 8)
- Drop: 8mm
- Stack Height: 41.5mm (Heel) / 33.5mm (Forefoot)
- Midsole Foam: FF BLAST™ PLUS ECO
- Outsole: AHAR™ Lo Rubber
- Best For: Daily training, long runs, recovery runs, and marathon paces.
The Ride: Why I Fell in Love With This Shoe
I didn’t just test these shoes on a quick jog; I trusted them for my first-ever marathon training block. That is a vulnerable time for any runner and you need protection, but more importantly you also need to feel fast.
The defining feature here is the FF BLAST™ PLUS ECO foam combined with the unique geometric outsole. It creates this distinct “trampoline” effect. When you land, the pod-like outsole compresses, and as you roll through your stride, it snaps back.
I love the bounce effect the shoes give you. It almost feels like a trampoline propelling you forward.
Unlike some max-cushion shoes that feel like running in wet sand, the Novablast 4 has energy. It feels good at all paces—from slow recovery plods to faster tempo efforts.
The midsole is soft and keeps your legs protected over the long miles.
ASICS Novablast 4
- ✓Engineered woven upper: Offers advanced stretch, ventilation, and durability.
- ✓Trampoline-inspired outsole design: Helps provide a more responsive bounce back.
- ✓FF BLAST PLUS ECO cushioning: Made with approximately 20% bio-based content and helps provide cloud-like comfort.
Fit & Sizing: Upper Comfort and Breathability
One of the biggest complaints about earlier “super trainers” was the fit being too loose or unstable. ASICS fixed that here with an engineered woven upper.
The upper is snug and comfortable with zero lockdown issues. It feels premium, almost sock-like, but with enough structure to keep your foot centered on the platform. It is worth noting that this woven material is a bit thicker than standard mesh; while that feels luxurious and secure, it can run a little warm in peak summer heat compared to lighter racers.
Lifestyle Appeal: Is the Novablast 4 Good for Walking/Casual Wear?
Running shoes often look… like running shoes. Neon, aggressive, and hard to wear with jeans. The Novablast 4 breaks that trend. The geometric design looks futuristic but clean.
A big reason why I love the Novablast 4 is because they look good on the track and in casual settings. Whether you’re going to get groceries or running a 5k you can still look stylish and feel comfortable.
The Big Comparison: Asics Novablast 4 vs. Novablast 5
Most reviews compare this shoe to the old Novablast 3, but that’s old news. If you are shopping today, you are likely choosing between the 4 and the 5.
Here is the breakdown of the key differences:
ASICS Novablast 5
- ✓Breathable engineered jacquard mesh upper.
- ✓FF BLAST MAX cushioning: Helps provide a lightweight and energetic ride.
- ✓Designed to help improve visibility in low-light settings with reflective details.
1. The Foam Feel (Bounce vs. Squish)
The Novablast 5 introduces a new formulation that feels softer and airier. However, the Novablast 4 feels more consistent. The 4 offers a slightly firmer, more responsive pop. If you prefer a shoe that stabilizes you rather than squishing underneath you, the 4 is actually the better choice.
2. The Upper (Woven vs. Mesh)
The Novablast 4 uses a Woven upper, while the 5 moved to a Jacquard Mesh.
- Novablast 4: Feels more secure, durable, and premium. Better for cooler weather or runners who need stability.
- Novablast 5: More breathable and lighter, but sacrifices a tiny bit of that “locked-down” structure.
3. Price & Value Analysis
With the release of the 5, the Novablast 4 often sees price drops. Given that the ride is 95% similar, the Novablast 4 is arguably the best “bang for your buck” daily trainer on the market right now.
Final Verdict: Is the Novablast 4 Right For You?
If you are a runner who doesn’t want to buy a rotation of three different shoes (one for speed, one for recovery, one for racing), this is the solution.
The Novablast 4 is easily the shoe I would recommend if you could only have one shoe in your lineup to do everything from the 5k to the marathon.
It is stable enough for high mileage, bouncy enough for tempo days, and durable enough to last 400+ miles.

Frequently Asked Questions (FAQs)
How does the Novablast 4 compare to the new Novablast 5?
The biggest difference is the “feel” of the bounce. The Novablast 5 uses a newer foam (FF BLAST™ MAX) that is noticeably softer and squishier. While some runners like that “sinking” feeling, I found the Novablast 4 to be more consistent and stable. The 4 is slightly firmer, which makes it feel “snappier” when you want to pick up the pace, whereas the 5 leans more into pure recovery-style comfort.
Is the Novablast 4 good for wide feet?
Yes and no. The Novablast 4 has a slightly wider base and a more accommodating toe box than previous versions (like the Novablast 3). However, the woven upper is quite structured. If you have true wide feet, you might find the midfoot a bit snug. ASICS does offer a Wide (2E) version, which I’d highly recommend if you usually struggle with narrow fit.
Can I use the Novablast 4 for a full marathon?
Absolutely. In fact, it was my primary shoe for my first marathon training block. Over 200+ miles and multiple 18–20 mile long runs, the leg protection was top-tier. It isn’t as aggressive as a carbon-plated racer, but for 99% of runners, it provides the perfect mix of “trampoline” bounce and long-distance comfort to get you through 26.2 miles.
How many miles will the Novablast 4 last?
Most runners can expect 400 to 500 miles out of the Novablast 4. In my testing, the FF BLAST™ PLUS ECO foam held its “pop” remarkably well even past the 200-mile mark. The AHAR™ Lo rubber on the outsole is also quite durable, though you may notice a slight drop in traction on wet pavement once you cross the 300-mile threshold.
Is it stable enough for overpronators?
The Novablast 4 is a neutral shoe, but it is what we call “stable neutral.” It has a very wide footprint and sidewalls that wrap around the heel, which helps keep your foot centered. If you have severe overpronation, you’ll likely need a dedicated stability shoe like the Kayano, but for neutral runners or those with very mild instability, the 4 is much safer than the earlier, “wobblier” versions of this shoe.
Does the shoe run true to size?
Yes, the Novablast 4 fits true to size. I wore my standard running shoe size and found the lockdown perfect with no need for a runner’s knot. The heel collar is plush and secure, and the gusseted tongue stays in place without sliding.
Is the ASICS Novablast 4 good for walking and standing all day?
Yes, it is actually one of the best “crossover” shoes for walking. Because the “trampoline” effect relies on compression, you feel that soft, energy-returning bounce even at a walking pace.
Unlike aggressive racing shoes that can feel awkward or “tippy” when walking, the Novablast 4 has a wide, stable base that makes it very comfortable for long days on your feet.
