ASICS Novablast 3 vs Novablast 4: Which One Is For You?

4 Mins read

As someone who restarted running in January 2024 after taking a break, I fell in love with the Asics Novablast 4 as it was my first proper running shoe. But after completing a 10k race, I’m curious – how do the previous Novablast models differ? Let’s explore the main differences between the Novablast 3 and 4 to help you find the perfect pair for your training.

ASICS Novablast 4

The Novablast 4 is best used as a daily trainer for neutral runners with high arches who heel or midfoot strike. Here’s why:

  • Durable and Stable: The combination of the FF Blast+ Eco midsole and a secure, woven upper gives ample cushioning and stability throughout runs.
  • Emphasis on Comfort: While the midsole offers some responsiveness, it prioritises comfort for easy runs and recovery days, making it a great option for short to mid-distance running. 
  • An Enduring Ride: Further enhancing the comfort experience, the Novablast 4 boasts an improved outsole compared to the Novablast 3. This translates to better durability, ensuring the shoe can withstand the demands of your training regimen while maintaining its plush cushioning over longer distances.

Being a neutral mid-foot striker myself, I found the Asics Novablast 4 to be the more comfortable running shoe due to its durability and medium width toebox. 

The Novablast 4’s medium width toebox has sufficient wiggle space if you want to spread your toes. No toe scrunching necessary, just pure comfort that goes for miles and miles.

Additionally, the FF Blast+ Eco midsole feels like it absorbs every impact during progression runs, which is important to avoiding long term joint pain and potential injuries, a strong indicator of durability.

However, unlike other super-soft running shoes, the Novablast 4 does not sacrifice stability. The secure woven upper hugs your feet securely, especially in the midfoot section, which prevents any unwanted wobbling.

ASICS Novablast 3

The Novablast 3 caters to neutral runners, particularly forefoot strikers who prioritise comfort during their runs. These are what sets it apart from the Novablast 4:

  • Enhanced Responsiveness: The FlyteFoam midsole in the Novablast 3 delivers a more responsive feel compared to the Novablast 4, making it a good choice for speed training while still being comfortable for daily runs.
  • Lightweight Design: Although the weight difference is minimal (3 grams), the Novablast 3 may feel slightly lighter for some runners.

Essentially, the Novablast 3 prioritises a balance between comfort and responsiveness, making it a versatile choice for either daily or speed runs.

Who is the Asics Novablast 3 a good running shoe for?

The Asics Novablast 3 is ideal for neutral runners, particularly forefoot strikers, who prioritise maximum comfort during easy runs and recovery days. 

Who is the Asics Novablast 4 a good running shoe for?

The Asics Novablast 4 caters to a wider range of neutral runners, including midfoot strikers. 

What's the biggest difference between the Novablast 3 and 4?

The most significant difference lies in the midsole. The Novablast 3 uses FlyteFoam while the Novablast 4 features FF Blast+ Eco. 

Can I use the Novablast 3 or 4 for trail running?

Neither shoe is specifically designed for trail running. They lack the tread patterns and protective features needed for off-road environments. Consider a dedicated trail running shoe if you plan on trail running.

How often should I replace my Novablast 3 or 4?

The lifespan of running shoes depends on various factors like frequency, distance, and terrain. Generally, running shoes need replacing after 300-500 miles (480-800 km) when the cushioning starts to lose effectiveness.

How should I clean my Novablast 3 or 4 after a run?

Remove the insoles and laces, and wipe down the upper with a damp cloth and mild soap. Let the shoes air dry completely before storing them.

Can I find used Novablast 3 or 4 shoes to save money?

While it is possible to find used pairs, it is typically not recommended to do so. Ensure the shoes are in good condition to avoid potential injuries.

I have a history of shin splints. Is the Novablast 3 or 4 better for me?

Both shoes offer good cushioning, but the Novablast 4’s slightly firmer midsole may be a better choice for those prone to shin splints. However, consulting a healthcare professional or running specialist is advised to avoid future injuries. 

I'm still unsure which Novablast model is right for me. What should I do?

Consider the factors most important to you – comfort, stability, responsiveness, etc. Reading reviews, comparing specs, and ideally, trying on both shoes can help you make an informed decision.
