It feels like yesterday I started reviewing the 1080-running shoes series. I was working at a running specialist and tested version 6 – the very first from . Now, 9 years later, I'm here feeling slightly older, behind a computer writing about the newly launched New Balance Infinion 1080 v15, my first time writing about 1080 without Fresh Foam in the name.
Since then, Fresh Foam has evolved greatly. Fresh Foam X was introduced in the legendary 1080 v10 with its 3D-shaped heel design, and in 1080 v13, it developed again, becoming extremely soft and comfortable – with a more fashion-inspired look.
But one thing has remained fairly consistent: A Fresh Foam shoe always feels incredibly soft with a nice bounce initially. But over time, it settles, and the trampoline-like spring from the first runs tends to become more muted, ending in a softer, mattress-like feel. I find this has changed in New Balance 1080 v15.

Out with the old, in with Infinion – New Balance Infinion 1080 v15
The new foam sounds like something straight out of a Back to the Future or Tron movie: INFINION. This marks the first time New Balance utilizes supercritical foam in their everyday running shoes.
What is supercritical foam, you ask? It's when a gas like CO₂ or nitrogen is injected into the foam process, giving the foam unique properties regarding bounce and durability. It sounds odd, but it works.
This is quite a significant change – almost a paradigm shift – from what the New Balance 1080 series has been previously. For regular 1080 runners, it might seem like a big change, but I don't think you'll be disappointed with what you get in this new model.
A balancing act – New Balance Infinion 1080 v15
The new INFINION midsole is said to be more resilient than their previous foam, meaning it keeps its bounce and energetic feel much longer. With this change, it seems New Balance wants the Infinion 1080 v15 to be a more versatile do-it-all shoe, capable of handling both long, slow runs and offering a faster experience when needed.
You might say it balances on the edge between slow and fast, maintaining balance longer than we've seen in other New Balance shoes.
Recently, I've started preparing for the London Marathon, and last week I had a base run followed by 6 longer stride runs at 10k pace. The total run was 15 kilometers, and normally my go-to shoe for that type of session would be a super-trainer or a faster tempo shoe. But with the new midsole, I can actually use the new 1080. It offers a very comfortable running experience on the easy parts and a slightly firmer, more energetic feel when you speed up.
Another factor making this a balanced shoe, capable of handling different run types, is the weight reduction. A lighter shoe generally feels better when running fast, and in the new Infinion 1080 v15, New Balance has managed to make the shoe lighter without sacrificing comfort.

A lighter shoe generally feels better when running fast, and in the new Infinion 1080 v15, New Balance has managed to make the shoe lighter without sacrificing comfort. As always, a shoe made to be a comfortable everyday trainer will never feel as light and fast as a speed-focused shoe. But in a running shoe market with so many “must-have” categories, it's nice to have a shoe that simply does a bit more – and does it in a satisfying and balanced way.
The Upper – New Balance Infinion 1080 v15
The new shoe fits my feet really well. The toebox has enough room for longer runs, and the comfort is spot on. The double mesh upper is very comfortable to wear, and the padding is adequate without being too much.
When it comes to breathability, I think New Balance Infinion 1080 v15 hits a good balance, not making your toes too cold in winter, nor too warm in summer. However, I'll have to wait to test this, as it's currently quite cold and wet in Denmark.
The only thing not quite to my taste is the heel counter, which feels a bit low – especially on the inside of the heel. I had no issues with heel slip during runs, but I know from experience that some runners don't like a shoe that's too low in this area.
Lengthwise, New Balance 1080 v15 is true to size: I usually wear US 11, and it fits me perfectly here too.
Pick and choose – New Balance Infinion 1080 v15
With the success around and its impressive capabilities as both a tempo shoe and everyday shoe, New Balance has three strong alternatives that easily serve as your daily workhorse and partner to the race shoe.
FuelCell Rebel v5 will be the obvious choice for many if you want a lighter shoe that handles faster runs better, but the new 1080 v15 now performs better at higher speeds and has a more durable construction. Despite a higher price, it will probably be a more economical choice in the long run. Especially if you enjoy long runs. Here, the stability and comfort in New Balance Infinion 1080 v15 really shine.
I love this new update – not only because the foam lasts longer and is more fun to run on, but also because More v6 and 1080 v14 have been a bit too close in recent years.
The choice is clearer now:
If you want the softest shoe possible, choose
. If you want a more versatile everyday trainer – a shoe for both long and fast runs – choose New Balance Infinion 1080 v15. And if you're a lighter runner, or want a shoe that's more lively and better for speed, choose New Balance Rebel v5.
No matter what you choose, you'll get a fantastic shoe that helps you feel good and have fun on your runs.
