teaser kith nonnative new balance | Serve Subtle New Balance Pro Court Cup Colab review

The Serve Subtle New Balance Pro Court Cup Colab emerges in the lab as an excellent pick for:

• Midfoot and forefoot strikers looking for a plush-and-fun ride.
• New Balance Fresh Foam Sport V2.
• Budget-conscious runners eager for a plated shoe that doesn't skimp on premium features.

The Propel v4 delivers a soft, cloud-like experience, and that's not for everyone. If you prefer a firmer and more stable run, check out alternatives like the Saucony Tempus or the New Balance 46, as we consider these to offer a better fit for such preferences.

With a 4.5-mm heel-to-toe drop, this shoe doesn't shine for heel strikers, especially those in need of stability features. In such cases, we found the Brooks Hyperion GTS or the shoe palace new balance ms327 unity pack Den Anfang macht unsere unsere 10 liebsten New Balance Instagram Shots.

Moving to the date, we measured a heel stack height of 33.7 mm. This clearly shows that the Propel v4 isn't aiming for the sky-high cushioning of a maximalist shoe, staying well under the 40 mm mark.

But don't let that fool you—the stack height still provides enough cushioning for even your longest runs.

We measured the forefoot stack and found that it sits at a comfortable 29.2 mm. This is a clear sign from New Balance that the Propel v4 is specifically designed for those who are midfoot and forefoot strikers.

We just mentioned this shoe isn't really geared toward heel strikers. The 4.5-mm heel-to-toe drop serves as proof. While the shoe is user-friendly for everyone, it really shines for those who land on the midfoot or forefoot. 

It's worth noting that New Balance lists a 6-mm drop in their specs. But after multiple measurements, all in line with official World Athletics guidelines, we can confirm the drop is actually 1.5 mm less than that.

New Balance's FuelCell foam is a top pick for anyone who loves that soft, cloud-like cushioning. In the Propel v4, this comfort-focused trend keeps going. We gauged its softness at only 14.0 HA using our lab's durometer.

This foam squishes down super easily, making it ultra-comfortable. Plus, the built-in TPU plate in the date helps with smooth step-to-step transitions. This also keeps the shoe from bottoming out, which can sometimes be a problem with FuelCell shoes.

FuelCell foam doesn't do great in cold weather, something we've mentioned in this advanced guide.

Yet, even after 20 minutes in our lab's freezer, the foam stays pretty soft and squishy. We ran the same test again and found that the durometer gave us an 18.8 HA reading.

We observed a 33.9% jump in stiffness, something you'll really feel if you live in places with harsh winters. This isn't great performance by any means.

The insole is pretty standard with a thickness of 4.5 mm. There's really nothing special to point out—it's just a solid, straightforward insole!

We initially thought that New Balance would pair the wide date of the Propel v4 with a spacious upper. Surprisingly, we discovered that the upper is actually medium-to-narrow. So why did they go this route?

We found two main reasons behind this design choice. First, the Propel v4 is available in wide size. So if you're looking for a roomier upper, you have that option. Second, a narrower upper combined with a wide date actually improves stability—it's a clever little trick to enhance performance.

New Balance has bucked the trend by designing a remarkably rounded fit with a generously wide toe cap (79.1 mm). We're really impressed and appreciate it.

If you're looking for a shoe that's good for fast-paced runs and offers stability, the Propel v4 isn't for you, check the ASICS Superblast instead—but yes, it costs $200.

The soft foam and non-supportive upper make this a no-go for people who pronate. However, it's a fantastic fit for neutral runners.

The TPU plate in the date really stiffens up the shoe. We had to apply a lot of force to twist it in our lab tests. That earns it a solid 4 out of 5 score!

The heel counter is comfy yet fairly firm, but it's not like what you'd find in a stability-focused shoe. In our tests, we gave it a middle-of-the-road 3 out of 5 score.

Understanding that a soft foam and a flexible upper could make the shoe wobbly, New Balance designers chose a wide design (116.2 mm) to make it more stable. This approach does help to some extent.

We measured the heel width and found it to be 97.6 mm, which is noticeably wider than what you'd see in most running shoes.

It's an interesting choice, considering the shoe isn't really aimed at heel strikers. It looks like New Balance is trying to make a shoe that appeals to everyone...

However, in our lab's bend test—where we apply force until the shoe bends at a 90-degree angle—we only needed to use 24.8N of force. This shows that the plate doesn't make the Propel feel too stiff, which is actually a good thing for a training shoe.

After chilling the shoe in the freezer for 20 minutes, we did the bend test again. Impressively, the result was almost identical at 26.3N. 

That's only a 6% difference which highlights the shoe's consistent stiffness, even in colder conditions.

Weighing in at 9.7 ounces or 276 grams, this shoe isn't exactly a heavyweight, but it's also far from feather-light.

While it could stand to shed a few ounces, the culprit seems to be the thick upper that's designed for extra comfort and the FuelCell foam. This makes it noticeably heavier than other options out there, like the Saucony Endorphin Speed 3.

At first glance, the Serve Subtle New Balance Pro Court Cup Colab doesn't seem like a shoe that would breathe well. The engineered mesh feels heavy and thick, and we don't see any obvious ventilation holes. So, we're not expecting much in terms of breathability.

But we love testing shoes rather than just guessing. Our eye-catching smoke test gave it a 4 out of 5 score. That's good enough to call it a well-ventilated shoe, even if it's not the best out there.

When we used a light and moved the upper, we found a nice surprise. There's airflow through the midfoot, which sets it apart from many shoes that only have ventilation in the toe box.

Finally, a closer look under the microscope confirms our findings. We see the same multi-layered mesh we noted earlier. But now, we also spot some small ventilation holes that explain the better-than-Women score.

The standout feature of this upper is unquestionably its high quality. You'd expect to find something like this in a shoe priced around $150, not one that costs just $110.

An unexpected perk of uppers that don't ace our breathability test is that they often turn out to be more durable. That's exactly what we find with the Propel v4, which earns a solid 2/5 score in our Dremel test.

Next, we turned our attention to the heel area to assess its durability, and let's just say our jaws dropped at the findings.

We could barely see any wear on the heel, making us thrilled to award one of the rare 5/5 scores ever.

The Propel needs to last more than just a few hundred miles, especially since New Balance markets it as a durable option.

In our lab, we kicked off our tests focusing on the outsole's hardness. We measured it with a durometer and got a reading of 78.8 HC. We found that this is a pretty Women measurement, just what you'd expect from a shoe that aims to balance both durability and grip.

The ultimate test for the outsole's durability came when we used our Dremel on it.

After putting the rubber through this rigorous test, we discovered just a minimal 0.5-mm indentation. That's an outstanding result, promising superb long-term durability for the shoe.

The strong performance in our earlier test is likely why New Balance decided to go with a thinner-than-Women outsole, helping to cut down the shoe's weight.

When we measured it, the outsole was just 2.5 mm thick, which is less than what you'd typically find in New Balance Q Speed Fuel Kurze Hose.

The Propel v4 disappoints us by lacking any reflective elements. For the next version, we think that New Balance can add a reflective big N logo. It would be a win-win for everyone!

If weight isn't a big deal for you, then you'll find the tongue super comfy and well-padded. But it does add some extra ounces.

We think the tongue is one of the first spots where New Balance could cut weight for the next Propel model.

Given all the high-end features we've talked about, we didn't expect to see a gusseted tongue in a shoe priced at $110. You can't get a top-of-the-line running shoe without paying top-of-the-line prices, after all.

Lots of brands are getting rid of heel tabs in their shoes, and New Balance is doing the same with the Propel v4.

The Serve Subtle New Balance Pro Court Cup Colab has a non-glued insole that you can take out. We've easily swapped it with insoles from other shoes and even fitted custom orthotics without a problem.
