Brooks Ghost 15 review

The Ghost 15 offers fantastic comfort, and it's a great choice for daily workouts, especially when cruising at slow or moderate speeds.

Moreover, this workhorse from Brooks showcases generous heel cushioning and an ultra-durable outsole, so in our view, it's an ideal match for heel strikers that tend to wear out shoes quickly in that area.

We don't recommend this shoe if you:

• prefer a lighter daily trainer. Check out the Brooks Glycerin 20 instead
• need a stability shoe. The Adrenaline GTS 22 is a better choice in the Brooks lineup
• love high-stacked and plush running shoes. Take a look at the ASICS Nimbus 25 for that

Furthermore, this shoe might not be the best choice for you if you're a forefoot striker. With its CRAZY heel-to-toe drop of 13.2 mm, there's an excess of foam in the heel and insufficient support where you actually hit the ground.

We suggest considering other options such as the Saucony Kinvara 14 or the New Balance Fresh Foam X More v4 instead.

Boasting a higher-than-average stack height of 36.3 mm, we're convinced there isn't a heel striker out there who could possibly need more cushioning than this.

Now, forefoot time. We measured it at 23.1 mm, so it's shy of the typical shoe, though we figure it's more than enough for the majority of runs.

That being said, midfoot or forefoot strikers might find this shoe a tad too slim for their longest runs. In those instances, we recommend adding a high-stack shoe like the Hoka Bondi 8 for those 20-milers.

Naturally, a skyscraper-high heel and a modest forefoot suggest a two-digit heel-to-toe drop. And there it is—we measured in our lab an eye-popping 13.2 mm, which is nearly 5 mm more than the average shoe and 0.8 mm more than the Brooks Ghost 14.

This shoe is a dream-come-true for heel strikers or those wrestling with Achilles or calf troubles. However, for midfoot or forefoot runners who doesn't suffer with lower-leg problems, we think there are better daily trainers in the market like the Hoka Mach 5.

Switching gears to the midsole, it hosts DNA Loft v2, a foam made from plain EVA. It's slightly disappointing considering the Glyceryn 20 boasts DNA Loft v3, a nitrogen-infused foam. But at the same time, at 15.9 HA, it's 29% softer than the DNA Loft v1 of its predecessor. Not bad!

And we genuinely enjoyed its ride—it's a blast and one of the softest shoes we've ever tested in the lab.

If you're interested in a deeper dive into midsoles and how do they work, don't hesitate to check our comprehensive guide, it's full of information!

In chilly weather, the midsole keeps its softness, scoring better than the typical shoe with a 24.5 HA rating.

But that's not a great result after all. The midsole gets 54.4% firmer in chily temperatures, which is a letdown.

Still, it's no surprise to us. After testing hundreds of shoes in the lab, we wrote a guide about how EVA foams are infamous for underperforming in Winter.

We were anticipating an ordinary insole, and that's exactly what Brooks provided. It's cozy, cushioned, and resilient—everything we need in a daily trainer!

Brooks clearly understands that this shoe must accommodate a variety of feet. For our medium-to-wide feet, the fit was amazing.

However, the truly exceptional aspect of the guys from Seattle is its renowned tradition of crafting the Ghost in... (drumroll, please...) four sizes!

From narrow and medium to wide and extra-wide, their approach makes this one as the "universal" shoe. In fact, only a select few models in the market boast such a range of width options.

We've noticed that the area for the big toe is somewhat wider compared to other shoes, which, in our view, is a positive aspect.

Given how soft the foam is in this shoe, we knew this wasn't going to be the most stable option. But to our surprise, it holds up pretty well!

It provided us sufficient stability for the majority of runs, much more than we initially expected.

This stability is because Brooks intentionally designed this shoe to minimise lateral motion. 

In our torsional rigidity test, it earned a 3 out of 5 rating—somewhat less than the average shoe but far better than many daily trainers. Take the Nike Pegasus 40 for example, it only managed to score 2 out of 5.

The Ghost 15 scored 5/5 on our heel counter stiffness test, meaning it's incredibly rigid in this area. Such a stiff heel counter benefits us by:

• Maintaining our foot alignment and minimising unnecessary sideways motion.
• Enhancing lockdown and boosting our confidence during quick, tight turns.

However, this advantage doesn't come without trade-offs. The stiffness can lead to discomfort, particularly during runs lasting longer than an hour. This felt for us like too high a price for the stability it provides in those long runs. However, it worked great for us during short easy and aerobic runs.

Indeed, kudos to Brooks for this move, straying from the conventional path rather than following the crowd.

The Ghost 15 it's your run-of-the-mill shoe when it comes to the width of the forefoot, nothing fancy to report. It just does its job, and it does it well.

Brooks had one more stability-enhancing feature up their sleeve. The Ghost 15 sports an impressively wide heel that we measured in the lab at 95.8 mm.

This further convinced us that the shoe designers in Seattle had heel-striking runners firmly in their thoughts when designing this one.

The Ghost series has always been renowned for being one of the more flexible daily trainers on the market. So, for the 15th edition, our stiffness lab test clocked it at just 9.5N.

This measurement is significantly lower compared to the majority of other shoes we've tried!

This running shoe maintains significant flexibility even in colder temperatures. In fact, it's nearly half as stiff as the average shoe.

Weighing in at 9.8 oz (279g), the Ghost 15 just slips under the critical 10 oz threshold, and it's in the same range that most daily trainers—except a few outliers.

The Brooks Ghost 14 was a great shoe, but the major criticism it got was about its lack of breathability. In fact, we awarded it a 3/5 in our smoke-pumping test, which is a disastrous result for a road running shoe.

Luckily, the Ghost 15 design lead to an improvement in this regard. As evident in the video above, it doesn't quite measure up to the jaw-dropping Saucony Triumph 20 in our lab, but it does surpass its predecessor, earning a commendable 4 out of 5.

Illuminated by our light, we revealed hundreds of well-positioned ventilation holes. And they work great! But what truly captivates us is their distribution—extending beyond the toebox, along the medial part of the shoe.

This feature makes the shoe a top-notch choice for those prone to blisters or similar issues in the arch of the feet. However, you may be thinking right now: if there are hundreds of ventilation holes, why it only achieves a 4 out of 5?

Well, let's uncover the reason. Beneath the ventilation holes lies a thin fabric. This layer enhances comfort but does so at the expense of airflow. Can you see that?

If you're still unsure, there's no better way than dissecting the upper and inspecting it up close. This way, the thin, comfort-enhancing yet airflow-restricting fabric becomes evident.

Daily trainers often rank low on the durability scale. Yet, even by these standards, when we subjected this shoe to our Dremel test, it's hard for us to recall a shoe that suffered more damage than this one.

So, don't bank on this shoe for hardcore durability. But for those of us who aren't notorious for wearing out shoes with our big toe or pinky toe, that's not a concern. We should be able to run on roads with them for their full lifespan without a problem.

The heel, constructed from a material akin to the toebox, does a slightly improved job, earning a 2/5.

While it's an improvement, it still falls short of our expectations for a £140 shoe, though it outperforms the upper (1/5). The Metaspeed Sky+ (right) easily outperformed the Ghost.

We clocked the hardness of the outsole at a substantial 84.4 HC in our lab. That's a notable 6% higher than your average shoe, which makes this robust model an exceptional choice for heavier runners who often wear out the outsoles of their running shoes first.

And the good news just keeps coming. We pulled out the Dremel again to destroy the rubber, and we received a mind-boggling result.

The tool only erased 0.40 mm of rubber, which leads us to believe this shoe has the long-haul durability to exceed 1000 miles for most runners.

Although the durability displayed by the previous two test was simply amazing, this result falls squarely into the average category. But it's fine!

We genuinely consider a 3.5 mm thickness ample for just about any everyday trainer—except perhaps when running on highly abrasive surfaces.

While the Ghost 15 does sport some reflective elements, we find them to be insufficient.

Sure, we're missing out on a gusseted tongue, but the heavenly cushioned padding more than makes up for it. This is one of the thickest tongues we've ever measured!

At 11.4 mm, it's a whopping 41% thicker than its predecessor and an impressive, plus 2x the average shoe.

In fact, they've used two separate pieces of plush foam in the tongue, a rare approach to attain this level of thickness.

Regrettably, there's one tradition they persist with that doesn't quite meet our expectations—the absence of gusset.

It would be great to see the Ghost equipped with a semi-gusseted tongue for enhanced lockdown, but it looks like we'll be keeping our fingers crossed until at least the 16th iteration.

We successfully managed to remove the insole and insert our own from various other models.
