Hoka Challenger 7 GTX review

We think the Hoka Challenger 7 GTX is an outstanding choice for:

• Hoka enthusiasts looking for a versatile, waterproof door-to-trail running shoe.
• Runners with narrow-to-medium width feet seeking a reliable Gore-Tex shoe for their rotation.
• Fans of the Hoka Challenger series who desire a more durable option for just an extra £20.

If you have wide feet, the Challenger 7 GTX might not be the best fit, as its toebox, particularly around the toe area, is really narrow based on our lab tests. Luckily, we found that alternatives like the Nike Pegasus Trail 4 GTX provide ample room for toe splay and the same Gore-Tex membrane.

Also, the Challenger isn't the top Gore-Tex shoe if you're more trail-focused than road. In such cases, we suggest the Speedgoat 5 GTX, which boasts an impressive Vibram outsole and greater agility for various trails, not just the easy ones.

If you're searching for a maximalist and versatile shoe, there aren't many options like the Challenger 7 GTX.

With 39.2 mm of CMEVA foam in the heel, it offers heavy cushioning and guarantees exceptional comfort during long runs for every runner, including those who are extreme heel strikers.

In the forefoot, our precise measurement showed a stack height of 28.1 mm, higher than what's typical in trail running shoes, again emphasising comfort for long runs.

However, runners who prefer a strong ground feel on trails might find this disappointing and might be better off with a less cushioned shoe.

Our results lead to a massive 11.1 mm heel-to-toe drop, a big shift from the 5-mm drop Hoka claims. We frequently find this brand's measurements significantly different from ours.

Why the difference? We measure every shoe following World Athletics guidelines, but many brands don't adhere to these standards...

In the midsole, we encountered Hoka's familiar CMEVA foam, commonly used in many of their road running shoes.

This foam may not offer the plush ride found in other Hokas, but it provides a more harmonious balance. That's a major plus in our view for a hybrid shoe designed to perform well in any environment.

We then froze the shoe for 20 minutes next to our ice creams and re-tested it to evaluate its softness in cold temperatures.

The result? A hardness of 21.4 HA, which is pretty similar.

Actually, it's just a 9.7% change, which is pretty minor and right up there with the best foams on the market.

This also means no matter how cold it gets outside, you've got a shoe that'll give a solid performance... and one less excuse to skip the workout!

The insole is average, measuring 5.0 mm. It's made of plain EVA and offers enough comfort, with nothing negative to note about it.

One common worry among some Hoka runners is the width of the toebox, as they often designs uppers that are too narrow for the average foot. This is where we at RunRepeat step in to assist, by taking precise measurements of each upper and comparing them.

For the Challenger 7 GTX, the upper is average at 98.2 mm in its widest part, making it a perfect fit for those with normal feet. If your foot size is on the extreme ends, bear in mind that Hoka doesn't offer the GTX version in a 2E size, yet it does in the regular one.

In that scenario, your best bet might be to go half-size up or, if you're a woman, opt for the men's version if the colorway appeals to you.

While the widest part of the upper is average, the big toe area tapers significantly and tends to be narrow at only 73.5 mm.

What does this mean? Well, if you have feet that remain wide at the toes, this shoe might cause too much pressure on your feet...

With such a massive stack height, we were curious to see if the shoe would offer a stable ride. In our opinion it should, as it's undeniable that this shoe is designed for neutral runners and for those with mild pronation issues.

It's also true that it provides one of the most stable experiences we've ever had in a trail running shoe. Let's dive into why.

The first and one of the main reasons for this shoe's stability is its tremendous rigidity. We rated it 5 out of 5, similar to a shoe with a stiff rock plate or carbon plate, even though it doesn't have one.

This rigidity forces the shoe to move in a straight line. However, this can be a downside when taking sharp corners or navigating serpentine descents. So, keep that in mind based on the terrain you plan to run on.

The same high rating applies to the heel counter (5 out of 5), which is also crucial in explaining why the shoe feels so controlled. Think of it like a stability shoe in certain aspects—rigidity, heel counter stiffness—but without specific guidance elements like medial posts or guidance pieces.

That's why we see individuals with moderate stability needs using this shoe without any problems, but we still believe it's still best suited for neutral runners.

The final source of enhanced stability comes from the midsole. In the forefoot, Hoka opted for a wider than usual design, measuring 116.4 mm in width.

This width boosts stability but does make the shoe slightly clunkier. However, this is minor compared to the heel...

The heel dimensions are enormous at 100.9 mm, similar to most stability shoes like the Hoka Gaviota 5.

Combining the shoe's rigidity, the sturdy heel counter, the midsole's dimensions, and the significant drop results in a shoe that even heel strikers with high stability needs can use.

Marketed and designed as the perfect all-day, road-to-trail shoe, we anticipated it being a bit more flexible for improved hiking comfort. Yet, the oversized midsole undeniably contributes to increased stiffness.

Therefore, in our stiffness test, where we apply force to bend the shoe to 90 degrees, we recorded a result of 34.5N, which is higher than what we think it should have been.

We performed the same stiffness test under cold temperatures, after leaving the shoe in the freezer for 20 minutes, to see if the underfoot stiffness changed.

In these conditions, the shoe was significantly stiffer, showing a result of 45.0N.

This marks a 30.6% increase in stiffness, which isn't overly alarming, but it's definitely noticeable.

We had higher expectations for the shoe's performance based on the earlier softness test, but unfortunately, it fell short.

At 9.9 oz (281g), the Challenger 7 ATR remains reasonably light, even managing to stay under the 10-oz mark. However, this is a noticeable increase from the 8.8 oz (250g) of the non-GTX version. The added weight is understandable though, given the GTX membrane and extra protective layers.

Is it worth the extra 1.1 oz and £20 for increased durability and waterproofness? That depends on your needs...

When we tested the regular Hoka Challenger 7, we noted its below-average breathability, scoring just 2 out of 5 in our lab tests. So, we were really surprised to give the Gore-Tex version the same score, as waterproof editions tend to lose some airflow.

The minimal breathability happens mostly through the tongue. However, as seen in our video where we move the shoe over light, there are some breathable spots with fewer reinforcements in the midfoot and toebox.

We then used a microscope to inspect the upper.

It's made of a thick mesh combined with a Gore-Tex Invisible Fit membrane, consisting of 70% recycled polyester, which is a big plus. And there are some thinner spots here and there to improve airflow.

While some shoes place the GTX membrane outside the upper, Hoka integrated it inside.

Thankfully, the upper remains really comfortable and retains all the comfort features of the non-GTX edition.

The Challenger 7 GTX, a lightweight shoe, impressively packs a solid amount of protective layers in the upper, earning a perfect 5 out of 5 in our initial Dremel test. And it's worth mentioning that this robust TPU layer that enabled the perfect score is absent in the regular edition.

Sure, the results might have varied in the mesh area, but we're committed to maintaining standardised testing. That's why we test the exact same spot on every shoe, applying the same force and RPM, to ensure consistency and fairness.

The heel isn't quite as durable, as it scored a 3 out of 5 in our second Dremel test.

However, this result is by no means disappointing—in fact, it surpasses the performance of the average trail running shoe.

Hoka has consistently struck the right balance between road and trail performance with the Challenger series outsole, and the 7th edition is no exception.

It features the same Durabrasion rubber we saw in the regular version. With a hardness of 81.0 HC, it's a great approach, ensuring a good amount of grip without sacrificing too much durability.

Given its hardness, we expected at least average durability, and that's precisely what the Challenger 7 GTX delivered in our lab tests.

After our final Dremel test—enough for today—we observed a 0.8-mm indentation, a solid result for this shoe.

With an outsole thickness of 2.1 mm, we anticipate no trouble here, even after many hundreds of miles. This durability is thanks to the substantial lugs on top of the rubber, which we'll cover later in this review.

We took a final look at the outsole to examine the lugs Hoka chose. This time, there's no Vibram outsole, but the Durabrasion rubber, combined with the 3.8-mm lugs used by Hoka, performs really well.

As shown in the picture, there's some exposed foam to reduce weight, yet it's extremely durable, and we have no concerns about it.

The lugs are short as expected, making them suitable for buffed trails or gravel roads. This shoe won't excel in technical, twisted terrain, but Hoka has alternatives for that, like the Zinal 2.

A notable disappointment with the shoe is its absence of reflective elements. Considering that the Challenger is designed for all-day wear, the likelihood of using it at night isn't exactly rare, right?

With 6.1 mm of padding, Hoka made the right call by using just one slab of foam at an average thickness.

Less than that might have been too performance-oriented and potentially uncomfortable, while more could have risked adding too much weight to a shoe that already gained an ounce over the standard version.

The tongue of the Challenger 7 ATR is gusseted and fully attached to the sides, a must-have feature in any trail shoe but even more crucial in a Gore-Tex-equipped shoe where full protection from water is the goal.

The heel features a finger-loop tab, which appears to serve more as a style element than a functional one.

The Challenger 7 GTX features a standard insole that's easy to remove and replace if needed. Thanks to the shoe's standard dimensions, fitting third-party insoles is 100% hassle-free.
