Xero Shoes Mesa Summit review

The Xero Shoes Mesa Summit comes perfect for:

• Those seeking a minimalist trail shoe with comfort and versatility for easy trails and daily adventures.
• Anyone who finds barefoot shoes too wide but wants a low-to-the-ground design for gravel roads, forest walks, and light runs.
• Beginners to minimalist footwear looking for a comfortable, value-focused trail shoe with excellent outsole durability.

Runners with wide feet won't find immense room for toe splay in the Mesa Summit. If you're in this group or simply want a very wide toebox, check out the Xero Shoes Speed Force II instead for gravel or roads, or the Xero Shoes Scrambler Low if you mainly hit the trails.

We also think those who want a super-flexible, low-stack shoe with decent impact protection won't find enough shock absorption here. Instead, check out the New Balance Minimus Trail.

Most brands aim for high shock absorption when developing a shoe, but that's the opposite of what Xero Shoes is trying to deliver. As a minimalist brand, we weren't surprised to find just 35 SA in the heel and 38 SA in the forefoot, the lowest values we've recorded in quite some time in our lab.

The energy return isn't particularly impressive at 53.9%, but that's not a major concern for a minimalist shoe, as most of the bounce has to come from your tendons due to the limited amount of midsole foam.

One result that's absolutely key to confirming this is a true minimalist trail shoe is the stack height. Starting with the heel, we have zero complaints, as we measured just 13.6 mm.

That's a very respectable figure for a trail shoe designed to stay as close to the ground as possible while still offering a rugged outsole and some protection for the foot.

During our runs, we consistently felt how little separated our feet from the ground, with plenty of feedback throughout each stride, especially when landing on the forefoot. And again, that's hardly surprising when just 13.3 mm of material separates your feet from the ground.

Xero Shoes designed the Mesa Summit as a zero-drop minimalist shoe, and we verified that claim in our lab. We measured just 0.3 mm of drop, fully confirming the flat, natural geometry of the midsole.

One of the most interesting design features of the Xero Shoes Mesa Summit comes here. To address the issue of rocks and roots digging into the foot with previous minimalist trail shoes, Xero Shoes added a foam-based rock guard that runs from heel to toe.

It's not a traditional rock plate, as that would make the shoe too stiff for a minimalist trail shoe that needs to remain flexible. Instead, Xero Shoes uses a super-firm EVA foam that we measured at 78.6 AC, providing good protection from the terrain while maintaining the shoe's flexible nature. And yes, that's the midsole of this shoe!

Running and hiking in the shoe makes it very clear that the midsole has no rocker and simply follows the natural shape of the foot. However, we still had to take our lab mug shot, and it confirmed that the midsole is indeed almost completely flat!

A friendly reminder that's always worth making is that a minimalist shoe doesn't necessarily belong in the barefoot category, and that's exactly the case with the Mesa Summit.

In our first measurement, we found a 92.6 mm width, making it clear that Xero Shoes designed the Mesa Summit with a more snug fit.

The toebox is slightly more generous at 74.4 mm, but it's still well below what we usually see in foot-shaped shoes, which tend to measure around 80 mm.

That said, we think most runners will prefer this more secure design, especially when the terrain gets twisty and requires extra foot control.

Despite its low-profile appearance, the Mesa Summit offers adequate toebox height, and we never felt any pressure against our toes during testing.

Back in the lab, we measured 28.8 mm, putting it slightly above the current average.

We secured the Xero Shoes Mesa Summit to our traction machine, which follows the SATRA TM144 friction standard, and measured a coefficient of 0.55.

That's not a particularly impressive result, although it should be enough for most situations where a shoe with shallow lugs like this one will be used. However, we think there's definitely room for improvement here.

We mentioned the shallow lugs, and here they are, measuring just 3.1 mm deep. We're not against this design because, for a minimalist trail shoe, deeper lugs would feel extremely awkward, so we think this is the right call.

However, keep in mind the usual limitations of shallow lugs, as they're much better suited to gravel roads, parks, and other easy terrain.

We liked the full-length rubber coverage on the outsole, which is ideal for durability and protection. As for the lugs, there's not much to say because the design is very simple, with chevron-shaped lugs throughout and a few smaller ones around the heel.

One of the most important boxes for any minimalist shoe to tick is flexibility, and the Xero Shoes Mesa Summit certainly delivers.

In our test, we needed just 4.1N of force to bend it 30 degrees, confirming an extremely flexible ride despite the rugged outsole.

During our adventures with the Xero Shoes Mesa Summit, we never felt like it was a lightweight shoe. That may seem counterintuitive, but it's actually quite common with minimalist shoes.

At 9.8 oz (279g), we really wished Xero Shoes had managed to keep the weight lower.

The Mesa Summit keeps your feet much closer to the ground than most running shoes, creating a naturally stable feel, especially for runners with a neutral stride.

Don't expect the shoe to provide much support, but it also stays out of the way and doesn't interfere with your natural movement.

The shoe is slightly more rigid than some runners might expect, but that's the trade-off for its trail-ready outsole. We needed 9.9 Nm of torque to twist it in both directions.

The heel counter also stays out of the way, following the shoe's minimalist approach by leaving most of the support to your foot. In our test, we rated it just 2/5.

Going close to the ground has the advantage of reducing the need for a wide midsole to maintain stability, and the Mesa Summit takes full advantage of that.

At 107.2 mm wide, the platform provides enough stability without sacrificing the excellent agility that comes with its streamlined design.

With its zero-drop geometry and focus on promoting a natural midfoot or forefoot strike, it makes sense for the heel to stay close to your foot's natural width. Therefore, while 81.0 mm may seem narrow to some runners, it fits exactly what we'd expect from a shoe like this.

It's important for any shoe heading into the mountains to have an abrasion-resistant upper, and this one delivers. A 4/5 score is a strong result, and we also found that Xero Shoes added generous overlays around the toe cap for extra protection.

We were disappointed to see the heel area get destroyed during our Dremel test, earning it a 1 out of 5, our lowest possible score.

Those worried about early outsole wear can put those fears to rest, as our Dremel test showed that just 0.6 mm of rubber was worn away, proving that the lugs are built to last.

The outsole measures 1.7 mm thick, which seems like solid protection for a minimalist shoe. In fact, we're a bit surprised Xero Shoes managed to keep it this flexible with such a design.

The insole measures 4.1 mm thick and provides most of the underfoot comfort, as it's clearly softer than the midsole foam.

A very nice touch from Xero Shoes is the ventilated insole, which allows more airflow than the denser insoles found in most shoes. That's certainly not something we usually see at this price point!

The EVA foam is so firm that even after 20 minutes in the freezer, it felt almost exactly the same, like a brick. And our lab results explain why: it changed by just 6%!

It would've been nice to find some reflective elements on the Mesa Summit, but unfortunately, Xero left them out.

Xero designed the lacing system with a mix of punched eyelets and four lace loops to help reduce pressure across the foot, and we found that it works well.

The tongue feels comfortable, which isn't surprising given its generous 7.8 mm of padding. However, that extra material also helps explain why the shoe weighs more than we expected.

A nice touch from Xero Shoes is the semi-gusseted tongue, which improves the fit while helping keep debris from entering the toebox.

The heel features a sturdy finger-loop tab that feels nearly impossible to rip off, while also making the shoe much easier to put on.

The Xero Shoes Mesa Summit comes at a reasonable price. It doesn't offer flashy features like a Vibram outsole, but it also avoids the premium price tag. In our view, that's a fair deal from Xero.
