Salomon Aero Glide 4 GRVL Review

On my second run after a 5-week hiatus, I clocked my fastest 5K of the year on flat pea gravel trails. It was most definitely the shoes. The evidence is anecdotal, but I consistently found my pace was faster than perceived while running in the Salomon Aero Glide 4 GRVL shoes.

In a bit of a sample mix-up, I first ran in the road shoe version, the Salomon Aero Glide 4, which immediately impressed me with its speed and cushioned support. When I switched to the gravel version, the Salomon Aero Glide 4 GRVL, the feeling wasn’t too far off. In fact, through testing runs on mildly bumpy terrain, these shoes only continued to impress me.

In short: If your training runs include a mix of pavement, gravel, or singletrack, these versatile max-cushioned gravel shoes work for everything from long runs to fartleks.

Salomon Aero Glide 4 GRVL Review

Road Ride Everywhere

I love the versatility of gravel shoes, from the first few iterations of the HOKA Challenger to the more recent Craft Xplor Pro, my favorite wet-surface shoe over the winter.

There are gravel shoes that offer more trail prowess, with features like a wider heel, firmer EVA foam, or a tackier rubber for off-road traction. Yet those more trail-ready gravel shoes feel a little too tready or too heavy for mostly road running, though comfortable enough to get to trails from paved surfaces.

The Aero Glide 4 GRVL takes a “just enough” approach to traction, with 2.5mm multi-directional tread on its ContaGrip outsole, and that’s all you need if you’re leaning toward more road-feel on light gravel. The shoes have a toe bumper and a fairly tough upper mesh material for minimal (not dismissive) trail protection.

When I say these shoes have a road-like feel, it’s true on all the hard surfaces I tested them on: Roads, sidewalks, pea gravel, and hard-packed paths. Transitioning between surfaces was barely noticeable. The Aero Glide 4 GRVL feels like I could run on the road full-time.

The Aero Glide 4 GRVL is well-cushioned and feels more stable than many other gravel shoes, yet has just enough grippy tread and a secure fit to run confidently on hard-packed trails.

It doesn’t have the same protective build as many gravel shoes, and thus keeps the weight down to just 20 ounces per pair. That’s only an ounce more than their roadie cousins. This is in part due to the lightweight foam cushioning and the minimalist take on trail tread. (Gravel shoes don’t use rock plates.)

Speed With Confidence

When I say I was often surprised at my pace while running on gravel, I was running nearly 30 seconds faster than I do on sidewalks along the same testing route. As max-cushioned trainers with a 41mm heel stack, the Aero Glide 4 GRVL proved stable and fast on less challenging terrain.

Here is where the gravel-specific ContaGrip outsole made a difference. This “bike-tire” approach to tread is pretty standard on gravel shoes, just executed well here.

The sole deploys 2.5mm chevron lugs around the edge of the shoe and a shallower section of hexagonal tread under the forefoot, which really bit down on both pavement and loose dirt. There are two thin channels through the foam at the forefoot, which give way to a large, deep recessed section under the heel. (None of which left me with gravel stuck in the tread when I got home.)

Don’t Get Too Technical

I was on the lookout for the height and cushioning to get wobbly while changing directions or hitting steep sections, but I never had issues. The shoes proved stable on some uneven trail sections that were beyond the gravel parameters of the shoe’s design.

I finally found the limitations of the Aero Glide 4 GRVL when I took on more technical trails, both rocky and deeply rutted trails. The shoes don’t offer the luggy reassurance on loose ground or great grip on roots. (In contrast, long lugs can catch on roots and feel noisy on flat terrain.) The real issue is stability on “real” trails, which makes sense considering the Aero Glide 4 GRVL skews to less technical terrain and gravel.

Overall, the shoe performs great while running at full stride on flats and when you have to let the terrain dictate your footing.

The Fit

I have issues with my heel and ankle locking into a lot of shoes. I didn’t slip around in the heel of the Aero Glide 4 GRVL, but I wasn’t locked in either. However, the overall fit was very secure thanks to the EndoFit sleeve around my midfoot. The sleeve wrapped around the top of my foot down to the first metatarsal.

Note: The combination of the internal EndoFit sleeve and a more durable 3D mesh upper means the middle of the shoe felt noticeably warmer during 90-degree runs.

During my first two runs, I felt a slight bump under a toe that fortunately went away as I broke them in. Otherwise, the shoe fit great throughout. The toe box is roomy enough for my wide-ish feet, though perhaps not wide enough to be a selling point for the brand.

I’ve used Salomon’s QuickLace system before, but for whatever reason, this was the first time it really hit me as a set-and-forget solution to dialing the fit. I tend to cinch laces tight to start a run, and loosen them if my feet warm up and swell.

On long warmer runs, the system made it easy to loosen things just enough. The lace buckle also tucks away into a mesh pocket above the tongue to keep it from bouncing around or catching on things.

Great Foam

I especially loved the foam in the heel. It was protective and cushioned braking steps on downhills and helped soften heel strikes when my steps were off due to uneven terrain or just sloppy form. When I accelerated into sprints, Salomon’s “Reverse Camber” rocker geometry helped propel me forward as I dug in. In other words, this shoe nailed the combo of protective cushioning with speedy rebound.

This is what Salomon calls an adaptive ride credited to its OptiFoam2 midsole, which it also uses (though differently) in its Aero Glide 4 road shoe.

Who Is It For?

Gravel skeptics who swear road shoes work just as well on pea gravel and dirt trails should try the subtle difference of the low-tread yet grippy Aero Glide 4 GRVL shoe. Gravel enthusiasts looking for a more minimal take on tread and protection will like the low profile of this shoe. Everyone will appreciate the speed of this max cushioned trainer.

If I could only pick one shoe for training runs beyond roads, travel runs, and even some semi-technical trails, this is it.

These shoes are priced on the high end of everyday trainers, yet cheaper than most super trainers. If you like Salomon shoes, add these gravel shoes to your quiver. They are lightweight and peppy without the price and gimmick of carbon.

As for long-term durability, I didn’t hit the 100-mile mark for a more informed prediction. The 3D-mesh upper shouldn’t be an issue, and the OptiFoam2 foam is well-regarded and often lasts 400 miles. Beyond any build failure, the outsole tread should be the first thing to go. It barely wore down during my testing, so guessing how many miles it lasts is more a matter of running form and the surfaces run on.

Lastly, let me just say the snakeskin design of these shoes is a welcome break from the loud colors and patterns of so many others out there. And even the white material doesn’t show dirt the way darker colors do. If you’ve owned a white vehicle, you might get it.
