salomon aero glide 4 grvl review

In my second race after a 5 week hiatus, I completed my fastest 5km of the year On flat pea gravel paths. It was definitely the shoes. The evidence is anecdotal, but when running in the Salomon Aero Glide 4 GRVL shoes I consistently found that my pace was faster than anticipated.

In a little sample mixing, I ran in the road shoe version for the first time salomon aero glide 4Which immediately impressed me with its speed and cushioned support. When I switched to the gravel version, the Salomon Aero Glide 4 GRVL, that feeling wasn’t too far off. In fact, during testing on mild rough terrain, these shoes continued to impress me.

In short: If your training runs involve 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 trip everywhere

I love the versatility of gravel shoes, from the first few iterations of the HOKA Challenger to the recent Craft Explore Pro, which is my favorite wet-surface shoe in the winter.

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

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 just what you need if you’re leaning toward a more road-feel on light gravel. The shoes feature a toe bumper and a fairly tough upper mesh material for minimal (non-dissolving) trail protection.

When I say these shoes have a road feel, that’s true on all the hard surfaces I tested them on: roads, sidewalks, pea gravel, and rough trails. The transition between surfaces was barely noticeable. The Aero Glide 4 GRVL feels like something 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 it still has enough grip and a secure fit to confidently walk hard-packed trails.

It does not have the same protective structure as many gravel shoes, and thus the weight remains at only 20 ounces per pair. That’s just one ounce more than their roadie cousin. This is partly due to the lightweight foam cushioning and minimalist approach to trail tread. (Gravel shoes do not use rock plates.)

speed with confidence

When I say that I was often surprised by my speed when running on gravel, I was running about 30 seconds faster than on pavements on the same test route. As max-cushioned trainers with a 41mm heel stack, the Aero Glide 4 GRVL proved stable and nimble on less challenging terrain.

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

The sole deploys 2.5mm chevron lugs around the edge of the shoe and a shallow section of hexagonal tread under the forefoot, which really bites into both pavement and loose dirt. There are two thin channels through the foam in the forefoot, which give way to a large, deeply recessed section under the heel. (None of these caused any gravel to get stuck in my walk when I got home.)

Don’t be too technical

I was looking for height and cushioning so that I wouldn’t wobble when changing direction or hitting steep sections, but I never had any problems. The shoes proved stable on some uneven trail sections that were beyond the gravel parameters of the shoe’s design.

I eventually discovered the limits of the Aero Glide 4 GRVL when I tackled more technical trails, both rocky and deeply rutted. The shoes do not assure comfort on loose ground or provide good grip on roots. (Conversely, longer 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 is meant for less technical terrain and gravel.

Overall, the shoe performs very well when running full length on flats and when you have to allow the terrain to dictate your feet.

fit

My heels and ankles suffer from being trapped in too many shoes. I didn’t slip into the heel of the Aero Glide 4 GRVL, but I also didn’t lock out. However, the overall fit was very secure thanks to the Endofit sleeve around my midfoot. The sleeve wrapped from the top of my foot down to the first metatarsal.

Note: The combination of an internal Endofit sleeve and more durable 3D mesh in the upper means the middle of the shoe feels noticeably warm during 90-degree runs.

During my first two runs, I felt a slight lump under the toe which fortunately went away as I broke it in. Otherwise, the shoe fit perfectly. The toe box is roomy enough for my wide 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 struck me as a set-and-forget solution to dialing in a fit. I tie the laces tightly to start the race and loosen them if my feet get hot and swollen.

On long hot runs, the system made it easy to loosen things up considerably. The lace buckle is also hidden in a mesh pocket above the tongue to keep it from bouncing around or catching on things.

great foam

I especially liked the foam in the heel. These were protective and cushioned braking steps on slopes and helped soften the heel strike when my steps were slipping due to uneven terrain or simply sloped form. When I accelerated into a sprint, Salomon’s “reverse camber” rocker geometry helped me propel myself forward while digging in. In other words, this shoe accomplished the combo of protective cushioning with quick rebound.

It’s what Salomon calls an adaptive ride thanks to its OptiFoam2 midsole, which it also uses (though in a different way) in its Aero Glide 4 road shoe.

who is it for?

Gravel skeptics, who swear that road shoes work equally well on pea gravel and dirt trails, should try out this subtle variation of the less-treaded but entertaining Aero Glide 4 GRVL Shoe. Gravel enthusiasts looking for minimal tread and protection will love the low profile of this shoe. Everyone will appreciate the speed of this maximum padded trainer.

If I could only choose one shoe for training off roads, travel races, and even some semi-technical trails, it would be this.

These shoes cost more than everyday trainers, yet are cheaper than most super trainers. If you love Salomon shoes, add these gravel shoes to your quiver. They are light and energetic without the gimmicks of price and carbon.

As far as long-term durability is concerned, I couldn’t reach the 100-mile mark for a more informed prediction. The 3D-mesh upper shouldn’t be a problem, and the OptiFoam2 foam is well-regarded and often lasts up to 400 miles. Beyond any manufacturing failure, the outsole tread should be the first thing to go. It barely scuffed during my testing, so estimating how many miles it lasts is a matter of form and the surfaces the tread runs on.

Lastly, I just want to say that the snakeskin design of these shoes is a welcome break from the funky colors and patterns of many other shoes. And even white materials don’t show dirt as well as darker colors. If you have a white vehicle then you can get it.
