Salomon Aero Glide 4 Gravel Review: A Cushioned Daily Trainer with Off-Road Scope

Introduction

The Salomon Aero Glide 4 Gravel is the all-terrain version of the Salomon Aero Glide 4, and after plenty of miles in it as an everyday mixed-surface trainer, it has earned a firm recommendation. Salomon’s previous Aero Glide generation was highly rated, and this version builds on that with the same midsole concept plus a more substantial outsole and a more protective upper with a quick lace system.

It costs £145 or $160, the same price as the road version. Weight is 277 g or 9.7 oz in a UK 8.5 or US 9, which is genuinely light for a shoe with a big midsole stack and a generous outsole.

Who This Shoe Is For

This is a shoe for runners who spend most of their time on runnable surfaces but regularly drift off the tarmac: canal towpaths, park paths, forest tracks that are not excessively muddy, and roads that get sloppy in winter. It is not a technical trail shoe, and it is not trying to be. Instead, it is what many would call an all-terrain daily trainer, comfortable and protective for easy runs, long runs, and steady work while carrying a bit more grip and durability than a standard road shoe.

If you are a runner who loops from road onto riverside paths, or who wants a cushioned trainer with the option to detour onto gravel without swapping shoes, this fits that brief almost perfectly.

Design and Outsole

The upper is a fairly pliable engineered mesh with lots of overlays and a significant toe bumper for protection on all-terrain runs. Padding around the heel is generous, yet the heel design is more flexible than the road version’s. The quick lace system lets you tie the laces one-handed, and while it is a matter of taste, it worked without problems during testing. On-foot feel is among the most natural of the Salomon shoes tested, with good midfoot lockdown and some room for toe splay.

The midsole uses Optivibe Squared, a supercritical TPU foam, in a 41 mm heel and 33 mm forefoot stack for an 8 mm drop. Salomon’s reverse camber rocker, inspired by its ski heritage, tips you forward gently without feeling aggressive. The outsole is Salomon’s Contagrip gravel rubber with chevron-shaped lugs around 2.5 mm deep and extensive coverage, including a sizeable cutout in the middle that will collect some mud. The thick outsole handles all-terrain use well and, importantly, does not detract from road performance at all.

One design gripe: getting the shoes on is a wrestle. There is no heel pull, and with high insteps the lower quick laces can be hard to loosen in the midfoot. Once on, though, the fit is secure and comfortable.

Fit and Sizing

The consensus from testing is that this is a true-to-size shoe. One tester who took a half size down found it cramped, with rubbing around the outside of the little toe on longer runs, and wished they had stuck to their normal size. Go with your usual size and you should be fine.

For very long ultra-style days where feet swell, some may want extra volume up front, but for typical daily training and a 20k long run, the standard sizing worked well with good lengthwise clearance.

Run Performance and Ride Feel

Testing covered just under 90 km of daily training: easy runs, easy-to-steady progression runs, and a 20k long run, across road, towpaths, park paths, and forest trails. The headline is simple: this is an excellent cushioned shoe that competes not just with all-terrain rivals but with the best cushioned road shoes on the market.

The cushioning is high but the shoe never feels big or bulky. The foam balances comfort with a pleasant firmness, so you get protection at the heel without sinking in, and the rocker moves you smoothly from heel to toe with a little pop off the toes. Legs felt very good after long runs. It is not a flat-out speed shoe, but it goes through the gears nicely and keeps you moving at easy paces.

On grip, the outsole is nicely judged. In deep mud the lugs are not deep enough to bite, but outside of that it copes well, and on wet road it grips especially well, which is not always the case with Contagrip. It rolls through as smoothly as a normal road running shoe, and the extra coverage only becomes an advantage when you leave the tarmac.

Durability and Value

At £145 or $160, this feels like strong value for a shoe that can absorb a big chunk of your yearly mileage across multiple surfaces. The thicker outsole should translate to good durability, and the ride quality does not suffer for it. The Aero Glide 4 Gravel is slightly heavier than the Aero Blaze 3 Gravel, but you get more midsole protection in exchange, which pays off on longer runs.

How It Compares

Against the Hoka Challenger 8, the Salomon is a bit firmer but very much in the same comfortable road-to-trail territory. The Brooks Ghost Trail has firmer foam and a flatter, less bouncy and smooth ride. The Adidas Evo SL ATR has a much more minimal outsole geared to winter road running, is lighter and less cushioned, and does not tackle trails as well; the Salomon is the more comfortable daily trainer of the two. Among the tested winterized gravel shoes, including the On Cloud Surfer Trail, Merrell Pro Morph, and Mount to Coast H1, this was preferred to almost everything else in the mix.

Compared with top cushioned road shoes like the Nike Vomero Plus and the Kiprun Kipride Max, those two are bouncier and have more spring, but the Aero Glide 4 Gravel is actually lighter than them and adds outsole versatility without losing anything on the road. It is a realistic contender even for runnable multi-surface ultras, where forest trails alternate with tarmac and extra protection deep into long miles matters. For something like the Marathon des Sables, it was called a strong contender, if only getting them on and off were easier.

Buying Advice

Buy the Aero Glide 4 Gravel if you want one cushioned trainer for mixed surfaces, or even if you run almost entirely on road but want the option to detour off it. Go true to size, expect a firm shove to get your foot in, and do not expect deep-mud traction. Everything else here is very well judged.

Conclusion

The Salomon Aero Glide 4 Gravel is an excellent cushioned running shoe with the bonus of a better outsole for light trails, horrible wet roads, and added durability. It handles everything from easy cruising to marathon-pace work, grips well in wet conditions, and undercuts many rivals on weight. For mixed-surface runners, this is one of the best options in its category right now.
