From the smooth versatility of the Aero Glide 4 GRVL to the mud-ready precision of the Speedcross 6 GORE-TEX, Salomon delivers two trail shoes built for different kinds of runners and terrain.
Salomon Aero Glide 4 GRVL: A Cushioned Daily Trainer for Gravel Crushing
The Salomon Aero Glide 4 GRVL (for women or men) takes the platform of the standard Aero Glide and adapts it for runners who regularly move between pavement, gravel, park paths and mellow trails. It keeps the same high-stack, rocker-driven ride as the road version, but adds a more protective upper and a more capable outsole for mixed terrain.
Despite the added grip and protection, it still feels surprisingly light for a max-cushioned shoe, weighing 277g / US 9. Stack height comes in at 41mm in the heel and 33mm in the forefoot for an 8mm drop.
The setup is designed to deliver comfort over long miles without sacrificing versatility. Salomon uses an engineered mesh upper with protective overlays and a reinforced toe bumper, while the midsole features OptiFoam supercritical TPU foam paired with the brand’s Reverse Camber rocker geometry. Underneath, a Contagrip outsole with 2.5mm chevron lugs provides traction over messy terrain.
Runners with high insteps may find themselves wrestling with the shoe slightly before it settles comfortably into place. Once on foot, though, it feels natural. The engineered mesh strikes a nice balance between flexibility and structure, giving enough room through the forefoot for everyday running while still locking the foot down well through the midfoot and heel.
Protective & Balanced
The standout feature of the Aero Glide 4 GRVL is how well it balances cushioning with efficiency. There’s a lot of foam underfoot, but the shoe never feels oversized or clumsy. Instead, the combination of the rocker geometry and the moderate-firm midsole creates a roll that keeps transitions quick and easy.
The ride feels highly protective without becoming overly soft or unstable. Easy runs and recovery miles are where the shoe shines most, but it also handles progression runs and faster cruising paces better than many max-cushioned trainers.
The combination of the rocker geometry and the moderately firm midsole creates a smooth rolling sensation that keeps transitions quick and easy.
What makes the shoe especially impressive is how little compromise there is when moving off-road. On pavement, it feels similar to a dedicated road trainer, with the outsole avoiding the overly firm sensation that some hybrid shoes develop.
The outsole isn’t designed for highly technical terrain or deep mud, but that’s clearly not the intention. This is a road-to-trail shoe in the legit sense: ideal for runners whose routes naturally mix surfaces rather than those heading deep into mountain terrain.
Long-Route Specialist
The Aero Glide 4 GRVL feels particularly well-suited to marathon training and long mixed-surface runs where comfort matters just as much as traction.
The shoe compares well against some of the best cushioned road shoes currently available, including the New Balance FuelCell Rebel V5. Salomon manages to combine softness and surface feel more successfully than most. Compared to dedicated road super trainers like the FuelCell Rebel, it may not feel quite as explosive or energetic, but the balance is excellent. The ride stays lively enough for uptempo efforts while remaining comfortable and protective deep into long runs.

Salomon Speedcross 6 GORE-TEX: Built For Mud, Steep Trails & Harsh Conditions
The Salomon Speedcross 6 GORE-TEX (for men or women) is purpose-built for hellacious terrain and conditions. This is not a cushy daily trail cruiser or a road-to-trail hybrid. It’s a highly specialized shoe designed for mud, steep descents, loose surfaces, technical rocks and wet conditions where grip and control matter most.
The GORE-TEX version adds a waterproof membrane ideal for cold-season running, mountain routes and wet/muddy environments. One small tradeoff, however, is breathability. The engineered mesh upper is dense (also very durable) but offers respectable breathability, though it can’t match the porous mesh used in runners built specifically for hot, dry conditions. So this shoe is for cooler/damp conditions, where it excels. And during testing in moderate spring conditions, the shoe was comfortable and never hot.
Salomon’s Sensifit upper remains one of the standout features of the Speedcross. It wraps closely around the foot with a contoured design for an almost second-skin feel. And we found the shoe fits true to size, though, as expected from Salomon, the fit leans narrow. Runners with wide feet may find it restrictive, particularly through the midfoot and forefoot. However, I have reasonably wide feet and did not find the fit restrictive. The Quicklace system provides fast adjustments and a clean, consistent fit, but some runners may still prefer traditional laces for fine-tuning tension.

Aggressive Grip on Tech Terrain
The Speedcross 6 GORE-TEX delivers a firm and grounded ride. Runners looking for highly cushioned, maximalist platform similar to a Hoka may want to look elsewhere. The defining feature of the Speedcross 6 is its outsole. Salomon’s Contagrip rubber is paired with deep 5mm chevron-shaped lugs that bite into mud, loose dirt/rocks and steep trails. The traction is excellent both uphill and downhill, particularly when cornering or moving through rock gardens. Even in wet conditions, the outsole feels dependable. Compared to trail shoes aimed at mixed terrain, the Speedcross feels more razor-focused.
In testing, the grip rivalled hiking footwear and compared favourably against the Saucony Xodus Ultra. The rubber compound feels slightly softer than average, which improves grip but also means the outsole might wear faster on pavement. If you’re accustomed to starting or ending on pavement during your trail runs, you might prefer to avoid too much of it with these runners.
Stability Specialist
One of the biggest surprises with the Speedcross 6 GTX is just how stable it feels, especially for a fairly narrow shoe. The torsional stiffness is high (comparable to some carbon-plated shoes, despite the lack of a plate), helping the shoe stay composed on uneven ground and steep off-camber sections. The heel construction also plays a major role here. The rear of the shoe is notably stiff, which gives the platform a reassuring feel during descents and sharp directional changes. Combined with the flared heel geometry, it creates a landing platform without making the shoe feel bulky.
Firm, Grounded, Built For Control
The shoe also features a fairly aggressive 11 mm heel-to-toe drop, which becomes noticeable on steep descents. Some runners may appreciate the extra heel support, while others may find the geometry limits forefoot flexibility on downhill terrain. That said, the setup works well for the shoe’s intended purpose. The firm platform, stiff heel and aggressive outsole combine to create a controlled and secure ride when terrain (and conditions) are unpredictable.
The combo of grip, stability and a wrapped, performance fit gives the shoe a very distinctive feel that few competitors match. For runners who regularly tackle difficult terrain in any weather, the Speedcross 6 GORE-TEX continues to justify its rep as one of trail running’s most capable specialists. –Ned Morgan
