Salomon Speedcross 6 Trail Running Shoes Review
The Salomon Speedcross 6 shoes provide excellent traction and stability on the steep, slick, and technical.
September 25th, 2024
Home > Gear Reviews > Footwear
The Salomon Speedcross is consistently one of our favorite trail running shoes, as it offers some of the best traction of any trail shoe available. The Speedcross 6 is a wildly popular shoe — on and off the Treeline Review team — as it has proven to be dependable, durable, comfortable, and excellent on steep and rugged trails.
After testing these shoes over hundreds of miles on mountain trails, muddy hills, gravel, grass, and dusty paths, we can attest to why these shoes have a loyal following. With a wider base and increased stability in this model, and with its ever-impressive traction, the Salomon Speedcross 6 is the best trail shoe we've tested for muddy and snowy conditions. In fact, it earned Best Trail Running Shoe for Traction in our Best Men’s Trail Running Shoes guide and has garnered a lot of praise from our women’s testers in our Best Women’s Trail Running Shoes guide.

Our Verdict
The Salomon Speedcross 6 shines on rocky, steep, muddy, technical terrain. While it's not the best for everyone for everyday conditions, especially runs that crossover to pavement, this shoe is designed for rough trails and is an impressive workhorse for fall, spring, and even some winter running.
We tested the men's and women's models on mountain trails in Arizona, Colorado, California, and Nevada, and in the Bay Area in the winter, spring, and summer. These shoes do their best work on steep terrain, easily navigating loose dirt and allowing for agile movement while racing down trail.
The Salomon Speedcross 6 is one of the best shoes for dependable traction. They may be overkill on flatter trails and aren’t well-suited for the roads, but the lugs aren’t so beefed up that it’s too much for the occasional flat trail runs or paved sections. If you're primarily running rugged trails, the Salomon Speedcross 6 is probably the shoe for you.

Updates in the newest version
The updates to the Speedcross 6 are small, which is a good thing as the Speedcross 5 was already a fan favorite. The upper was revamped and includes adjustments to the lacing slits for a more comfortable fit and less pressure from the laces.
Minor changes to the outsole supposedly expel mud faster and grip surfaces better. We didn’t notice a big difference, but we already found traction and grip to be good qualities of the previous version.
Features
Outsole/Traction
The tread has deep lugs made of Salomon’s proprietary sticky Contragrip TA rubber. The 5mm lugs on these shoes are some of the deepest of any shoe we tested, which is why they’re so great for muddy and rugged trails.The deep lugs might be more than necessary on hard-packed dirt, but they also don’t feel like they negatively affect the traction. Our women’s tester rarely runs in trail shoes with big lugs, and found the Salomon Speedcross 6 nearly as comfortable as her trusty Hoka Speedgoats on less-technical trails.
As mentioned many times already (because it’s truly impressive!), the pronounced lugs provide phenomenal traction on steep, slippery technical terrain. With such incredible traction, our testers even feel secure running in the snow in these shoes without adding traction or spikes.
The Salomon Speedcross 6 has 5mm lugs and a grippy Contragrip TA rubber outsole for excellent traction on steep and slick surfaces.
Stability
The wide base and durable outsole, midsole, and upper construction of the Salomon Speedcross 6 provides excellent stability.
One tester for our review of the Speedcross 5, which is nearly identical to the 6, was particularly pleased with the stability after she wore this shoe on a mountain excursion that included a steep, rocky, and technical descent with about 4 inches of fresh snow on top of slick dirt and rock. She ran confidently, found secure footing, and could keep a good pace due to the traction and stability of this shoe.
The standout features of the Salomon Speedcross 6 are its outstanding traction, grip, and stability on steep, muddy, rocky, and slick surfaces.
Midsole/Cushion
The Salomon Speedcross 6 is a moderately-cushioned shoe. The midsole is constructed with EnergyCell+, which provides a balance of energy return along with cushioning and durability.
Upper
The uppers are welded and hug the foot comfortably. They feel durable while maintaining breathability. The upper on the Salomon Speedcross 6 also have slight updates to the lacing system.
The Salomon Speedcross 6 fits comfortably though can run a bit narrow. Wide sizes are also available, so we recommend trying those if you have wider feet.
Fit and Sizing
The Speedcross is snug where you want it (the heel cup), roomy where you want it (the toe box), and has a wide base for increased stability. The improved lacing system prevents there from being too much pressure on the top of the midfoot.
However, the Speedcross 6, like many Salomon shoes, fits pretty narrow compared to many trail runners on the market. We tested the men's and women's standard width. Our wide-footed men's tester says they feel comfortable over 6-8 miles, but anything longer can be uncomfortable. Our women’s tester has average-to-narrow feet and was comfortable the whole run.
These shoes also come in wide sizing, which we love, so we recommend that option for runners with wider feet.
Related: read our review of the La Sportiva Jackal II for comparison (which doesn’t just run narrow, but runs small).
Rock plate
The rock plate provides added protection running on rocky trails, offering some of the highest protection of any trail running shoe we’ve tested.
Lacing
As with all Salomon shoes, the Speedcross 6 uses the Quicklace single-pull lacing system, which allows you to simply pull a cord and tuck it into a pocket.
The Quicklace single-pull system means you don’t have to tie your shoes. Simply pull the cord as tight as you’d like, then tuck it into the pocket on the top of the tongue.
Warmth
While the Speedcross 6 is not an insulated shoe, the Speedcross 6 GTX (Gore-Tex version) is also available for added warmth and waterproof protection. We did not test this model, but if waterproofness and warmth are a priority, and you’re willing to sacrifice breathability, this could be a good option for you.
Drop
The Speedcross has the highest drop of all the trail running shoes we've tested (10mm), which can feel different for those not used to a high drop. This was designed for going uphill, and another reason it may not be best for flat runs (especially if you’re not accustomed to high-drop shoes).
If you have a consistent mid-foot strike and usually run in shoes with a 4mm drop or less, heel striking in these shoes may feel strange and uncomfortable, and may require a longer break-in period.
Weight
Finally…the Speedcross 6 is one of the heaviest trail running shoes we've tested. They weigh 9.2 oz per shoe in women's and 10.5 oz in men's. This weight is the price you pay for such excellent stability and deep lugs, which is why we recommend this shoe for folks primarily running on steep, technical, rocky, or muddy surfaces.
The bottom line
This shoe specializes in traction. We don't think it is the best for everyone for most conditions, but for people who run more technical and steep trails, or in winter conditions, the Speedcross 6 are top tier.
Our testers picked this shoe for its specialized use in slippery technical terrain and steep descents, especially in the snow. If that’s your running style, the Speedcross is an excellent choice.

The Scarpa Spin Ultras won our Best Trail Running Shoes with Traction in our Best Women’s Trail Running Shoe guide due to its performance on rocky, technical terrain. The reliable grip and ankle support make this a true mountain shoe that handles rough conditions well. They’re also a little lighter than the Salomon Speedcross 6, so if weight is a concern you may like these better.

Like the Salomon Speedcross, the Salomon Sense Ride has been a tried-and-true trail running shoe for Treeline Review testers for years. They offer excellent cushioning and traction over a variety of terrains, from technical mountain trails to rolling, smooth trails. This makes them a little less specialized than the Speedcross and thus a little more versatile.
The Sense Ride won Best Affordable Trail Shoe in our Best Men’s Trail Running Shoes guide, and Best Trail Running Shoe for Narrow Feet in our Best Women’s Trail Running Shoe guide.
This shoe also has less heel-to-toe drop than the Salomon Speedcross 6, which could be an easier transition for folks who aren’t accustomed to high-drop shoes.

How we tested
After our men’s tester put in well over 150,000’ of vertical and over 440 miles gain in a pair, and our women’s tester ran them around the less-technical trails of the Colorado foothills. Our testers put the Speedcross 6s through a variety of terrains and conditions. We ran on trails in Arizona, Colorado, California, Michigan, and Nevada. We ran on dry dusty trails, mucky wet trails, and even in a few inches of snow. Basically, we put these shoes through nearly every condition we could to get a full picture of their capabilities.
We tested the Salomon Speedcross 6 on as many trail surfaces and conditions as possible. Here, one of the authors stands on a peak in the Colorado Front Range.
