Salomon Speedcross 6 - Women's Review

With a more comfortable, redesigned upper, the improved Salomon Speedcross 6 is a shoe we love for mountain running. It has grippy lugs that extend up to the toe cap and a heel cup that is plush and narrow. Featuring a one-pull lacing system and a measured heel-to-toe drop of 13 mm, the Speedcross 6 is one of the most rugged shoes in our lineup.

Comfort and Fit

The Speedcross 6 didn't earn the highest marks for this category because it is not for everyone. Runners whose feet fit comfortably in this shoe will adore its snug sensation, but the fit is certainly not universal.

Even more so than on previous versions, the Speedcross 6 feels narrow and has a narrow midfoot. Our lead tester has average-width feet and found it fantastic amid sloppy terrain. We hesitate to recommend the Speedcross to runners who have wide feet or who just prefer a bit more space to let their feet squirm. Despite its narrower-than-average midfoot, the toe box provides adequate space for toes to splay, flex, and adjust while running.

The plush tongue and heel collar are wonderfully comfortable. We love that Salomon kept some cushion and didn't strip down these comfortable and protective elements in this version. The Speedcross features a Quicklace, one-pull lace system, which has historically been a style we criticize. To be clear, we still don't love it, but the well-cushioned tongue prevents the thin laces from digging into the top of your foot. The lace pocket has been redesigned, but it is still not particularly functional. The back of the padded heel collar rises a bit high on the Achilles and might not suit the anatomies of all runners' ankles, but we love how the collar dips down to accommodate protruding ankle bones.

Our main gripe with the Speedcross 6 is that it doesn't breathe. This is not surprising considering how well the upper deflects sand and fine particles. We never had any serious troubles with our feet heating up, but we also did most testing in the early mornings and late evenings in coastal California. This will be my go-to winter trail running shoe because of its capabilities, but we would have to pause before recommending the Speedcross to runners who reside in steamier climates.

Stability

With recent updates, the Speedcross has become noticeably more stable. The forefoot is a bit more spacious, with a slightly larger landing platform. The heel cup cradles the ankle in such a way as to keep it from slipping or sliding around, even if that is what you are doing across a snowfield.

The stability of the Speedcross 6 is good, but not great. It is better than it used to be, but we hesitate to recommend this trail runner to anyone with a history of ankle-rolling injuries. The 13 mm drop makes it less stable than a shoe with a lower heel-to-toe differential and a slightly wider support base. The side walls are high and inflexible, which helps aid in this stability. We definitely noticed a difference running in these shoes when compared to some of our more stable choices, but we also found that the benefits of the Speedcross far outweighed its average stability.

Traction

The Speedcross 6 excels in traction, with aggressive, widely spaced lugs and ContraGrip rubber that bite into the trail, even on soft surfaces, giving the shoe a “baby crampon” appearance.

While the tall, well-cushioned heel dampens underfoot sensation, it reduces overall sensitivity, slightly dampening the confidence-building agility that this outsole can offer. This combination of comfort, protection, and partial sensitivity makes the Speedcross feel secure in most mucky conditions, though the lack of full sensitivity can feel slightly less secure on slick, moving rocks. When it comes to the lugs specifically, he main drawback is that they wear down quickly on paved surfaces, so it's best kept strictly for trail use.

Foot Protection

The Speedcross 6 has a firm toe bumper, one of the more notable protective features we look for in a trail running shoe. The bumper even has a few sticky lugs on the underside, which adds extra protection and helps give this shoe its rugged appearance.

The Speedcross 6 is advertised as a 10 mm drop shoe; however, when we measured this aspect, we got 13 mm. When assessing the protective prowess of a trail running shoe, we often consider how plush the midsole is since this is a major line of defense when it comes to protecting the soles of your feet. The heel stack height of this shoe sits at 33 mm, which is quite high, with the toe measuring in at 20 mm — significantly lower. It is worth noting that Salomon claims the stack height is 32 mm at the heel and 22 mm at the toe. However, these measurements aren't standardized across the industry, which may explain why our standard in-house findings differ.

If you are a heel striker, you will love the plush heel of the Speedcross. If you are a midfoot striker, you will likely notice that the more flexible design provides far less protection from sharp rocks than many cushier trail runners. Much like its predecessor, this version of the Speedcross has a welded overlay bumper that runs the width of the shoe. We love this for the protection it provides, not just from wet terrain but also from rogue sticks, thorns, and anything else you might encounter at ground level on the trail.

Because of how tight the upper weaving is, we never had any trouble with sand getting in through the exterior of this shoe. The synthetic material is designed to keep sand and particulate matter out, and its performance shows this. When we purposefully tried to kick sand up into the heel of the shoe, we succeeded — but only barely. Because the heel cup is snug and well-padded, there isn't a ton of space for sand to infiltrate in that location.

The Speedcross 6 does a great job of deflecting the elements when needed, but it certainly isn't waterproof. This trail running shoe is a showstopper for wet, sloppy weather, so as you can imagine, our feet got wet while we tested. If a muddy run with some raindrops is in your future, you can count on the Speedcross to keep you upright and dry. Though expected because of its textile, we were pretty stoked about how quickly the upper nylon mesh dried after getting saturated.

Weight

The Speedcross 6 weighs in slightly better than the average trail shoe, but not by much. Each women's size 6.5 shoe is 8.54 ounces, which is about what we would expect from a trail running shoe.

The kicker with the Speedcross is that it is so well-featured that of course it weighs more. Just looking at the lugs and ankle padding gives you an idea about why this shoe weighs more. That said, the weight is well-distributed, which makes it feel lighter while running. If you want an ultralight shoe, this might not be it. But if you want a shoe that can handle the grittiest of trail adventures, make peace with the extra ounce and utilize all that the Speedcross has to offer.

Should You Buy the Salomon Speedcross 6?

The Speedcross 6 is a reliable steed that shows up to work. It is a fantastic shoe if your runs are littered with scree, snow, puddles, and steep, unending climbs. If you are a new trail runner seeking a shoe to suit your needs, this one might be too much. And if your runs occasionally take you down warm, paved paths, we recommend steering clear of the Speedcross. But if dirty mountainous terrain is your jam, this is a shoe to seriously consider.
