Salomon's S-Lab shoes are iconic in the world of trail running and racing, and the Men's S-Lab Fellcross 2 Trail Running Shoe is one of the newest additions to the family. Lightweight, low to the ground, and capable of producing massive amounts of traction, this shoe is the direct result of design feedback from Salomon's team of elite trail runners. Fans of Salomon shoes will discover that the Fellcross is a little more minimalist than some of its cohorts, but that minimalist comes without sacrificing the protection needed to safely conquer rough, rocky trails. Pin your number to your shorts, slide this shoe on your foot, and claw your way through the pack as you conquer steep climbs and winding descents with the type of confidence that ensures victory. 

  • Anti-debris mesh and water-resistant textile upper with mud guard help you master the trail, even if it's not in perfect condition
  • Fell Running Last is lightweight, minimal, and designed for precise control over foot placement and foot strike
  • Ortholite footbed offers support and cushioning
  • SensiFit is Salomon's unique way of shaping the upper to wrap around your foot for a close and responsive fit
  • Quicklace lacing cinches down and secures the shoe with a simple pull of a drawcord
  • Lightweight Muscle chassis features two layers of EVA in the midsole to reduce the constant impact of running
  • Low 4mm drop (heel-forefoot offset) allows you to transition easily between heel, midfoot, and forefoot striking styles
  • TPU toe cap provides protection against rocks, roots, and other trail hazards
  • Lightweight Mud & Snow Contagrip sole is highly durable, and features chevron-shaped lugs designed specifically to provide superior traction on a wide range of tricky trail surfaces, including mud and snow

Falling Apart!

  • Familiarity:I've used it several times
  • Fit:True to size
  • Height: 5'10"

    Size Purchased: 10

After two weeks the shoes are showing wear badly. Even the sole on the right shoe is peeling away from the heel. I haven't even used the shoes yet, just been wearing them around the office trying to break them in. Not a fan.


1st Impression........

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:True to size

So I literally just got these shoes today. In all honesty, I bought them primarily to run in the snow this winter with something that provides great traction. I had a pair of sneakers w/ decent traction & protective frame but I ruined them in a few Spartan Races. Since, I've tried to find a shoe which not only will provide me with great traction during winter snow runs, but also during trail and mud runs/races. Having purchased a pair of Salomon Anka boots, figured I'd give Salomon a shot. I did some research & came across the SpeedCross 3's & FellCross 2's. Searched stores to try both on, but only found the SpeedCross 3's. Tried them on, & compared them to a pair of XA Pro 3D CS WP's.

While I love mud runs, I'm typically an endurance runner so weight made a swift difference. With the Speedcrosses being approx. 11 ounces vs. the XA's which claim to be 12.35 ounces each, it was a no brainer considering I wouldn't want to fatigue quicker during a run due to additional weight. (Note: I'm a huge fan of Merrell Trail Glove and Ascend shoes as well as NB Minimus, however, again, they don't provide enough traction, nor are they water repellent).

After trying on the Speedcross size 10's, I was sold. I immediately came onto Backcountry and placed my order. I still wasn't sure re: the Fellcross 2's but figured take a shot & buy em too. 2 days later (Backcountry friggin' rocks!) my box arrived and I couldn't wait to test both out. I tried both on in the house. The Speedcross 3's though narrow seemed fine even with a pair of cushioned socks. My gf said they looked tight but with some adjusting they felt fine. Then the Fellcross 2's. Slight difference. The Fellcross 2's felt somewhat narrower and tighter, but was promptly resolved by switching to compression socks. Fit similar to the Merrell Trail Gloves with a narrower forefoot but light and comfy. Decided on a run. 4.1 miles later I was sold. They were great during the run. I just need to try them out in the snow now.


Not holding up to Wasatch conditions..

In short:I own the Speedcross 3 and did R2R2R on them, so I was looking forward to a slightly lighter shoe with less drop from Salomon. Unfortunately, I had to send these back because the lugs on the bottom were ripping off after barely 20 miles of running...

I'll start with saying they when I first tried on these shoes they felt even narrower then my Salomon Speedcross shoes in the nose. Since I prefer the wider toe box of the NB minims shoes I was skeptical at first. But after a 10 mile run I found that it didn't bother me too much and actually kept my feet fairly snug on some demanding downhills. Where the Speedcross had some play and I have a few (minor) blisters, the Fellcross 2s were just perfect.

I would have loved to wear these without socks, but the edge around the heel cup is quite foamy and that doesn't make for a good bare-foot experience so I only wore Patagonia Merino running socks in these, a great pairing. These shoes are compact, light, sturdy and provide a great running feel.

Now for the not so nice part... The profile on the bottom is fairly aggressive (it's the standard Salomon traction pattern) and the v-shaped lugs were ripping off on the rocky trails here in the Wasatch. The rubber on these shoes is exceptionally grippy, and I assume that's perfect for maybe the pacific north west, forest trails with graver and mud, maybe even sleet-slush and snow...but no match for the local rock. The rubber must be very different from the Speedcross3 sole, because they wear, but don't seem to 'rip' off and I've had 200+ miles on those shoes.

So, unfortunately I had to return these shoes and I'm not sure yet what I'll replace them with. I really wanted these to perform, but they are just not durable enough (and I don't need 'race' shoes I guess).

what is the difference between this shoe...

what is the difference between this shoe and the Salomon fellcross, I have that one and love it, but can't find it anymore.

Disclaimor: I don't own either of these shoes, but it is my impression that for this season Salomon split the 'fell' line into two different shoes. This one (the fellcross) is the lightweight hightech racing version, and the fellraiser ( is the more everyday shoe or training, etc. Take a look at the fellraiser, I have heard excellent things about them, and they might be closer to what you are looking for.

I own the S-lab Fellcross 2 but not the fell raiser. I own dozens of Salomon products. My 2cents: s-lab is for high efficiency minimalist runners. The light weight is essential to this line and the minimalistic approach. I love the S-lab fellcross I have put a good 100 miles on them on snow/ice trail runs. Nothing I have ever owned did so well in these difficult conditions. The traction is crazy but may be too aggressive for normal trail conditions but for anything extreme where massive traction counts and you want a minimal fast and super light shoe this is the to go to shoe.


Incredible shoe

I have transitioned from road runner to trail runner. several years ago I switched from full support to Neutral and minimal running shoes (Saucony Kinvara 2-3-4) and have since been without any injuries. In preparation to some mountain races in Austria I ordered several Salomon trail shoes among them the Speedcross 3 and XT 6. Both immediately gave me pain and problems and I generally found them to be "too much" of a shoe for me personally. I returned them to Backcountry (what an awesome organization) and ordered the S-lab shoes Fellcross 2, Slab-Sense Ultra 2 and Sense 3 Ultra Trail running shoes. I live in Indiana and we have had an extreme winter with lots of snow, ice. I have since logged about 40 miles in the S-lab Fellcross 2 on snow and this is the best running experience I have ever had with new shoes. I hit the trails with 4-5 inches of snow on top of ice and the traction and the stability of this shoe is amazing but with a minimalist approach. You feel totally in control 100% of the time even in such difficult conditions. I have since run on somewhat softer snow and also compacted hard snow. No matter what the Fellcross is a sheer miracle. I had no issues or pain like with the heavier shoes from Salomon or others. I also love the fit on this shoe I have a somewhat narrow to medium size foot but the shoe fits like a glove. especially after about 20 miles the shoe fits perfect. I cannot imagine that a shoe in this category could be any better, worth every penny. Salomon S-lab is the best.
