  • This shoe is expensive.
  • According to some runners, this shoe had a narrow forefoot.
  • Some runners felt that due to the minimal ground contact, stability feature is limited.
  • It lacks the underfoot protection needed while running on rocky surfaces.

Bottom line

The S-Lab Fellcross 3 is a reliable Salomon running shoe because of its durable, comfortable and flexible attributes. However, this shoe is not ideal for extremely rough terrain because it does not have the necessary cushioning and support. A few were not happy with the shoe's narrow fit and limited underfoot protection, but overall, the Fellcross 3 has proven to be a successful update.

73 / 100 based on 8 expert reviews

  • 70 / 100 | The Ginger Runner | | Level 5 expert

    It is a bad-ass trail shoe; one that can get you through all the nastiest trail you can think of.

  • 89 / 100 | Caveman Clarke | Level 3 expert

    With its narrow fell last and secure feel, it may not be the best option for anyone with very wide feet or a need for extreme comfort.

  • 68 / 100 | Gear Institute | | Level 3 expert

    The large outsole lugs live up to expectations, but the narrow forefoot and small ground contact area limit stability on technical and off-camber trail.

  • 50 / 100 | Outdoor Kinetics | Level 3 expert

    The only issue I have had with durability on the Fellcross 3 is that a couple of lugs have had sections shear-off after running fast on sharp rocks.

  • 82 / 100 | Men's Fitness | Level 2 expert

    Designed specifically for fell running (that’s mountain running) in foul winter weather, this mud- and snow-shredding shoe cuts weight with a fused—rather than sewn—construction.

    While I liked being close to the ground, on really uneven terrain my outside ankle bones (lateral malleolus) took a bit of a beating.

  • The 3rd version of the extremely popular Fellcross series is Salomon’s action to previous issues regarding upper durability. Salomon utilizes in this version a denser and tighter weave mesh to enhance the upper’s long lasting-performance. Although this upper is not water repellant, it does an effective job of keeping off light drizzle, dust, and powdery snow.
  • Salomon puts a premium on a seamless upper this time around. Welded and bonded overlays dominate the upper as opposed to the stitched versions of the prior model. The update provides excellent support and structure while the seamless upper lessens the dangers of irritation or hot spots.
  • The Fellcross 3 also improves the foothold of runners on the trail by doing two things. One, the last has been changed to a slightly narrower model to provide a secure hold on uneven terrain. Second, there is a continuous substantial overlay that stretches from the forefoot to the heel to really secure the foot, especially the heel.
  • The addition of the Endofit Sockliner, which is made of plush fabric, is another update that enhances the fit and comfort of this shoe.

Generally, the fit and sizing of this shoe resemble that of the prior version, except that it is a bit narrow in the forefoot due to the new last. Salomon markets the Fellcross 3 as having standard fit and length in men’s sizes. Runners with regular widths or narrow measurements should be able to get their most comfortable feeling in this shoe. Available sizes are from 4 to 15.


Same as in the popular Salomon Sense Ride 2, it uses the Contagrip outsole that is designed to tackle mud and snow with ease. Salomon uses aggressive lugs that are generously spaced apart. While the structure and configuration of the Chevron lugs deliver superior bite on mud and soft trail, the spacing of the lugs also allows the shoe to shed off mud naturally.


Two midsole layers are utilized in this area. A lightweight EVA foam called LT Muscle by Salomon is the first layer for impact-absorption. The second part is a compression molded EVA that gives a bit of cushioning. It is not too soft, but just gives the right amount of cushioning with really good responsiveness.


The denser and more durable mesh fights off debris, light drizzle, and a little snow. Keeping off the elements is further enhanced by the gusseted tongue. For protection against bruising, a lightweight TPU material or a Rubber Toe Cap heads the forefoot. Salomon improves the step-in comfort and fit of the Fellcross 3 by introducing the Endofit Sockliner. Speed laces made of Kevlar make cinching easy and convenient.
