The consensus on the Salomon S-Lab Ultra 3

The Salomon S-Lab Ultra 3 has garnered acclaim for its performance on technical trails, offering a blend of stability, protection, and traction that is hard to match. Its sticky lugs and Energy Save midsole provide a ride that is both protective and nimble, making it a top choice for rocky and complex terrains. Runners seeking a shoe that excels in technical conditions will find the S-Lab Ultra 3 to be a worthy investment, despite its premium price point. While the shoe's durability is debated, with some users experiencing wear after intense encounters with sharp objects, others report longevity exceeding 600 miles. The shoe's precise fit and breathable upper contribute to its comfort, although some may find the collar tight and the lace pocket cumbersome. Overall, the S-Lab Ultra 3 is recommended for experienced trail runners looking for a reliable and versatile shoe that can handle a variety of trail conditions.

Comparable Shoes

The Salomon Speedcross 6 is a good alternative for those looking for a shoe with epic traction and a beefier overall design. While it is less expensive than the S/Lab Ultra 3, it offers similar performance features, making it a viable option for budget-conscious runners.

For runners seeking a more affordable option, the Brooks Divide 4 may be worth considering. Although it comes at a lower price point, it does not match the S/Lab Ultra 3 in terms of performance features, particularly in challenging trail conditions.

The HOKA Torrent 3 is favored for slightly less technical terrain, offering a more relaxed fit for the foot. It is a suitable choice for runners who desire a bit more roominess in the upper without sacrificing a technical fit.

The Saucony Peregrine 13 appeals to those seeking a lighter-weight shoe that still provides a snappy feel. It is an excellent choice for runners who want to maintain speed without the harshness associated with race-level shoes.

In Depth


The Salomon S-Lab Ultra 3 features an updated Matryx mesh upper that enhances breathability and comfort. This design choice makes the shoe suitable for warm weather and long runs where ventilation is crucial. The upper's construction provides a snug fit that adapts to the foot, offering a secure feel even on uneven terrain. However, some runners may find the collar tight, and the lace pocket design has been noted as difficult to use.


The midsole of the S-Lab Ultra 3 is crafted with Energy Save technology, which offers a responsive and protective ride. This feature is particularly beneficial for long-distance runs where underfoot protection is essential. The midsole's design does not include a rock plate, but it effectively disperses the impact from sharp objects, ensuring a comfortable run without compromising ground feel.


The shoe's Contagrip outsole is praised for its durable and sticky nature, providing trustworthy traction on a variety of surfaces, including muddy and rocky trails. The measured lug depth of 3.5mm ensures a firm grip, making the S-Lab Ultra 3 a reliable choice for runners who encounter diverse trail conditions.


The S-Lab Ultra 3 offers a neutral fit with a regular-width toe box that accommodates different foot shapes. The shoe's fit is described as specific, and it is recommended that runners try on the shoe to ensure a comfortable fit. The precise fit contributes to the shoe's overall stability and comfort during runs.


Comfort in the S-Lab Ultra 3 is achieved through a combination of a breathable upper, responsive cushioning, and a secure fit. The shoe's design minimizes extraneous movement, even on technical descents, providing a comfortable experience for the runner. However, the tight collar may require runners to wear higher socks to avoid discomfort.


The cushioning in the S-Lab Ultra 3 strikes a balance between sensitivity and protection. With 27mm of total stack in the heel and 19mm in the forefoot, the shoe offers enough cushioning to protect against rough terrain while maintaining a close-to-ground feel that allows runners to sense the trail beneath them.


The Matryx mesh upper of the S-Lab Ultra 3 ensures that the shoe remains well ventilated, making it an excellent choice for running in warmer conditions. The breathable material helps to keep the feet cool and dry, reducing the risk of discomfort during extended runs.


Stability is a standout feature of the S-Lab Ultra 3, with a design that provides a low-to-the-ground feel and excellent lateral support. The shoe's broader base and specific fit contribute to even impact distribution, allowing runners to confidently navigate technical terrain.


While the S-Lab Ultra 3's durability has been questioned due to the upper's susceptibility to damage from sharp rocks, many users report a lifespan of over 600 miles. The shoe's build quality suggests that with proper care, it can withstand the rigors of trail running for a considerable amount of time.


The grip of the S-Lab Ultra 3 is a highlight, with the Contagrip outsole providing secure traction on various trail conditions. The lugs are designed to handle everything from muddy paths to rocky inclines, ensuring a safe and stable run.


The S-Lab Ultra 3 offers a moderate level of flexibility, allowing for natural foot movement while maintaining enough structure to support the runner on uneven terrain. The shoe's balance between flexibility and support is well-suited for trail running.

Who should buy the Salomon S-Lab Ultra 3?

The Salomon S-Lab Ultra 3 is best suited for experienced trail runners who frequently encounter technical and challenging terrains. It is ideal for those who value a shoe that provides a secure fit, responsive cushioning, and exceptional grip. Runners with a preference for a breathable and protective design will appreciate the features of the S-Lab Ultra 3, making it a strong contender for long-distance races and training sessions.

Who should not buy the Salomon S-Lab Ultra 3?

Runners who prefer a softer, more forgiving cushioning may not find the Salomon S-Lab Ultra 3 to their liking, as the midsole is on the firmer side. Those with wider feet might struggle with the shoe's regular-width toe box, and individuals looking for a budget-friendly option might be deterred by the shoe's higher price point. For those seeking a more roomy fit or a softer ride, alternatives like the HOKA Torrent 3 or the Saucony Peregrine 13 might be more suitable.
