Salomon S/Lab Pulsar 4

Salomon S/Lab Pulsar 4 review: what runners say

Fit

Narrow through the midfoot, almost sock-like thanks to a fully gusseted tongue. Entry is difficult; the toe box widens slightly compared to previous generations, but runners with wide feet or high metatarsals will feel pressure across the knuckles.

Feel

Direct and fairly firm ride, with a touch of softness at the heel and limited energy return compared to competing trail super shoes. The wide platform delivers control and stability even on uneven terrain.

Durability

The Believe in the Run reviewer notes visible midsole foam abrasions already present after the test period; another source considers the upper better constructed than the Pulsar 3 and estimates 'a couple of race seasons.' Cautious consensus: midsole longevity worth monitoring.

Best for

Shoe for fast runners on technical and rolling trail, distances from 10K to 50K. Also suitable for quick ultramarathoners (documented top-10 Western States finish); less recommended for heavier runners or those seeking maximum cushioning on very long efforts.

Weak points

Difficult to get on, with fit that is not accommodating for high-volume or wide feet. Shallow lugs and low-grip rubber prove inadequate on slippery mud. Midsole vulnerable to abrasion from rocky terrain.
