Cushioning Level
Cushioning level, or stack height, refers to how much shoe is between your foot and the ground. For this category, we reference the amount of cushioning below the forefoot as the heel height will be equal to or greater than the forefoot height.
Learn more about stack heights and how we measure them.-
Barefoot
0-13mm. The Shoe generally does not have a midsole and feels like there is no cushioning. This shoe is all about feeling the ground underfoot.
-
Minimal
14-18mm. The shoe has a thin midsole that allows for a natural running experience. Racing shoes and minimalist shoes are common here. These shoes offer a feeling of being connected to the road or trail.
-
Low
19-23mm. The shoe has a slightly cushioned feel and may feature added cushioning technologies. Performance training shoes and some trail shoes are common here. These offer protection during footstrike but prioritize a lightweight, grounded experience.
-
Medium
24-28mm. These shoes have a stack height that fall near the middle of the spectrum.The shoes in this category are verstaile and great for all types of runs and distances.
-
High
29-34mm. The shoe has a thick midsole and ample cushioning. These shoes are highly protective and absorb more impact than the body.
-
Maximal
35mm plus. The shoe has an extremely thick midsole and extra cushioning. The focus is on protection and soft foam underfoot with hardly any ground feel.
Stability Level
-
Neutral
Neutral shoes support the foot through a normal range of arch collapse and generally do not have a built-in technology to correct movement.
-
Stable
Stability shoes are a great option for those who overpronate or need added support. These shoes help to limit the inward rolling motion of the ankle while running or walking and assist in guiding the foot straight through the gait cycle.

What's in a name? The Salomon S/Lab Pulsar 4, like its cosmic namesake, is famous for rapid motion and high-speed energy. Developed with elite pro Rémi Bonnet, this fourth chapter of the iconic trail racing shoe is more robust and multi-capable than before.
