The type of terrain the shoe performs best on. Our trail running and hiking shoes fall into one of three categories: moderate terrain, all terrain or technical terrain.

The level of cushioning in a shoe will determine how it feels when your foot lands

Low cushioning: Built for speed. A direct, low-to-ground feel for agility and a lightweight ride.

Mid cushioning: The perfect balance. A mix of softer landings and reactive take-offs for versatile comfort.

Max cushioning: Next-level plushness. Ultimate shock absorption for a super-soft, easy sensation.

Heel to toe drop is the difference in height between the heel and the forefoot. In a shoe with a drop of 7 mm, your heel will sit 7 mm higher than your forefoot. Shoes with a lower drop tend to place more load on the ankles and are generally better for midfoot and forefoot strikers. Shoes with a higher drop tend to place more load on the knees and hips and generally better for heel strikers.
