The Vibram Megagrip outsole is a standout here, especially on damp tracks and technical sections where confidence underfoot keeps your pace steady. The dual density midsole also makes this a good choice for runners transitioning from road to trail, as it offers protection without feeling unstable.

---------------
Cushioning
-
The material that absorbs the impact against the ground. The more cushioning utilised, the softer a shoe will feel underfoot.
Neutral Support
-
Normal sized Arches.
-
During push off there is an even distribution from the front of the foot.
-
The foot lands on the outside of the heel, then rolls inward to absorb the shock and support body weight.
Drop
-
The difference from the heel of the shoe to the forefoot.
-
Shoes with a higher heel drop tend to be preferred by runners that land heel-first.
-
Shoes with a lower heel drop are often favoured by forefoot or midfoot strikers.
