The outsole unit of the Top 12% in is composed of a rubber compound called MaxTrac. This layer covers the entire midsole foam, protecting it from the abrasive nature of outdoor terrains. It has a grippy character that allows it to naturally deliver traction. Many trail shoes from Altra utilize this technology, including the well-known Lone Peak.
Heightened surface adhesion is provided by the TrailClaw, a set of extended gripping lugs that have a skewed construction. These protrusions act like claws that ensure surface stability and control, especially when handling upward and downward traversals.

The midsole unit of the Superior 4.0 is composed of Altra Quantic foam, a full-length foam that provides responsive underfoot performance and impact mitigation. It has a lightweight build that frees the foot from feeling encumbered.
The InnerFlex is a system of grooves in the midsole that encourages natural foot flexibility. Such a mechanism heightens the quality of the step.
Improved impact attenuation and anatomical equilibrium are afforded by the Zero Drop platform. This even heel-to-toe differential also enables the instinctive performance of the foot, accommodating slight biomechanical adjustments to accentuate speed and foot-to-ground steadiness.
A removable StoneGuard layer is placed above the primary cushioning system. It protects the foot from sharp trail debris and rough surfaces.
