The flat rubber compound is optimized for grip and durability. It has high-friction to stick to the pedal body and low rebound properties to damp vibrations. The lugs are rounded to resist abrasion.
The tread pattern is designed for traction off the bike. Directionally angled and spaced toe and heel lugs offer traction for hiking up or down steep terrain. The ramped toe provides walkability on steep terrain.
The tread pattern is designed for maximum contact surface and compatibility with the pedal platform. In addition, the lug depth is designed around pin dimensions to absorb the pin body.
