A perfect grip between the sole and your board whithout any feeling lost of what is happening under your feet.
An unbeatable braking power at high speeds without rebound at low speed.
A sole that doesn’t melt accumulating material behind the areas of maximum presure against the ground but wear away on a uniform way without creating irregular supporting surfaces under your feet.
And THEY LAST!!! … at least twice than any other available sole … and they will do it longer than your shoes.
