A posting system which minimises rear foot movement and controls pronation for more efficient heel strike to toe-off action whilst running.
There are two types of Roll Bars, although both of them are combined with New Balance TS2 technology for the ultimate in stable motion control.
100% coverage Roll Bar utilises TPU posts on both sides of the heel, preventing outward roll of the foot.
The 35% coverage on inside of foot reinforces the side wall, increasing stiffness to prevent the heel from rolling inwards or pronating.
Finally, a composite plate in the heel improves heel strike stability and forward roll for more controlled momentum while running.
