Technology : Trailspring
Trailspring® Technology : Connected by supportive struts, horizontal tubes are strategically placed in the lateral and medial sides of the heel to optimize cushioning and reduce over-pronation on impact. The tubes resist compression-set and won’t alter with temperature extremes— maintaining their cushioning and support ability.
Lateral Cushioning

The tube’s suspension bars run parallel to the ground, contracting and expanding on impact for optimum cushioning on heel strike.
Medial Support

The tube’s suspension bars are vertically tuned to reduce over-pronation by offsetting directional force.
