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. Unlike EVA, the tubes resist compression-set and won’t alter with
temperature extremes— maintaining their cushioning and support functionality.
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.
