Supportive struts and horizontal tubes that optimise heel strike cushioning and reduce over pronation for increased comfort and support.
Trailspring Technology is comprised of connected support struts and horizontal tubes are strategically built into the lateral and medial sides of the heel.
The lateral cushioning consists of suspension bars running parallel to the ground, which contract and expand on impact, providing a shock absorbing cushion for heel strikes.
Meanwhile, the medial support suspension bars run vertically to reduce over pronation while providing stability and support as the foot rolls forward from heel to toe.
Unlike EVA, the tubes used in Trailspring Technology resist compression set and will not alter with temperature extremes while maintaining their cushioning and support.
