Northwave Origin Plus 2 MTB Shoes A seamless unibody construction on the upper of the Origin Plus 2 MTB Shoes creates a comfortable fit thanks to reduced pressure points, making it a perfect shoe for all-day adventures on the trails. Pores across the surface of the upper allow the shoes to remain breathable and vented keeping you cool on even the hottest days. The upper is TPU welded to the sole giving extra strength and minimising potential damage to the key joints in the shoe. A Triple-density Speedlight 3D sole keeps the shoe stiff with a Northwave in-house stiffness rating of 10.0. The Northwave SLW3 dial allows step by step increases in the pressure of the shoe or full release with a single touch so you can keep your pressure dialled across your ride.
