We make the Wildfire 2's precise-fitting upper from robust, recycled mesh and reinforce it with a network of Kevlar cables that wraps the foot for flexibility, fit and enhanced torsional stability and heel support. What's more, the Wildfire 2 switches quickly and easily from hiking mode to climbing mode using the SALEWA Switchfit adjustment system. The result: better edging and smearing and overall security on technical terrain. Moreover, the Multi Fit Footbed Plus (MFF+) provides a customizable fit, for a more narrow or wider comfort.
