The adidas Terrex Free Hiker GTX 'Core Black' features a sneakerboot silhouette and straight-forward black and white colorway. Its Primeknit upper has been reinforced with a GORE-TEX membrane for added defense in wet and inclement conditions. Stabilizing overlays and plastic components help reinforce the shoe, which rides atop white Boost cushioning. In true Terrex fashion, the design is finished with aggressive Continental rubber tread.
