The second FORCE10 component is the TPU cemented scuff cap, providing incredible durability properties over traditional rubber scuff caps, being cemented to the boots ensures there is no stitching to fail.A solid Perspex midsole board provides not only maximum torsion control to the same standards as the worlds best hiking boots, but also giving far better durability when digging. The Denver is 100% waterproof, and includes a high performance Activ-Tex® membrane, great for working in wet conditions. These boots are a true all rounder designed for the toughest terrains.
