WATERPROOFWaterproof fabric provides an impenetrable moisture barrier for guaranteed dryness.STABLEHeel-positioning technology ensures stability on uneven terrain.If you're the kind of hiker that tackles rocky, steep, uneven terrain with pace the Hedgehog Fastpack II Shoes are for you. They're lighter than our classic Hedgehogs, but are still packed with technology to support, cushion and stabilise your journey through rugged terrain. The soles are zonally fine-tuned with Cradle™: the toe area gives added stiffness over technical rock; the midsole is packed with shock-absorbing XtraFoam™ for support when carrying heavy loads; and the heel shape is optimised for comfort. The OrthoLite® insoles maintain their cushioning power over the long term and the durable Vibram® XS Trek outer soles deliver the optimal balance of traction and durability without adding unnecessary weight or bulk. On top of all this, the synthetic nubuck upper is waterproof and the mesh is abrasion resistant, ideal for rocky and gravelly terrain. Basically, the Hedgehog Fastpack II Shoes are incredibly versatile, able to handle wet and muddy as well as dry and stony terrain.
