Now in their fourth iteration, the Ultra Fastpack Shoes just keep getting better. This mark IV version features a breathable-waterpoof FUTURELIGHT™ membrane. Springy, OrthoLite® X35™ Hybrid™ footbeds are cushioning, but also responsive and along with the FastFoam™ midsoles maximise energy return for a more efficient trek. The Ultra Fastpacks are engineered specifically for moving quickly over tough trails: the lug design is optimised for undulating, rocky terrain; the Vibram® Megagrip™ does exactly what the name suggests – grips on all surfaces, both wet and muddy and dry and loose – and the protective toe caps and heel overlays help prevent stubbed toes and bruised heels. If you don’t to be weighed down by overly robust and ridged hiking shoes, then the Ultra Fastpacks are for you.
