The North Face Ultra Fastpack IV FutureLight Boots Light Grey Red Women

The North Face Ultra Fastpack IV FutureLight boots are much better than previous versions. It features the innovative waterproof and breathable FutureLight technology. Thanks to the nano-threaded membrane, the fabric offers exceptional breathability so you can benefit from a waterproof walking shoe without getting hot or sweaty, whatever the weather. But it has more details that make it extremely comfortable. 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 like support where you need it but no extra weight and bulk where you don't then these are the hiking boots for you.

The FutureLight technology developed by The North Face is a revolution in waterproof membranes. It is the first time that air permeability is applied as a characteristic of waterproof membranes, unlike conventional membranes, it contains a nanostructure that allows air to circulate through the fabric, improving ventilation and breathability without affecting resistance or waterproofing. This nano fibre structure has made it possible to create a much lighter and more breathable membrane to date. An ultra-lightweight fabric that protects against the elements in the most extreme environments without sacrificing comfort.
