This great looking shoe is ideal for the person who likes to mix things up a bit and do some trail running as well as using the shoe for light hikes - a great alternative to taking heavier boots on the trip. They're definitely flexible and tough enough for both types of activities. A waterproof and breathable Goretex membrane keeps feet nice and dry when in wet conditions or crossing the odd stream and embedded cables inside the mesh upper provide lightweight mid foot support. The North Face Cradle Technology provides a stable platform for more aligned stride patterns and the Vibram XS Trek out sole gives durable multi terrain traction. For flexing, bending and connection to changing terrain, there is also a fore foot Snake Plate which enables the foot to do what its physiologically designed to do whilst providing rigidity when and where its required. There is a lot going on with this shoe to make sure you run fast and stay comfortable when out and about exploring.
