The Hierro has always intended to be used for long trail runs but it is a great shoe for anyone who enjoys a little extra cushioning. The newest version uses the same cushioned Fresh Foam X midsole and Vibram Megagrip® outsole as the V5 to deliver durable traction on both wet and dry terrain.  What has changed from the V5 is the upper (in this case a Goretex upper to keep your feet dry), providing a slightly snugger fit and improved durability by adding TPU threads to high wear areas.  A slightly extended outsole in the heel area provides increased surface area for downhill running.
