This is one I hope is never discontinued! I'm on my 4th pair now and will most likely go through many more... Very tough shoe that offers great response and feel for the trail. The sticky sole is perfect for approach and I even use it for low 5th rock climbing. Have used these at Leadville and many other races and long runs and they work very very well on all types of terrain (especially trail), dry fairly quickly after stream crossings, and are comfortable to wear for 24+ hours...
