I love the Chaco Z/1. This is my third pair. Each pair has lasted me 4 years in the past. I wear them all the time when I am not at work. They have decent arch support and can handle ANY terrain. My last pair made it to the bottom of the Grand Canyon and back, kayaking the ocean, hiking, rafting and mountain biking all over the west. I bought them June 2004 and retired them August 2008. I would have sent them in for a re-tread, but the straps were starting to deteriorate. I could go on for hours. They are worth every penny I spend on them.
