I'm replacing my Reebok Red & Black ZigTech's with the Green & Black Zigtech after about a year of fairly moderate use. I wear them to my full time job as a resort bellman, to the gym and to the playground with my son. These things took a beating and honestly the sole is still in relatively good condition. Sadly it was the fabric on the top that had given way at the crease where your toes bend by the knuckle of your foot. Other than that theses shoes were stylish, light, durable and very function-able... not to mention the compliments and questions you get about them constantly. My favorite, as they look odd to some people was "Do they hurt?" No silly people no, they feel awesome.
