Props to Puma for trying something different like this tech-forward hightop that is the Metropolis Collection SX850. If the name of the sneaker sounds tech-heavy, its because it is. A full air bag caps off the sneaker, and the toe-box is perforated just enough so your feet will be able to breathe in the heart of summer. Check select locations that carry Puma like UNDFTD in the next few weeks.
