Perri Konecky, POPSUGAR senior editor of trending and viral features, likes her Nike Air Zoom Pegasus 38 ($120) sneakers because of the comfort they bring (they're cushioned for running). "I wear them on the treadmill and for long walks and jogs outdoors," she said. "They're a tiny bit wider than typical Nike shoes, so my toes don't feel as constrained, but they are breathable enough to nurture each of my strides."
