Shop the Sustainable Athleta Collection Olympian Allyson Felix Calls "Amazing"

The Crunch Colorblock 7/8 Tight in SuperSonic ($98) aren't just fun and cute; they perform well, too. The high waist doesn't slip or roll down, even during sprints, and the tights are lightweight and breathable for even the sweatiest workouts. I love the Navy/Billard Teal color combo (pictured), but it also comes in Black/Antique Burgundy and Antique Burgundy/Dogwood Mauve.
