Purchased from SteP. I've run about 5 kilometers in them. The Nike Streakfly is Nike's lightest racing shoe ever. It's designed for the speed needed in races from 1 mile to 5K and 10K. The sleek, low-profile design features refined details. It feels so natural you'll forget you're wearing it, enhancing the connection with the road and helping you achieve your personal best.
