First developed for runners trying to break the two-hour marathon barrier, Nike Zoom technology has taken the brand’s running innovation to a new level, with many styles incorporating at least some Zoom elements. Up top, the Flyknit upper of this edition comes in an eye-catching Obsidian-based color, with hits of Moon Particle, white, Volt and Indigo providing dimension. The Nike Zoom Fly ‘Obsidian’ sneaker uses Zoom’s combination of Nike React foam in the midsole and a carbon fiber plate to help increase speed.
