Nike Running has just unveiled a slew of brand new Zoom Air models for Spring/Summer 2014. Consisting of four models, the collection includes the new Air Zoom Pegasus 31, Air Zoom Structure 18, Air Zoom Elite 7 and the Air Zoom Streak 5. The latest Pegasus is a neutral shoe designed for daily running and training and features a Zoom Air bag in the heel, a 10mm drop for a more natural gait, and a midfoot saddle for extra structure and support. The Structure is a stability shoe designed for over-pronators and uses Nike’s Dynamic Fit technology with a triple density midsole to stabilize the foot and minimize rolling. For those who prefer a lighter training shoe, the Elite features a Zoom Air bag in the forefoot and a minimal drop of just 8mm to keep runners closer to the ground. Finally, there is the Streak, a shoe built for race days and designed to put you in position to win with a lightweight upper and a midsole system incorporating both forefoot Zoom Air and Phylon for enhanced responsiveness. The Elite and Structure will be available in August and October, respectively, but you can get the Streak and Pegasus now at Nike.
