adidas adizero Boston 12

With brand new recycled EnergyRods 2.0 sandwiched between Lightstrike 2.0 and Lightstrike Pro foams, expect even more power as you transition from heel to toe with the new Boston 12. Because it sits deeper into the heel, you get an even softer feel on step in and heel strike. The upper features adidas Slinglaunch heel system, a design that focuses on providing enhanced heel lockdown, while the extremely lightweight mesh upper features both support and breathable zones. A Continental rubber outsole offers lightweight performance in any weather conditions. By adapting to each runner's foot strike, it provides a smoother and more flexible ride, letting nothing get between you and your best performance.
