With its then-new midsole material that brought outstanding performance, the original Energy Boost created excitement. As good as the midsole material was, the importance of geometry and fit can’t be overemphasized, and the Energy Boost 2 focuses on dialing these in.
The upper retains the stretchy fabric of the original, but adjustments in tailoring and additional structure in the saddle allow a more accommodating fit to the snugness, while effectively conforming to more feet. In some cases, sizing up is recommended, and the only way to know what works for you is to try it on. The midsole is unchanged, making the Boost a lightweight Neutral shoe that protects but also has a pretty snappy feel. The outersole features full-length Continental carbon rubber for more durability. With its cushy and responsive ride, the Boost continues to attract fans.
Testers: “Really like the feel of these shoes, the combination of the toespring and the energy return of the Boost when running. No matter how far I run in them, my feet still feel good.”
