Ready for takeoff? Under Armour designed the Grade School Charged Scramjet 3 Boy's Running Shoe drawing their inspiration from jets. That's why the Scramjet 3 Running Shoe is all about spring to give you forward thrust and propulsion when you're running. It's all in the magic of the midsole, which features Under Armour's Charged Cushioning (constructed from compression molded foam), that gives it such impressive response and durability. The midsole's advantage works not only to propel you but also provides you with excellent protection from impacts on each footfall. For further protection, this Shoe supplies a counter to the external heel, giving you better stability. Still, the HeroFlex Sole offers you great flexibility so your foot has total freedom of motion. It also boasts rubber pods under the heel and forefoot where they help you most. Working in concert with an anti-odor, plush sockliner, these Running Shoes truly give you all-day comfort that makes it feel like you're running on air...like a jet plane. Fly in your own pair of Grade School Charged Scramjet 3 Running Shoes for boys.
