The Under Armour Charged Rogue Twist Ice is a shoe that offers maximum shock absorption while being extremely lightweight so you can run longer and farther. It features a specially designed knit upper that hugs the foot for a secure fit and a stable external heel counter for added stability that keeps the back of the foot locked in place. Additionally, it has an antimicrobial Ortholite insole that molds to the foot. The Charged Cushioning technology uses compressed molded foam for even greater responsiveness and durability of the shoe, offering maximum shock absorption and energy return.
