The Under Armour Charged Rogue Twist Ice is a shoe that offers maximum shock absorption while also being extremely lightweight for running longer and farther. It features a specially designed upper knit that hugs the foot for a secure fit, as well as a stable external cover on the heel for additional 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, providing maximum shock absorption and energy return.
