Under Armour releases the Spine RPM. The running shoe is comprised of a responsive inner core, revolutionary UA Micro G® foam inside for flexibility and support, and an ultra-lightweight UA Spine Cage on the sole of the shoe that keeps the foot locked in place, ensuring the athlete a smooth transition from heel to toe.
The UA Spine RPM’s most distinguishing visual element is the technology-loaded and seamlessly constructed UA Spine Cage, which features a cored-out chassis and the removal of all unnecessary material, resulting in one of Under Armour’s lightest, most flexible running shoes available, weighing 9.7 oz.
The shoe is inspired by the human spine and features an articulated outsole that is shaped to mimic the gentle curvature of the spine.
