Inspired by the most dynamic motion system ever created, the Under Armour Spine RPM does what other running shoes can’t. It gives you a responsive, lightweight, flexible cushioning system that also supports every move you make. So you can run farther, train harder and become more powerful. Lightweight seamless construction provides structural support at mid and forefoot and comfort. Ultra lightweight heel counter locks down the heel. Full-length Micro G™ internal midsole offers an ultra-responsive, lightweight ride. Spine chassis delivers the ultimate in lightweight structure. Full-length, molded 4D foam sockliner and collar lining are built to mold/conform to your foot. Carbon rubber covers the heel impact zone. Solid rubber outsole gives full ground contact and traction without adding weight.
