The Under Armour Dynamic Select Training Shoe in Tech Blue is crafted for versatile athletes. Combining the responsive cushioning of a running shoe with the stability and traction of a lifting shoe, it's engineered to support you through every workout - from sprints to squats - without compromise. They are durable, breathable, cushioned, and give you the right support, workout after workout. Featuring a lightweight, super-durable ripstop upper, a molded TPU clip for added lateral support, and a cushioned sockliner that molds to your foot, eliminating slippage and providing ideal underfoot comfort. The Charged Cushioning® midsole absorbs impact and converts it into a responsive burst, while the durable rubber outsole has strategically placed flex grooves for multi-surface traction and flexibility.
