Inspired by the "big energy" of Bryce Harper, the Under Armour Harper 10 RM is designed to keep you going strong through every inning. This 10th-anniversary edition features a light, breathable synthetic upper that is built for maximum durability. The full-length EVA midsole provides consistent underfoot cushioning, while the newly designed rubber molded outsole ensures comfortable traction on all field surfaces, from dirt to grass.
