The UA Charge RC packs seven game-changing innovations into fast running shoes that weigh in at less than 10 ounces. A two-piece upper encourages your foot to flex like it does naturally. Snug, UA compression wraps your forefoot muscles in a squeeze that maximizes their strength and slows fatigue. UA HeatGear® fabric wicks away sweat to keep your feet dry, cool, and ultra-comfortable. Micro G® foam and a carbon fiber spring plate add a bounce to each step, converting downward heel-strike energy into forward energy. Inside, our 4D Foam® sockliner literally molds to your foot for a slip-free fit. We added more of it around the collar, so you won't even feel this shoe around your ankle. Be light on your feet. And be quick about it. With the fast, innovation-packed UA Charge RC.
