Grade School UA Charged Pursuit 2

Light and flexible is the name of the game here. A lot of mesh for breathability and Charged Cushioning to help protect against impact. Just put them on and run for miles.

• Lightweight mesh upper delivers complete breathability
• Foam padding placed around your ankle collar & under the tongue for an incredibly comfortable fit & feel
• Charged Cushioning midsole is firmer in the heel & softer in the forefoot for support & comfort
• Tire inspired outsole pattern provides ultimate flex & superior traction
