With a forged construction, you get a high level of stability and comfort without sacrificing any of the performance you need on the court. It is made with an engineered mesh upper that provides support while still allowing air to flow through, which helps keep your feet cool in warmer conditions. The JPX 921 has an injection-molded sole that gives you maximum traction and support when it matters most.
