New for 2025, The Stack series has our signature fit with enhanced features. Built on our original custom last, the Stack Series delivers the wide and deep toe box and curved heel fit players rely on for locked-in stability and all-day toe comfort. The new lightweight, scuff-resistant KPU material in the upper is built to withstand wear and tear while maximizing airflow ventilation, keeping your feet cool through every match.
Featuring the same herringbone tread as our Smash series, this high-abrasion outsole delivers exceptional traction on any playing surface—whether you’re competing on silica grit-treated outdoor courts or smooth indoor tile and parquet floors.
A removable polyurethane insole and shock-absorbing EVA midsole provide long-lasting comfort, while the exterior heel stabilizer and torsion control shank work together to reinforce lateral stability—giving you the support and confidence to move freely.
