The Thunder Blade Z has been redesigned from the upper to the sole and is the optimal model for comfort and lightness. The tension-free upper construction combined with a soft EVA injection and a lightweight outsole allows you to focus on the moment. The wide forefoot and the TPU stabilizer in the midfoot area provide stability in key areas. Air cushioning and lightness are achieved through the molded midsole and the design of the outsole. The wide outsole ensures stability. A removable 5 mm insole and U4icX Strobe Panel offer softer initial comfort. Non-marking rubber outsole for strong grip on the court.
