The Thunder Blade Z has been redesigned from the shaft to the sole and is the optimal model for comfort and lightness. The tension-free shaft 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. The air cushions and lightness from the molded midsole and outsole design offer additional comfort. The wide outsole ensures stability. A removable 5 mm insole and the U4icX Strobe Panel provide a softer initial comfort. The non-marking rubber outsole ensures strong grip on the court.
