The Lightning Star Z7 Jr has been completely redesigned from the upper to the sole, making it the ideal model for comfort and lightness for young players. The stress-free upper construction, combined with a soft EVA injection and a lightweight outsole, allows you to focus on the moment. The wide outrigger forefoot and TPU stabilizer in the midfoot provide stability in key areas. Benefits include cushioning and low weight thanks to the molded midsole and well-shaped outsole. The wide outrigger sole ensures high stability. The removable 5 mm thick insole and U4icX Strobel board offer a softer entry feel. The non-marking rubber outsole provides good grip on the court.
