The Gel-Challenger is ASICS' line designed for the baseline player: the one who builds points from the back of the court, changes direction dozens of times per game, and needs a shoe that can withstand the lateral wear this involves. Version 15 is one of the most comfortable options in its court-stability range.
WINGWALL technology is positioned along the side of the midsole to improve stability during side-to-side movements, while the DYNALACING system adjusts the fit to keep the foot securely in place. In white with Gunmetal details—a dark metallic gray—it preserves the classic tennis look without appearing flat.
It is one of the most well-balanced tennis shoes in terms of comfort and durability. At Next Step, we offer it 100% new and authentic, with 14 calendar days for returns from receipt and fast shipping to Spain and throughout Europe.
White with metallic gray is the quintessential court uniform and works just as well with shorts and a polo as it does off the club grounds. Discover more models in our ASICS collection at Next Step.
