展开In its sixth iteration, the Challenger ATR 6 exceeds its reputation for versatility. As its name suggests, this versatile off-road shoe defies convention, with lightness in the mountains and smoothness on the asphalt, thanks to the structure of the midsole and the construction of the sole. Dynamically designed to offer versatile traction, its distinctive outsole has a zoned construction to optimize grip and weight. The outsole of the Challenger ATR 6 has been developed with wide, closely spaced studs that provide smooth transitions from one surface to another.
