The K-Swiss Express Light 3 HB is a lightweight tennis shoe designed for on-court performance and a great level of comfort. As the updated model of its successful predecessor, the upper features DuraWrap Flex, a newly designed molded RPU cage that provides flexible support and drag protection. On the inside, a well-padded ankle collar provides comfort and stability while a die-cut foam sock liner adds responsive cushioning underfoot. The Express Light 3 has HB outsole featuring deeply grooved herringbone patterns for exceptional traction on clay court surfaces.
