The Zone XT 'Black' training shoe is designed to enhance performance, and its straightforward color scheme only adds to its appeal. The black mesh upper not only provides a sleek look but also offers lightweight support with the inclusion of no-sew overlays. To add a touch of contrast, the PUMA formstrip on the lateral quarter panel is outlined in white. Moreover, the inclusion of an external heel clip ensures stability, while the midsole is crafted using a combination of IGNITE foam and NRGY beads. This innovative hybrid system not only guarantees exceptional cushioning but also delivers superior energy return.
