Give it your best shot, this one won't break. HEAD's SPRINT SF is the answer to the conflict of abrasion protection versus lightweight comfort. The solution comes in the form of SuperFabric® material which is incredibly durable and yet super light, flexible, and quick-drying. Featuring many of our latest HEAD technologies, the shoe is also out-of-the-box comfortable thanks to its special elastic sock construction. The SPRINT SF is also picking up the distinctive flip design of the GRAVITY racquet series, which means the laces, soles, and sockliner are color-reversed, which will make people look at your feet first.
