As HEAD's lightest shoe, the Sprint Pro 3.5 is made for players who are looking for more agility on the indoor court. The mesh material makes the shoe lightweight and extremely breathable while the sock construction takes care of the out-of-the-box comfort you crave. And on top, the new Delta Straps and TPU heel counter keep your foot in place during tough rallies. These shoes are a narrow fit around the toe, therefore we would advise sizing up if you are between sizes.
