Head has engineered the Head Endure Pro BOA Clay shoes to bridge the gap between their stable and durable Revolt Pros and their speedy and breathable Sprint Pros; delivering a high performance fit and feel that all levels of players can benefit from. Featuring a dual dial BOA system (Li2) on each shoe, that allows you to personalize the fit and tighten or loosen each notch of the dial for the perfect feel. This BOA system also redistributes the pressure on top of the foot so that it hugs and cradles the foot rather than cramping it. The upper has been constructed with molded PU that feels supportive while also providing drag-protection for those who slide on hard courts. The internal glove bootie system adds to the comfort and allows these shoes to breathe easily; not to mention the signature Head Cooling System that vents the feet with a mesh window under the arches. Dynafoam under your heels feels plush and alleviates shock, while EVA foam under the forefoot is more responsive for quick explosive movements. Head's signature Hybrasion+ rubber is formed into full herringbone tread pattern that is designed to give you maximum grip when playing on clay courts.
