Building on the success of the first version, the Nike GP Challenge 1.5 delivers comfort, stability, and support. Nike makes subtle improvements to the first version, which makes this shoe even more fitting for some of the best players in the world, including Jannik Sinner. Key design features include forefoot and heel Zoom Air units, a mid-foot stability plate, and high abrasion rubber on the outsole that is denser in strategic locations. Adding to the overall comfort, the upper material is lightweight, and breathable; this version has a tighter mesh weave for increased foot support. The toe-skin on the forefoot and medial side of the toe-box for is more durable for those players who drag, while the integrated lacing system and support strap on the lateral side will keep your feet secure on those lateral cuts. The outsole is designed for the wear and tear of hard courts, but will perform well on a variety of surfaces.

• Upper: Synthetic and mesh material for lightweight support and easy ventilation. Version 1.5 features a tighter mesh weave for improved support, and a more secure tongue gusset so it won't move around inside the shoes. Rubber drag-guard on the medial side of the toe-box, and extra padding around the ankle collar for a plush feel.
• Midsole: Zoom Air units located under the forefoot and heel for easy energy return and a smooth ride. Stability plate helps to resist torsional twisting of the shoes.
• Outsole: High abrasion rubber outsole in a herringbone design; rubber is more dense on the medial forefoot high wear region, and finer tread on the lateral side for sliding enhancement.
• Color: Hydrogen Blue / Navy
