The new PRO series uses calfskin on almost all uppers. This material is elastic and can adapt the boots to your feet and obtain a personalized fit. It uses Nike’s unique Lunarlon material, which effectively distributes the impact force of each step evenly on the entire steel plate. In addition, the foam core in the heel provides additional cushioning. It is made of rubber and follows an arc design to provide grip, traction, stability and a lot of contact with the ball. Players who are looking for mid-level boots appreciate the feel (adaptability and touch) of classic boots, but also value the modern look. Used in indoor courts or low-wear outdoor courts.
