The A730 focuses on absolute stability in motion. While the ENERGYMAX 3.0 cushioning reduces stress in the ankle, the significant strengthened heel and back area ensures a secure fit. The additional side TPU applications do not only reduce the risk of falling over after jumps and sidesteps, but also protect the material from abrasion on the hall floor. To prevent unwanted twist of the outer sole and overall fabric, the inserted carbon part provides an extremely resilient framework.
