I have to praise the design and performance of the ZEN 7 "Silent Thunder"! The 270° wraparound TPU heel support provides excellent lockdown and improves torsional resistance by 50%, making every step steady and secure. The premium leather upper paired with the "air curtain" ventilation system ensures both lockdown and breathability. Each shoe in size US 9 weighs just 400g , lightweight and agile. Plus, with the bold AG branding and the custom tongue label with Aaron Gordon's signature, it combines great looks and outstanding performance.
