2013 | Nike Air Tech Challenge ? | US11 | Andrea Agassi

Nike Air Tech Challenge II (2013) – Size US 11 / EU 45 – Approx. 30.5 cm Outsole Length

Originally designed for tennis legend Andre Agassi, the Nike Air Tech Challenge II debuted in 1989 as a bold statement in both performance and aesthetics. This 2013 reissue faithfully revives one of the most influential silhouettes of Nike’s late-80s tennis line — famous for its vibrant color blocking, visible Air cushioning, and aggressive midsole design that later inspired models like the Air Yeezy 2.

This particular pair features a clean white leather base accented by bright orange and soft blue detailing, echoing the energy of Agassi’s rebellious on-court style. With its mix of retro sport design and streetwear relevance, the Air Tech Challenge II remains a cult classic sought after by collectors, athletes, and vintage Nike fans alike.

Details:
• Model: Nike Air Tech Challenge II
• Year: 2013
• Made in China
• Outsole length approx. 30.5 cm
• Size US 11 / EU 45 / 29 cm (I feel Nike runs small in general)

Condition:
Sings of wear, minor damages and marks present. Lining and insole show minor use. Please refer to all photos for accurate representation.

Historical Significance:
The Air Tech Challenge line defined the late-80s and early-90s tennis aesthetic — flashy, unconventional, and performance-driven. Agassi’s partnership with Nike helped introduce color and personality to tennis gear, breaking from the all-white tradition. The silhouette’s design DNA later influenced Nike’s cross-training and lifestyle lines, giving it enduring legacy value among collectors.

Although tagged as EU 45, the fit feels smaller, so I am listing it as EU 44 for accuracy.
