Nike has always claimed its footwear features the best technology, the kind capable of making you faster or able to run farther distances. Its Air Soles and rubber outsoles have even helped people soar through the sky and tackle bad guys — or at least they did in the 1989 Batman starring Michael Keaton. The leading (Bat)man donned custom Nike Air Trainer Bat Boots, a pair of which is now up for auction with an expected selling price of $20,000 to $30,000.
Now 33 years old, the shoes feature a pair of black Air Trainer 3 sneakers customized with black leather collars that extend up towards the knee. Additional pieces of leather sit atop the leg to serve as armor plating. Due to the age of the costume prop, the Bat Boots show signs of aging including cracked leather and crumbling midsoles — meaning whoever buys them won’t be able to use them to recreate scenes from Batman. The boots are still collector’s items, however, and boast a price tag to match.
