The pair of custom Nike Air Trainer Bat Boots worn by Michael Keaton in Tim Burton's Batman are now up for auction. Now 33 years old, these boots utilized a pair of black Air Trainers as the base where black leather was added to the collar and extended to the knee with additional thick pieces of leather added as "armor plating."
Due to the age of these costume props, they are showing the customary signs of aging in Nike shoes with cracked leather and crumbling midsole. These are expected to sell somewhere between $20,000 to $30,000 USD.
In other collectible news, a "Secret" notebook from the Johnny Depp Vs. Amber Heard trial has just sold for $15,000 USD.
