Justin Bieber launched his right Yeezy into the crowd during the Wireless Festival in Germany, and the lucky fan who caught it already has it posted on eBay for a starting bid of 5,000 euros (about $5, 670 USD).

The seller posted many pictures to prove its authenticity, and claims that part of the proceedings would be donated. Bieber’s left shoe is also online, but not for sale. It has an Instagram page with 5,000 followers and a picture JB’s shoe size in case you were curious.
