A fresh new pair of canvas Vans low-tops will run you something like $50. But if you want to buy Mac DeMarco’s gnarled, mangled, vaguely sweat-stained old pair, you better be ready to put up five figures. DeMarco is selling an old pair of sneakers, one he’s worn onstage many times, on eBay. He’s signed one of them, and he’s donating the proceeds to the Willa Mae Rock Camp For Girls, a worthy cause. And people really like Mac DeMarco. Still, it’s pretty staggering that the bidding, as I’m writing this, has climbed to $10,000, with six days left in the auction. Here’s what DeMarco writes about the whole thing:

I’m selling an old pair of my shoes. I’ve John Hancocked the left shoe. Will anyone buy an old stinky pair of shoes? I don’t know. lets wait and see.

I’ll probably throw some other crap in the box before shipping it, I dunno what.

If you’re one of those kids who tried to take them off my feet while I was crowd surfing at some point this year, nice try jackass. But hey, here’s another opportunity for you to have them.

All of the profit will go to Willie Mae Rock Camp for Girls.

If you’re the one putting up this ridiculous dollar amount, you can rest easy. DeMarco has perfect eBay feedback.

DeMarco’s girlfriend Kira says they smell fine.
