Michael Jordan -- Infamous 'Flu Game' Shoes Sell for $104k

Michael Jordan's disgusting sweaty shoes from Game 5 of the 1997 NBA Finals just sold for $104,765 at auction ... TMZ Sports has learned.

The sneaks were worn by Jordan during his famous Flu Game -- when the Chicago Bulls came back to win Game 5 in the '97 finals against the Utah Jazz ... even though MJ was sick as a dog. MJ scored 38 points, with 7 rebounds and 5 assists. The Bulls went on to win the Championship in Game 6.

The Flu Game is one of the most famous games in NBA history.

MJ signed the shoes for a ball boy who worked the game ... and they eventually ended up for auction this month on Grey Flannel Auctions. The auction finally ended this morning.

So far, it's unclear who placed the winning bid.

Insane.
