Andre Reed Giving Bruce Smith Custom Shoes!

The Buffalo Bills are retiring Bruce Smith's jersey Thursday night -- but the most stylish tribute will come from his old teammate Andre Reed.

Reed -- who played with Smith on the '90s Super Bowl team -- hit up Billy Hobbs of True Blue Customs (the guy who made Avery Williamson's 9/11 cleats) and asked him to pimp out a pair of Nike Air Force 1s.

The result -- a nautical blue and red tribute ... complete with the Bills logo and an image of the legendary defensive end right on the shoes.

It gets better ... we're told Andre and Bruce will autograph the kicks and auction them off -- with proceeds benefiting the Boys & Girls Club of Buffalo.
