Jordan Brand athlete and Chicago Bulls star Jimmy Butler can now add "substitute teacher" to his resume.

The shooting guard stopped by Chicago's Fenwick High School recently to surprise students there with a lesson about the Jordan Ultra.Fly, the latest performance Jordan shoe. Butler teamed up with Chicago native Easy Otabor to break down the silhouette with a lesson drawing on the law of action.

While the Jordan Ultra.Fly is a new design, it does have some heritage Jordan Brand references. The Kurim mesh used on the upper originated on 1989's Air Jordan 4 and the shoe is inspired in part by Michael Jordan's "Black Cat" nickname.
