On Bill Russell, the original sneaker free agent

Decades ago, in the Louisiana native’s prime with Boston in the 1960s, Russell decided to endorse a shoe made right here in New England.

Star Boston Celtics forward Jaylen Brown is a sneaker free agent by design, his high standards for what he wants in footwear he would be endorsing with not only his name but also his values make the fit — both literal and metaphorical — critical.

But as is often the case with Brown and the Celtics, the forward-thinking star is following a path blazed long ago by a larger-than-life Boston icon, Hall of Fame Celtics big man Bill Russell. Decades ago, in the Louisiana native’s prime with Boston in the 1960s, Russell decided to endorse a shoe made right here in New England.

And he did it his way, creating a product that extended the life of that shoe company without simply being a transactional renting of Russell’s name and likeness.
