With the Boston Marathon rapidly approaching, Dunkin’ Donuts unveiled this week a new product with which it had teamed with another Massachusetts-based company, Saucony footwear company. Together this week they launched the Saucony X Dunkin Kinvara 9 running sneaker. The limited-edition footwear is replete with Dunkin’s pink and orange colors as well as the company tag, “America Runs on Dunkin” up the heel of the shoe. She and her famous husband, New England Patriots quarterback Tom Brady, may both be adherents to rigid dietary regimes, but world famous model Giselle Bundchen gave an unqualified endorsement of Dunkin’ munchkins this week. In a profile piece in the Wall Street Journal, the supermodel exposed her dietary weak spot explaining about munchkins “I cannot have one. I have to have, like, 10. They’re so tiny. . . . It’s a guilty pleasure.” Now that’s an endorsement!
