Celebrating the Boston Marathon, this special-edition Saucony Kinvara 9 was designed in partnership with a veritable New England institution — Dunkin’ Donuts. The shoe dropped in March 2018, carrying a mostly white base with unique flourishes denoting Dunkin’ staples: cascading sprinkles and a frosted donut cover the heel, while the Saucony logo on the forefoot is modified with the addition of coffee beans. Additional Dunkin’ branding is found on the tongue and sockliner.
