Every year, shoe manufacturers create special edition models for the Boston Marathon. Adidas, the official footwear and apparel sponsor of the race, has unveiled the 2016 Boston Marathon version of its low-profile adizero Adios Boost 3 racing flat. It features a Boston Athletic Association print on the open mesh upper, along with the official B.A.A. logo on the top of the tongue and “Boston 2016” printed on the footbed. The shoe will be available in two colors—the iconic B.A.A. blue and yellow and adidas Equipment Green to commemorate the 25th anniversary of the brand’s equipment line and the first adidas Boston Marathon Anthem Jacket. The shoes will be officially unveiled at a launch party on April 7 at the Boston Marathon adidas RunBase store at 855 Boylston Street in Boston and also be sold at the 2016 John Hancock Sports & Fitness Expo in the days prior to the April 18 Boston Marathon. The adizero Adios Boost 3 weighs 7.9 ounces for a men’s size 9.0 and has a 10mm (23mm/13mm) heel-toe offset.
