In this film from Brazil, sneaker brand Mizuno presents us with an interesting fact -- Sao Paulo's garbage collectors can run up to 20 kilometers per day. The brand decided to celebrate these "unseen marathon runners" by giving them brand new sneakers for Christmas, as seen here. However, the film isn't just a (late) festive ad, it's one that celebrates a whole way of life as it follows the garbage trucks through the streets of Sao Paulo. F/Nazca Saatchi & Saatchi created the ad, which was directed by Fabricio Brambatti of Urso Morto and will run on social channels.
