NEW YORK “May the Fourth Be With You” is an unofficial holiday that celebrates Star Wars on May 4. This year, Crocs chose the day to celebrate the launch of its Star Wars-theme kids' collection. Working with marketing firm Domain, the brand staged a promotion that involved stormtroopers dancing outside of its New York flagship store. Created by the hip-pop duo Scott & Brendo, whose “Stormtropper Secrets” music video was a YouTube hit, the dance started on the street and led into the store. Inside, kids tried on shoes from the new collection.
