Hip-hop star Kendrick Lamar has designed a pair of Reebok sneakers inspired by his upbringing in the gang-divided neighborhoods of Compton, California. Though the tongue of the each shoe says “neutral,” Lamar alludes to the West Coast Bloods and Crips gangs on the shoe heels, with a bold “BLUE” on the left and “RED” on the right sneaker. The design appears on the classic Ventilators, which turn 25 this year.
