Aside from Swizz Beatz and a select few others with exclusive contracts, rappers can be seen sporting as many sneaker brands as guest MCs on their albums. Just because you’re collaborating with Jay-Z doesn’t mean you gotta give 50 Cent the silent treatment, and switching back and forth between footwear peu is even easier.

Lamar got his at least a week early as these images from last Friday’s soldout show at LA’s Music Box prove; will you make the necessary preparations to ensure you get a pair of Black Cements before they run out of stock?
