Post Malone and Crocs are partnering with Musicians on Call to donate 10,000 pairs of Posty’s sold-out Duet Max Clog II to frontline workers at 70 U.S. hospitals. Malone released the black-and-pink-themed Duet Max Clog II shoe last month, and, just like his four previous Crocs shoes, they were sold out in less than a day. Malone also donated a pair of the Duet Max Clog II shoes to every student in his former Texas high school in December.
