The most unexpected collaborations of 2018 may as well go to the recent team up between multi-platinum-recording artist Post Malone and footwear manufacture Crocs. alone’s Crocs, which retail for $60, sold out in under 10 minutes. Apparently even Madonna was unable to purchase a pair and messaged Malone on Instagram asking where she could get some. Collaborations like this mark a strange new chapter for Crocs, arguably the most divisive shoe brand in recent history. After first hitting stores in 2004, they grew rapidly and left their foam footprint across the world. In 2007 they created $847m in revenue and CNN described them as “2007’s hottest shoe”. But soon after, Crocs became code for a style faux pas, the ultimate symbol that you’ve given up all hope on your personal appearance.
