Justin Bieber's new limited edition Crocs have proven so popular with footwear fans that they've already completely sold out after being released on Tuesday - in fact, according to Yahoo, the special sneaks were gone within just 90 minutes of going on sale.
An update on Instagram said: "This collaboration has sold out! Thank you!"
Many fans said they'd been struggling to get their hands on some, with one saying they'd been waiting 'in line since 9am', while another said: "I literally did not go to sleep just so I can have a better chance at getting these."
Crocs had teamed up with the singer to create a new design, which saw the famous clog style shoe given a youthful makeover with a bright yellow colour and custom Jibbitz charms.
"The Crocs X Justin Bieber with Drew Classic Clog pulls inspiration from the signature yellow of Bieber's personal clothing brand, Drew House, and includes eight custom Jibbitz™ charms designed to match his good vibes and laid-back style," a release said.
The Crocs x Justin Bieber with Drew (a nod to Bieber's middle name and his unisex clothing line, Drew House) shoes cost $59.99 (£46.41), although now that they've sold out via official outlets they're popping up on resale sites like StockX for more - including up to $150 (£116.05) on Grailed.
Announcing the collab, Bieber said in a statement: "As an artist, it's important that my creations stay true to myself and my style. I wear Crocs all the time, so designing my own pair came naturally.
"With these Crocs, I just focused on making something cool that I want to wear."
The Daily Mail reports that, when Bieber first teased the collaboration, Crocs stock shot up 13 per cent.
Heidi Cooley, Head of Global Marketing for Crocs, said: "Having a creative of Justin's caliber wearing Crocs shoes is of the highest compliments, and definitely hasn't gone unnoticed.
"But it's his belief in being true to yourself, a value we share, that makes this special partnership so authentic and exciting."
