Justin Bieber has hinted at a collaboration with Crocs, causing the foam shoe makers shares to rocket.

The Canadian pop-star posted a picture on his Instagram account showing a pair of orange Crocs floating in a swimming pool. Underneath, the one-word caption read "Soon".

The post has been liked more than a million times, including by the official Insta-account of Crocs.

Since the post by the Love Yourself singer, shares of Crocs Inc have also surged by 13 per cent, their highest intraday level since 2007, according to Bloomberg.

If the collaboration pans out, the footwear brand could be the latest addition to Bieber's Drew House collection. The unisex fashion brand features loungewear and accessories, including hotel slippers, hoodies and plush toys.

In partnering with Crocs, Bieber would join a growing list of celebrity names that have paired up with the once-uncool brand.

Musicians Post Malone and Bad Bunny have already been linked to Crocs and actors Zooey Deschanel, Natalie Dormer and model Suzu Hirose all previously collaborated with the clog.

It's not the first time Bieber has shown his fondness for the foam shoe. Last year, he was pictured in Los Angeles in a hot pink pair of Crocs, decorated with an array of charms.

Last year, Crocs were the 13th most popular footwear brand among average-income female teenagers, according to data from Piper Sandler. This was a move up from 30th place in 2017.
