Before Prince George wore them, Crocs were the sort of shoes everybody loved to hate.
But since the one-year-old was pictured wearing navy blue Crocs while watching his dad, the Duke of Cambridge, play in a charity polo match, sales have skyrocketed, reports the Huffington Post.
And this isn't the first time people have taken style tips from the Prince - in August 2014 George was pictured wearing a pair of dungarees from Neck & Neck, which sold out only the day after he wore it.
The style of Croc in question is in the "Crocband" collection, where the shoes have two colours and a band along the rim of the shoe.
Now that is a lot of Crocs...
Daniel Silverfield, head of vendor management, footwear and accessories at Amazon.co.uk, said: "We've seen a massive increase in sales of kids' Crocband Crocs since the photo of him wearing a pair was released."
The shoes are enjoying a "sixteenfold sales increase" on Amazon, as well as a 1,500% increase in worldwide sales.
George was also responsible for personalised baby clothes retailer My1stYears selling over 1,200 jumpers in just four hours after a family portait showed the Prince wearing a baby blue jumper with his name embedded on the chest for Mother's Day 2013.
Fashion brand Cath Kidston also had to rush to restock their knitted children's guard tank top after official Christmas photographs of Prince George wearing the designers product were released last year.
