Not only are they unsightly, doctors are now saying there's no benefit to your feet in wearing them.
Crocs burst onto the scene a few years ago and divided opinion on whether they were the most ridiculous things around, or whether they were practical and comfortable footwear so why should it matter what they looked like?
Well it turns out that those who thought they were good for your feet were actually completely wrong.
According to The Huffington Post who consulted some podiatrists, the shoes which are made from a foam resin, are really, really bad for your feet.
The issue with them is that the open back leaves your heel unstable and does not support the foot properly.
"These shoes do not adequately secure the heel," Dr. Megan Leahy told the Huffington Post. "When the heel is unstable, toes tend to grip which can lead to tendinitis, worsening of toe deformities, nail problems, corns and calluses. "

Another problem with Crocs is that the shank (which is the supportive bit between the heel and the toe) is too flexible.
"Patients are more likely to have foot pain if their shoes bend in the shank," Dr. Alex Kor told The Huff Post.
"The only two types of patients that may benefit from wearing Crocs are patients that have a very high arch or those who suffer from excessive edema of their legs and ankle. But, under no circumstances can I suggest wearing Crocs 8 to 10 hours per day."
We hate to break it to you, but there is now no justifiable reason to wear those Crocs.
