We can't really pinpoint when Crocs became super popular, but we can pinpoint when podiatrists told us to stop wearing them. That time is right now.
It's been reported by many podiatrists that Crocs can actually cause more harm to your feet than good. According to Dr Megan Lahey, with the Illinois Bone and Joint Institute, Crocs may offer nice arch support, but they are in no way suited for all day use.
"These shoes do not adequately secure the heel. When the heel is unstable, toes tend to grip which can lead to tendinitis, worsening of toe deformities, nail problems, corns and calluses. The same thing can happen with flip flops or any backless shoes as the heel is not secured," Lahey told Huffington post.
Not only that, but the flexible nature of Crocs are actually making us more susceptible to foot pain. Crocs have a flexible shank, which is the supportive arch between the heel and the toe.
The shank is what supports your foot as you walk, so having a flexible one is not good at all. According to Dr Alex Kor, the president of the American Academy of Podiatric Sports Medicine, he has patients coming into his office every day complaining of heel and arch pain, and the majority of them are wearing Crocs. Kor says the only types of people who should be wearing Crocs are those with high arches and those who suffer excessive swelling of their legs or ankles.
Long story short: Crocs are okay for a trip to the beach or a run to the store, but actual real-life doctors are telling us to stay away from them for long periods of time. Unless you want foot pain, that is.
