According to a group of German scientists, the research which they conducted showed that plastic crocs, a popular type of sandals, are filled carcinogenic compounds. The researchers tested 10 pairs of the best brands of crocs made from plastic. The results showed that they contained around 60% aromatic polycyclic hydrocarbons.

This is a very harmful substance which causes cell mutation and cancer. It’s toxic and carcinogenic and penetrates the body through inhalation or through the skin. The research showed that the black crocs contained the highest amount of this cancerous substance. Therefore, the best way to stay safe is to avoid wearing these sandals altogether or to put on socks before you put the sandals on.

However, the original brand of crocs didn’t contain any carcinogenic substances, but they do contain solvents which may cause allergies.
