Ever since clogs were launched in the market, they have been adored by adults and children alike for their comfy fit and vibrant colors. But experts say that these crocs like shoes may lead to cancers because of the various chemicals leaching from them.
You may love them or you may hate them. But one thing that everyone agrees too is that you cannot remain indifferent to the crocs like sandals and shoes that have flooded the market ever since their launch in 2002.
But time and again, questions have been raised about its safety.
This time, a research carried out in Germany has found that plastic clogs contain an alarming number of carcinogens which may put the wearer at a high risk of developing cancers.
The report has again stoked a debate on whether one should continue to keep wearing the clogs for their comfort or should completely do away with them for our own good.
The research was carried out by WDR, Cologne-based German Broadcaster Company, for its consumers. The company sent 10 pairs of plastic clogs, from reputed companies to the laboratory for testing. The laboratory was asked to look for the presence of solvents, heavy metals and polycyclic aromatic hydrocarbons (PAHs) in the plastic material used for manufacturing the clogs.
PAHs are highly carcinogenic substances which if absorbed can cause mutations in the cells. They are often used as softeners during manufacturing of shoes in the footwear industry. PAHs are predominantly present in black colored plastics though they may be present in plastics of other colors too. They generally produce their ill-effects after inhalation but they are also prone to be absorbed through the skin. The researchers were surprised to note that PAHs were present in six of the 10 samples tested. Their content was especially high in clogs which were black in color. It was even present in black straps and black buttons.
The solvents present in the footwear are absorbed through the skin. According to German authorities, solvents are classified as allergens and skin irritants. Ideally, they should completely degrade during the production process. However, because there are no set standards for the production processes, these solvents do not degrade completely and end up in the footwear.
Of the 10 pair of clogs tested, seven contained both heavy metals and solvents.
