Health and safety

The Centers for Medicare and Medicaid Services has approved a model of Crocs with molded insoles as diabetic footwear, which help wearers avoid foot injuries.[12]
Crocs are certified by the U.S. Ergonomics Council and the American Podiatric Medical Association.[13]
Footwear such as Crocs and flip-flops came under scrutiny in 2006 when children suffered injuries after the shoes became caught in escalator mechanisms.[14] This was due to the softness of the shoe's material combined with the relatively smaller size of children's feet.[15]
Rapid City Regional Hospital in Rapid City, South Dakota changed its dress code in 2007 to prohibit the sandal variants, along with those with Jibbitz holes, citing safety concerns, but still allowed closed-top "Professional" and the healthcare focused "Rx" Crocs to be worn.[16] Blekinge hospital in Sweden has banned the wearing of "Foppatoffels" (Swedish nickname derived from the owner of the company that imports the shoes, Peter "Foppa" Forsberg) by hospital staff, due to the concern that the shoes may build up static electricity and thus interfere with electronic equipment.[17][18] Vienna's city hospitals said they were banning popular Crocs plastic clogs, often worn by nursing staff, as they may pose safety risks for patients.[
