Plastic clog maker Crocs has been subjected to accusations that its shoes are getting caught in escalators.

Parents in the US and Japan have reported a series of incidents where children wearing the shoes on escalators have been injured, reported Bloomberg.

According to other reports, retailers in the US have posted warnings at malls for wearers of such footwear to take the stairs or elevator instead.

Crocs spokespeople in the US were not able to immediately comment when contacted by just-style this afternoon (19 September).

Crocs has said its shoes are completely safe and blamed badly-maintained escalators.

The company, which earlier this week launched a new shoe for hospital staff, has been quoted as saying that it takes escalator safety very seriously as an issue. 

It has also urged people to pay particular attention when stepping onto or off escalators and walkways when wearing its shoes.
