Real Crocs are recognisable thanks to a number of characteristics. For example, real Crocs are only produced in China, Italy, Mexico, Vietnam and Bosnia. Aside from this, genuine Crocs always feature buttons with the authentic Crocs logo printed on them. This logo consists of a crocodile with six humps and two hands, each with three fingers. Thanks to these traits (and a handful of others) you shouldn't have any trouble recognising a pair of real Crocs.
