This is a Photoshop job of Croc Martens, the make-believe unholy lovechild of a Doc Marten boot and Croc sandal. They're not real, but don't let that stop you from posting them on Facebook with a 'SHUT UP AND TAKE MY MONEY LOL'. Seriously though, there's no way a Doc Marten would ever bang a Croc. I don't even think those cheap $6 shoes my mom always bought me when I was a kid would bang a Croc. They would mark up the gymnasium floor and get me kicked out of PE though, so there's that.
Thanks to Blue16, who's convinced aquashoes are this summer's real fashion footwear.
