What are these crocs of which you all speak?! I have only started noticing them the last couple of days (I'm a bit slow, me) but what are they for? (I mean, they look like they have been developed for something specific like rockpooling or sommat). Do they do something special? Are the holes just decorative? Does everyone in the world like them but me? No offence meant to anyone who loves them, I just don't get it!
