Girls Crocs

Crocs are shoes girls, or unisex?

My son wants toddler crocs (mainly because his sister has). My question (my wife agrees with me, but some friends disagree) is whether the Crocs shoes are girls or unisex? And it is a question of market acceptance. I do not what the manufacturer / retailer the bill as - of course, say they probably unisex, it would sell more shoes. Also, I am aware of the position of the parents that if she did not suffer, allow him to wear Crocs (since it is a simple trend anyway) - but is outside the scope of this issue, and is an entirely different problem.

Unisex, I saw an adult male is orange
