Because they are composed primarily of a cartiledge like material, which creates a barrier between the frozen environment beneath the penguins and their "feet". They also have very low blood flow. Thus, the cold cannot be transferred to the body.

Yikes... ok, ok, If the truth were to be known...

Penguins levitate :)

even if they levitated they'd freeze their snowballs off as it is so very unimagineably bitter cold!

Now see, I would've guessed exactly the opposite, that penguins have a highly developed vascular system through their feet that allows greater blood flow, keeping their feet warm.

What about polar bears and their fiber optic hairs and black skin! Now that's something.
