I think you could call any pair of shoes you wear in the kitchen, "kitchen shoes."
But I did end up getting a pair of Crocs. I really, really have a hatred for Crocs, but I bought a pair like this:http://www.amazon.com/gp/product/B0014JGDUC
They're actually made for use in a kitchen, so they don't have those stupid Croc holes, which wouldn't help you at all if you spilled boiling water or something. I've stood in them in the kitchen for a few hours at a time and they were pretty cushy.
The one thing I don't like is that my feet get kind of sweaty in them, which is gross.
