I don't think I have cheesy toenails.
But, if you have thickening and yellowing of the toenails, you may have a fungal or yeast infection.

Like Guthers said, it's likely due to the bacteria.  The Brevibacteria that is used to ferment some cheeses is also present on our skin and concentrated around the feet causing odor.

Because milk and sweat are more similar than most people are happy thinking about.

I think it's because of Propionibacterium but probably also cornebacteria and many others.

Basically, bacteria in cheese and those that live on feet will share some genetics, and thus will often produce similar smells.

Did any of you even read the article above?  Why are you all trying to answer the question (wrongly) that was answered already?

This is great, I clipped my toenails and sniffed them, smelled like Parmesan, and I started thinking up this imaginary world where Parmesan is a product scraped from beneath the toenails of giant trolls. Then I read this and was happy.

Ah this realization that cheese and keratin sceretions, when eaten by bacteria produce the same consistence and flavor/odor.... Did humans develop a like for cheese because it smelt like really masculine men(excess testosterone causes the secretions nessicary to feed the bacteria that create the smell). It certainly wouldn't even be close to the first time humans like something because it smells like a particularly virile/fertile man or woman
