Socks? :D

Or most likely it's water damage or moisture trapped some place. You need to put your Sherlock Holmes hat on and investigate.

When I had this problem, the tub drain was leaking. I went in through the access panel in my back stair way and the wood was soaked. The walls and floors looked fine, but the wood was molding. I had to replace the plumbing parts and apply a 10-1 bleach solution to the wood several times before the smell went away. I hope this isn't what's going on with you, but a moldy smell usually means there's a leak somewhere.
