My boots have become deadly

So I've had my boots for four years now. I've consistently been good about removing and drying the liners after I ski, particularily because my feet often get wet. I've never been able to locate the source of the leak or anything, so I always have assumed, disgusting as it is, that the water is foot-sweat.

They've always, to some extent, had a 'funny' odor. Definitely not a good one. My socks always reeked a little as well. If I could describe the smell, it would be a mix between 'wet dog' and 'rotting milk'.

So now to the reason why I think this has become a thread worthy experience. I was at Whistler skiing last week, and instead of drying my boots, I tossed them into the rocket box with my skis and went off clubbing. When I got back to the condo we rented, I took off my shoes and people dived for the balcony while I took off and double bagged my socks. We drove back the next day, and I (stupidly) put them down in the basement with my skis. A day later (yesterday), I went night skiing. Boots were a little cold and damp, but whatever, dry socks. When I got back last night, I removed the liners and put them on the radiator downstairs in our living room. I left my socks in my room, which reeked worse than ever before, and went off for 'nightly activities'.

Wake up this morning. My room smells like death. Culprit - two 'crusty' socks. My plant next to them has turned a bit of a funny light green. My liners are definitely dry, but the ENTIRE downstairs smells powerfully of wet, milky dog. 

So two things - for the short term, how the hell do I get this smell out before we have guests come over tonight, and 2) how can I get my boots to the level of odor that wont kill me when I drive up to the pass with them in my car?
