How do you get foot odor out of a couch?

I spilled coffee with milk in my car and it was RANK. I used the product in the pet store to remove pet urine called Nature's Miracle and it worked great. You pour it on, let it soak in until it evaporates and the smell goes away. While not suggested, I sponge up the residue with a clean cloth as it seems gross to let it sit and marinate. Nature's Miracle is basically alcohol, so perhaps you would do as well to try this. But make sure to test a section before you pour all over your couch. May lift the color.
