P.W.
My kids always fell for the " I don't know where they went, I guess we will have to go get some more" trick. If you make them disappear in the night, the only thing he can do is pitch a fit for a while, look for them, and finally will have to resign to the fact that he indeed has to go with you to get some more shoes. I did it with their bottles too--we made a big deal about going to get some sippy cups...since the store was " all out of bottles" LOL.
