Hi,
I just stick such things in the hot water cupboard (Great place for mittens in the winter if you live where winter requires mittens). If you have a long drive, then stuff your wading boots with a few pages from the mornings news paper. When you get home, the paper will be soaking wet, and toss it out. This will have at least drawn out quite a bit of moisture from the boots, reducing the water that has to be evaporated. Repeatedly stuffing boots with newspaper, and removing and replacing the newspaper every so often, was one way to speed up drying boots, but you do have to "tend to them" every so often. Also, the newsprint can stain your boots, so don't do it if you're worried about that.
