There are several varieties of booties that go on over the shoe and extend up past the ankle. Then pull you rain pants down over the booties. I like the waterproof fabric ones with neoprene soles, cutout for the "cleat" on the sole, and a zipper on the back for easy entry. For platform pedals I just use a breadbag layered between two pairs of soxs. We are haveing the same rain trouble in Northern California. Set a new record for number of rainy days in March.
