I have 2 pairs of regular shoes, mountain and road. I have 2 pairs of winter shoes, mountain and road, but the mountain ones do not work with my Frogs, and I no longer wear them. I am finding it hard to find a mountain version of my road winter shoes in my size (6). But, I don't mind the booties and an occasional chemical toe warmer. I also have a pair of Keen cycling sandals, but they also don't work with the Frogs. I used them when I had spds.
