TREDS Motorcycle Rain Overboot by Advantage Products Corp.: Finally a rain boot cover that really is simple to put on and off. These boot covers are molded of latex natural rubber. I used to use the "Totes" brand but even with the zipper, you had to first figure out which one was the right or left and then pull until it was over your boots. With these, there is no right or left and I had no trouble getting them on since they stretch so easily. The manufacturer claims that it actually can stretch 800% but I have no way of proving it other than just doing it. Since it is a single piece of molded rubber, it is 100% waterproof unless you cut it or stick a nail in it. I found walking in them almost like not having them on. The traction is excellent for when you have to put your foot down on wet pavement. They are available in a variety of sizes and if you check their website at http://www.treds.com you will find a chart telling you what size overboot you need for the size of your boot. I wear a size 9-1/2 boot and needed their medium. As you can see in the photo, there are snaps at the top so that you can close them tight around you boots even if you have large calf's.  You can order them from their website.
