I like the boot covers.
I rode across the Korean peninsula recently during a typhoon. It was early morning, I was hung over, and it was a horrible ride: rain, fog, mountain passes, nasty curves with gravel and mud wash, a rising sun in my eyes, very cold, etc.
To keep my boots and pant cuffs dry, I ended up using plastic grocery bags with rubber straps and duct tape around my calves. It worked wonders.
So though the ride was horrible, wet feet would have made it impossible.
These boot covers are the first, and so far only, Harley-Davidson product I've seen that are of any use. I will order myself a pair.
