I ordered a pair of Gasolina boots early last summer for use on the F6B and some of my other bikes where the thicker stiffer boots don't work. The style I ordered has an open sleeve type upper that wraps around and is secured with straps. The advantage is that your pants/leathers can go inside or outside the boot uppers as there is enough adjustment to allow different configurations. I haven't been rained on in these boots but just looking at them they look like your feet will get wet. They are comfortable. The second time I wore them we went to an aircraft meet and I tramped around in them all day with no ill effects.
