Just wondering if the sizing of ankle openings in waterproof pants should allow for them to be put on over the boots while being worn. I have tried some on but with fully armoured boots they will not fit over. Is this normal or do you usually need to take off boots first, put waterproofs on, boots on, and then slip the pants over the tops. If I get caught out on the side of the road I don't really want to have to take boots off first. Al.
