You can disagree all you like and I can't believe I am even bothering to explain to you as you cleary think you know all the answers.
This last pair, when I finished my day on the hill, I could poor the water out. And no, it did not come over the top of the boot, I was not in a river.
When I filled them with water it comes through the bottom in minutes.
They have now gone back as they are not waterproof. The other pairs have not bee so bad.
