Merrell Mens Erie Mid Waterproof Hiking Boot

I was thrilled when I first put these on because they were so light and comfortable which obviously is great, but I soon discovered they were not waterproof as the name so prominently suggests. They are certainly water resistant but after a couple of hours over three days walking in damp grass and a bit of light rain the boots were thoroughly soaked, My socks were damp, and the boots took about two days to dry out. Am I missing something here? am I supposed to be the one that waterproofs them? With the seemingly good reputation of this company I can only assume that the basic waterproofing step was skipped at the factory?
