One of my pair of Merrell boots is three years old, they stayed dry through a week of rainy days elk hunting the first year before succumbing . The other pair (same model) was wet the first day I hiked in wet grass this year. I also sprayed them liberally with silicone before departure.

Maybe they were just inferior products. I take precautions to not let water wick in from my sock tops, good gaiters.

So a boot like the Salomon Quest 4D should take care of it?
