I bought lowa tibets and absolutely love them. Fit perfectly, super comfortable. About 8 months later was my first long hunt with them, they soaked through the first day in we grass (wearing gators). Feet stayed wet for the entire 10 day hunt. Came home, sent them to lowa, they leak tested and confirmed they leaked so sent me a new pair. No way the new pair would leak right? So 5-6 months later I head back out west for another 10 day hunt...same thing, soaked through from wet grass. Wet feet for 10 days. Came home, called lowa, sent them back to them. They leaked tested and again confirmed they leaked so sent me another new pair. I still have this pair but only wear them when i know i won't be in constant wet. Since then i've been on a quest to find a pair of boots that fit me as well as the Lowas and I still cannot find anything as comfortable with the same support. I hope it is a lowa problem and not a problem with all GTX boots. I've done a few hunts in my Zamberlan 2092's so far no leaks. (they just aren't as comfortable....but manageable)
