Again, I agree with AlmostThere. Only GoreTex (or other waterproof breathable) shoes I use are mids for snowshoes. In warmer months (like our balmy high of 48 in TM last weekend), I walk through the water and keep walking, feet dry as I walk. If it's constant in and out of water, I make sure to dry them out fully before bed and use dry socks ("sacred" socks) for sleeping. I use BodyGlide on feet and have not had any maceration issues even when continually crossing creeks on 18-30 mile days. And I'm generally blister-prone with ill fitting shoes/boots. Good shoes + good socks + BodyGlide + short gaiters = very happy feet for me. And my current favorite trail runner for backpacking: La Sportiva Ultra Raptor. Great stick, stiff sole, great underfoot protection. Good upper. The Wildcats drain better, but are a little less sticky, and are now my "know for sure I'm dousing my feet" shoes.
