As for the Zamberlans that reduced your heel to hamburger, all I can say is, who knows what happened. Assuming these boots haven't caused you problems before, then the possible culprits run from sweaty feet stirring up some sock-to-skin friction to a trail that simply put unusual twists into your feet and boot.
It's possible, too, that after getting wet the boots shrank a little, which is something boots can doparticularly when soaked through repeatedly. Boots shrink mainly in the length, so that could account for a heel that's packed more tightly into the rear of the boot, causing a blister. If so, can the problem be fixed? Well, maybe. Wear the boots around the house some, using the warmth and moisture from your foot to soften the material and get it to relax. I'd also treat the uppers with something such as Nikwax FabricLeather Boot Treatment ($8; www.nikwax-usa.com). At the very least, you and the Zamberlans will have some time together to patch things up.
Otherwise, you might want to carry some shoes that are really meant to be soaked and use those for the portages. Salomon Pro Amphib Watershoes ($85; www.salomonoutdoor.com) are a good choice for that, offering traction, foot protection, and more than a worthy match for aqua dunkings.
