I like the uninsulated Xtra-Tuffs, with a pair of merino wool socks. I need to new ones this year, as well. I've had my older pair for 9 or 10 seasons now, and they are finally giving up on me. They are cracking at the ankles.
The newer pair of XT's are a huge disappointment, though. I bought them in 2008, and they gave up after only three seasons.
While I hope my next pair of XT's are more like my first pair, I doubt I'll ever own another pair of Muck boots, though. The toe cracked on one of the boots at about six months, and they have progressively fallen apart ever since. They have been water tight up to this season, even though they looked like crap, but I got wet feet at the boat ramp last weekend. They're toast.
