Sam,
How you liking those boots?
I have a pair of the regular height wetlands boots, and the neoprene is taking a beating. Of course that's a lot on me as I'm wearing them in brush when it's wet out. I figure the high cuts would hold up a bit better.
Scott, the Muckmasters are my favorite chore boot for temps from about 0-50F. I get about 6 months out of them with constant use before they start getting a little wore out and potentially leak. Then I save the wore out pair for when it's below freezing or not that sloppy. Going on my 4 or 5th pair and really like them.
