Thanks for all the responses. I spent most of Saturday, driving around to all the feed stores and tack shops around here, as well as TSC, trying on every type of rubber chore boot I could find. None of the styles of Muck boots were comfortable to me, and they were real hard to get on and off. I tried a bunch of other brands, but finally got a pair of Classic High style Bog boots at the local Agway. They suggested that I get one size bigger than I normally wear, because, like the Muck boots, they're hard to get on and off. But when I tried one size bigger on the Muck boots, they were really uncomfortable. I tried both my normal size 11 and a size 12, and the 12's were much easier to get on and off, and were still pretty comfortable. Plus the Bog boots were only $84.95, so they were much cheaper than any of the others, but at that point I no longer cared about the price. I've had the Bog boots for several days, and they're pretty comfortable, and get good traction on mud and ice, so I'm happy with them. Let's see how they hold up.
