I realize that I am a bit late on this thread, but wanted to mention Korkers Outfitters. They have convertible soles so if the soles wear out all you have to do is buy a new set and change them out. They also are very comfortable and well made IMHO. I bought them for the ability to change from a wading type sole to a hiking type sole. I figured it would be great for being able to hike into some of those blue liners without wearing out or messing up the felt.
One last point about Korkers is that they tend to run a size smaller than most boots or shoes. In other words if you wear a size nine street shoe, you'd need a sixe ten in the Korkers. I suggest that you purchase them in a shop where you will be able to try them on. I am not sure of LRO sells them
