The Simms G3 wading boots are the best wading boots for aggressive hiking that I have ever used.
The Vibram rubber outer sole is decorated with a sparse collection of aluminum pucks.
I have two pairs. The earlier pair is on its 3rd resole. I use that one in the late fall and winter months as the uppers are a bit looser and roomier.
At this point, I am not sure that I will resole it for a 4th time. To be determined. If necessary I will gladly buy yet another pair of G3s until somebody comes along and says "Hey, I know what you are doing, these (some other) boots are better."
Science is not common sense. Much of it is devoted to a systematic documentation of what we do not know and understand.
