well I had to replace my boots last yr, they were close to 10yrs old. I bought them from orvis when I started fly fishing, they were the felt soles and the cheapest that orvis had at the time, I think they were 79.00. well when i started looking to replace them, things had changed, i still went with the orvis, but i went with the studded soles. everyone was telling me that was the way to go that there soon wouldnt be any felt ones on the market. the studded soles in my opinion r the best thing that has happened to wading boots, i feel a whole lot safer in those than my old felt ones.
