like NIB said i use the LLbean studded aquastealth soles. they have 3 or 4 different boot styles. I also have korkers i can wear if i am wading in bubbleweed..
i wore my neoprene bootfoots with no spikes the other day and almost fell in the drink 5 different times because i am so used to my studs
best thing is.. when the boots wear out, you can send them back- no questions asked.
