There are many good wading boots out there, and everyone has their personal preference. I recommend trying on the boots you are interested in, and make sure they fit well.

Another thing to consider with studs, either in felt or rubber soles, is that if you step on the fly line with them, it does bad things.

I will keep using felts until they are banned everywhere I fish, if that ever happens. Just picked up a loaner pair today, a Cabelas closeout for $12.44!
