Gentlemen, I'm just curious to your take on felt soled wading boots. I purchased some breatheable waders last year with the sock foot & had to buy boots to go with them. I had heard that if I was buying new boots to get the soles that help the grip on slick rocks. Now that I have a nice pair of boots with the felt soles I see reports that some places are trying to discontinue the use of them, because of the spread of some unwanted algae. Needless to say I'm not a wealthy man & don't have money to go buy new boots regularly, but on the other hand I love & cherish the sport of wade fly fishing & all the species of trout that I get to fish for & would never want to create a problem that would be detrimental to there survival. So I'm just curious to what some of you think. Thanks, Ben (bodyman50)
