With the possible cross contamination issues that can face us anglers nowadays, I've been thinking of trading in my felt soled boots and switching to the Aquastealth soles. I'm looking for some experienced opinions on the difference of these two soles. Are they pretty comparable when it comes to gripping the stream bottom? I fish a few streams that have many, many slick round rocks that are just begging to be slipped on. I occasionally slip when wearing felt soles, so I don't want to downgrade when it comes to grip. Does anybody have any opinions on this?
