Brian, I guided in the Korkers guide boots last fall and never had one problem. There is a bit of wear by the BOA lace system, but not bad at all. I love the dial laces. I know it is a gimmick, but they work, and your boots don't get loose! I was wearing them with the rubber and studs bottom, and the insert never came out. A note on the studs: the package says to tighten them before use, and if you don't they will come loose!
Tight lines, Steve
