I also replaced mine for the same reason. I have really high arches too but went with Mastercraft insoles because they fit my foot better than the superfeet I tried. I change the insoles in pretty much every hunting boot for that reason.
I assume you mean Masterfit? Or does the boat company make insoles too?
What insole do you use? The Superfeet's work for me but, I'm not convinced that there's not something better out there.
