I don't think you can even use felt soled waders in AK anymore. Better check with ADF&G before shelling out any $$. Pretty sure you have to use rubber soles nowadays?

I'm assuming with the "felt nazi approved" comment he's got that figured out. None of the new treads are as good as felt on the snot slime, but with studs/cleats they work pretty well. OTOH vibram soles are much better for the hike in than the felts.
