Felt soled wading boots or wading boots with fibrous sole are banned an all freshwaters of Alaska.  This is in an attempt to protect the State's ecosystems from  plant, animal and other invasive species.  We highly recommend that all fishing waders, boots and attire be washed with a 0.5 % water/chlorine solution before being used in Alaska and again when brought back to home waters.  It is us as anglers who can prevent the spread of invasives.
