Nevermind. I just removed the rubber soles that were peeling away and the rubber bed underneath is crumbling away. These cannot be repaired.
Sad. And I doubt I'll buy another pair of Meindls. $325 and only last 5 years of fairly infrequent use is unacceptable. My previous Brownings lasted nearly 10 years of harder use. I'm hunting in that pair now. They're not waterproof anymore and they are not as supportive but still warm and usable.
These were "Cabelas by Meindl" and some say the Cabelas ones were not made as well as "actual" Meindls but on the tag inside the tongue mine say "Meindl made in Germany". So if Meindl made a lesser product for the US market through Cabelas I see that as a prime way to ruin your reputation.
