i bought a pair of mendels perfects, loved the boot very waterproof comforable however they sqeaked so loudly i 'am returning them to cabelas tomorrow, i hunted elk in them this past season and i sure i chased every elk away within 1/4 mile. if anything they are a great excuse for not getting my elk lol
The first season I wore my Meindl's they squeaked as well. Then I used some mink oil on them and haven't had a problem since. 
I did then same and also used some leather conditioner and have good ever since. I still do mink oil every month or so but meindle perfects are the only boot I will ever have...
