Man, so much good information in this thread.
So i have to put in my opinion also. This is one subject near and dear to my heart. Hang in there, I have a of advise.
Your feet are your number one concern. You already know that! Whatever boot you buy, needs to fit your feet well and to be "broken in" so that you can have healthy feet at the end of a long days hike/hunt, or for that matter multiple days hunting. Try on as many pairs as you can, put a boot on and walk around the store for as long as you can. The last boots I bought I wore, in the store, for over an hour before I made a decision.
The boots you mentioned, Meindel Alaskans, Danner Pronghorns and Schnees Pac boots are in different categories. Meindel boots are one of the better boots built. I have worn a couple of different pair for over 14 years. If those Alaskans are leaking, you have to look at a couple of things. If in fact they leaked and are defective, Cabela's has an excellent policy on their products. Call their customer service and ask to have them replaced. Thats if you haven't worn them in such a way as to damage the boot.
As stated by Daz, boot care is another important issue. Consider testing your boots when you have some spare time. Set them in the sink or the tub and see if water gets inside. Oh yeah, do the boot test in the sink when the wife is out of the house, this test doesn't sit well with most spouses. Trust me on this point !
If you are keeping the Alaskans and they leak, try and find the area that may be leaking, Is it damaged ? If not retreat them with something like "Sno Seal". This is one of the best "weather proofing" protectants i have every used. Its relatively inexpensive and lasts a season long. Wash the boots first and let them dry naturally. Hey, this reminds me, on your last trip, if you dried your boots over the fire and you got the boots to hot, you may have damaged them. Check the boots over really well.
There are many good boot companies out there,Kenetrek, Schnees, Meindel, Lowe, Vasque, Solomon, Zamberlan, Scarpa, Garmont, Merrel, Cabela's, Danner, just to name a few.
I would look at what you have first, get them replaced by Cabela's. Next, retreat what you have, and then as Randy said, combine a good pair of gators with your boots. The gators will help prevent moisture from getting in.
I spent 9 days in Manitoba last October guiding duck and goose hunters and most ever day i was in my Kenetrek's, rain pants and Kenetrek gators. I went in the marsh up to my knees on three occasions and never got my feet wet. My pants and legs were wet but not my feet.
Hey, just to give you an idea. I live and work in boots also. I have owned a pair from just about every manufacturer there is. Currently i have 9 working pairs of boots that i trade back and forts on.
My favorites are Kenetrek, Cabelas, Lowe and Schnees. These companies are not only well made but have excellent customer service.
Good luck and keep us posted.
