I have tried everything to waterproof my boots over the years on all types of leather, Gortex, and expensive boots to no avail and have never been able to keep my feet truly dry.
I finally gave up and have been wearing Felt Lined Rubber boots for years now and have never had wet or cold feet since.
Warm and Dry Feet is essential in all hunting conditions for an enjoyable hunting experience and you guys know what I mean!

A big part is stopping sweat. I regularly spray my feet with antiperspirant. It makes a huge difference.
