First, my comments shouldn't be interpreted as negative toward Schnee's. Good company with a good product line.
I used to do all my caribou and moose hunting in Schnee's Hunter II boots. Every year my boots eventually soaked up enough water to completely wet them inside and out....the main boot and not the liner. This was true with new boots....sealed seams....Schnee's Boot Dressing....everything I could do to prep them for wet environments. I changed liners every day. It's just a fact that leather which is constantly wet will eventually get saturated and then the moisture moves inside the boot. Once damp, it became very difficult to keep my feet warm and dry all day in 30-40 degree weather. Additionally....
On my boots, the Y-shaped leather strap over the Achilles area collapsed repeatedly. This only happened after my boot leather got wet and stayed wet. The area would wrinkle and rub my Achilles tendon to the point of pain on both sides. To their credit, Schnee's replaced my boots twice for this, but the condition reoccurred. On my last pair, the inner lining of the rubber bottom (a tough white fabric of some sort) came loose. I sent them to Schnee's and was advised it happened because I wore them when the interior of the boot was damp (which was constantly) and that I needed to dry them out between wearings. Again to their credit, Schnee's rebuilt these and sent them back. I sold them immediately.
I have several hunting friends who brought Schnee's Hunter II boots on extended moose hunts and basically had constantly damp boots and cold feet. They (and I) have changed to different boots which are 100% waterproof. My message isn't anti-Schnee's....it's more about how rubber bottom-leather top pac boots can be problematic in extended cold, wet conditions.
I miss them in a way, because they are so nice and comfy when warm and dry. If I was going to go with them again, I would definitely go with pant legs outside the boot, and use tall gaiters to help shed water off them.
