If it's just rain and no snow you have more options. It is the salt that they use to melt snow that damages the leather. What type of style do you like? I would just get a pair of boots you like and put some protectant on it like Obenauf's LP. Then you can quickly wipe the water off the boots every time you get home.
Yes, it's just rain that's the issue. Just looking for some unorthodox options as everything I've seen so far seems a little too work-weary/americana-y.
