I look for fit and feel for sure. No doubt an inexpensive boot is inexpensive for reasons. Asking one boot to be comfortable and durable enough for miles and miles of hiking and yet OK for sitting in a blind is cold weather and remain truly water proof for eyars is a tall order.

As for "rubber" .... i do use a rubber boot during extremely wet conditions because
where I hunt, wet = sticky red clay mud by the bucket ! But i have found no rubber or rubber/neoprene boot that can survive years of walking and none that are not a "sweat box".

A good buy might be an Irish Setter brand, usually found at any Red Wing store. I
have a set that are about what you are describing. Do OK in subfreezing temps with proper socks, water proof so far and a good "hiker". Breaking the bank (??) .... I'd say expect to fork over about $150-$350 for a good quality boot such as you are describing.
