The Meindl Borneo Pro would be my choice. I bought my first pair 22 years ago, and my second about 6 years ago. Both pairs are still going, the older pair has developed a leak where the leather has cracked. They are pretty rugged and not heavy, and they are so comfortable! I wear them most days from about September through to April, for dog walking and conservation work. I got a pair last year in return for some work, and I haven't worn them yet, I figure between the three pairs I have walking boots to outlast me.
