The best boot for the weight is the lightest boot that fits your foot the best, and provides all the stability, protection and features you need. No one boot is the best for everyone. Some brands are built on a narrow forefoot, wide heel, some are built narrow throughout or wide throughout, some accommodate a high arch, some accommodate neutral or flat feet. The best thing to do, if possible, is to go to a reputable shoe store or gear shop, describe your needs and wants and try on a bunch of shoes. Call the stores first and ask what their training program is like for fitting shoes & if any one person has the most training or experience. It makes a difference. For me, the Vasque Breeze GTX in a wide is my boot of choice for 80% of the year. At 2lb, 9oz, it is pretty light, while remaining very stable, comfortable and providing excellent traction. One of my brothers in sandals for 75% of the year, including hunting season. My other brother won't go off pavement with out his Asolo 520's. There's a myriad of great brands out there, since fit is so important, it's best to find the one that's best for you. Good luck!
