One of my first backcountry forays was a fly-fishing trail camp deep in the Gros Ventre Wilderness of Wyoming outside of Jackson. Since shelter, sleep systems, and food were provided already, we could afford to pack along a few more toys for the 10 mile hike into the camp.
Since we were fly fishing, we brought nylon stocking waders and Teva sandles. I loved the feeling of walking through water, very fun. Of course, the sandles and waders must have weighted 3 pounds. Eventually, though, they did suffer punctures caused while hiking around the rivers.
A good pair of lightweight waders that could withstand a bit of bushwhacking would be terrific, but you still have to add a lightweight water shoe if you don't want to constantly have wet footwear. Or is there another way to resolve the issue of additional footwear?
