It's not as nice as the float tube system SHigSpeed is developing but I have a system that works pretty well for 2-4 mile hike-in lakes. My remote lakes float tube kit has consisted of an Outcast Trinity tube, homemade Bernouli bag pump, Outcast boot fins, lightweight Browning non-breathable waders (with nylon feet; I just picked up some UL NOS Red Balls for $10 at the FFF fair in E'burg), Korkers Guide boots, 2 pair of neoprene socks and of course an inflatable PFD collar. The Korkers with the Kling-On soles do double duty for hiking and to wear with the fins. The neoprene sox are used to fill out the Korkers; one pair is used for floating and some measure of protection for the waders, and another kept dry for the hiking. My younger brother and I are planning to do a 4-day 18-miler into some lakes this August that we did ~40 years ago. I want to use hiking boots that have better support than the Korkers can give. I think I should use the neoprene sox to help protect the waders, although I do have a great pair of Seasoft Ti Stealth neoprene dive booties. They are kind of heavy and bulky but would work instead of and possibly be lighter and pack smaller than the neoprene sox and some sort of water/wading shoe for the fins. I'm not asking for another debate about float tubes vs UL rafts but if you backpack a float tube any distance what do you use for boots and fins?
