To those of you who bring along footwear to use around camp, what is your choice? I tried Crocs once, which are effective for water crossings and pretty comfortable, but i have found them way too bulky. I now typically bring flip-flops. They are lightweight and slim for packing. My conflict comes from middle of the night bathroom breaks during cold temps. I am usually wearing socks and those don't work with flip-flops. Suggestions please. (use as a secondary shoe for water crossing is not a consideration anymore. I prefer going barefoot, no matter the temps, because I find I'm more surefooted).
