When I don't hunt barefoot, I wear Cherokee-styled puckertoe/centerseam moccasins made of braintanned deer. Good stuff, but they get wet easily, I usually hunt barefoot at least until the dew dries a little. If the soles get stiff, a little grease (bear when I have it, lard when I don't) softens them up fine. I don't grease anything but the stiff parts (usually the very soles), in spite of what you'd think the grease doesn't do much to waterproof.
There's a heck of a good pattern here:

Once you've made the first pair and gotten over being nervous about cutting that fine hide, all you need is the hide, a sharp knife, a piece of charcoal from the fire for marking, and an awl - and your own feet for the pattern.
