Since you stated that it is a long hike in, I have to assume you will be pretty much alone in the small creeks, so, why not have a pair of hiking shoes of some sort plus something to wade the water in. Once you have hiked in, remove hiking shoes and hide them and put on whatever you want to wade in and when finished fishing, put hiking shoes back on and hike out. Just a thought....

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
