Uncoordinated is too general. I am uncoordinated. That prevents me from ever being a competent musician. But I wanted a word for the feet. Scree slopes used to terrify me, until I discovered that they act like a down escalator: You sink into them a foot or so, but then you stop sliding. Now I think they're fun. Rope bridges are fine: any time I can hold on I'm okay. Slippery logs are bad. Really, really bad. Too slippery and I won't attempt them. Find another way across or turn around. Logs that are not slippery are really hard, but I'll usually ask the guide to carry my pack, and then I generally make it. (I always hike with a guide.) I never try to cross really raging creeks on anything but a proper bridge. Again, suspension bridges are fine as long as there's something to hold on to. Too general. Only if I'm lucky. More often I land flat on my face. Anyway, tangle-toed is the word.
