The first thing you'll need to know is where to start. The ankle is easy to sink into, since that's where the lake and river and pond are, but it's hard to get to unless you're coming from the knees. The heel's a bit calloused, but there's a little crack near the toes where you can probably slip in.
From there, I guess it depends on where you're going. If you're lucky, you can catch the flight from Albuquerque if you drive in from Corrales, and that'll leave you nicely above the arch. Then you can take The Badger if you're looking to go back a bit toward the path by the Christmas socks, so long as you watch our for wild creatures and rogue bits of science.
Once you're out of Michigan, if you're still looking to go up, you can probably use the wall; just make sure you don't accidentally end up in Narnia. It's not a bad place to go, but it probably isn't where you're looking for, since you'll already have bypassed Hyrule, much of history, and all the other between places lying beneath the blank space.
At that point, you're just about to the waters I mentioned earlier, the ones at the ankle. Beyond that is uncharted territory, as far as this particular map is concerned.
Oh, were you looking for what I've left behind?
If I've done that right, you won't need me to direct you there.
