How does this correlate with your moniker? You clearly aren't aiming to travel lean.

I used to pack them with their soles towards each other to keep the dirt together in plastic bags, but nowadays, I put the ankle part opposite each other like two L's with the soles on the outside, making it as rectangular as possible inside two plastic grocery bags to make sure the dirt doesn't escape (or at least has a hard time coming out). I pack them in one bag, then put another bag around the whole thing, with the opening of the first bag on the bottom of the second.
