I saw an article resently written by Remi Warren. He shaved down some lightweight foam sandles and wore them in-between two pairs socks. Keeps feet quiet, it's pretty quick and easy to do and it also saves your feet from some of those pesky cactus, shale, and stickers.
That made me smile jenbickel about stalking and amost getting punched in the face. Surly some good advice to be wary on what you sneak up on.
