They hold us up all day long, they get us everywhere we need to go, and they connect our bodies to the earth. Some yoga teachers even call the feet the "roots" of the body. Yet for all that our feet do for us, we don't do much for them in return. We cram them into tight shoes, pound along on them all day, and generally ignore them unless they're giving us serious trouble. The result is that at some point in their lives, 7 of 10 people will suffer from foot problems, many of which are entirely preventable.
The first place to begin building awareness of your feet is in standing poses such as Tadasana (Mountain Pose). Before you start the pose, think about how you naturally stand. Notice how your weight falls, and then play with it by rocking forward and back, lifting first your toes, then your heels. If you tend to stand perched a little forward, try shifting your weight back a bit, and vice versa. Next, try lifting the arch of your foot while pushing down around the edges, creating both a sense of rooting into the earth and lifting energy up from the center. Once you start to do this, you'll find yourself more aware of your feet and distributing your weight better in your everyday life.
