The Magic of Feet
Something definitely changes with the feet in different periods of your life. I think rather than calling it age, it's that awareness and sensitivity to them increase so that you notice more how things effect them. One year, I simply had to start over with each pair of shoes and see if my feet were okay with them. The instep area didn't want the tongue of a sneaker pressing in on it and compressing the bones, or restricting the mobility of my ankle. The other very cool thing I noticed on my own body as well as with clients, is that the heel bucks itself up to take the extra pressure it takes on, but it borrows that extra padding from the tissue either in the achilles that attaches there, and/or from the arch. If you want to relieve plantar fascitis, or tight calves/achilles, rub your heels!
