Wearing sport shoes with air bags under the heels are one of the worst things you can do for your feet and function!  The more you put between your feet and ground—the more you decrease the quality of sensory information coming off the ground into your feet.  This lack of quality information creates a “clarity” issue for your brain and nervous system much like trying to navigate with a fuzzy map—it does not work well.  In addition to limiting sensory input off ground, tall air cushion heels alter the neutral foot/ankle position which challenges vertical column integrity.  Interestingly, studies show increased “heel cushion” increases the force the body puts into the ground in order to get ground feedback through the air sole—in reality even MORE force comes up through the body instead of less like the shoe companies want you to believe.  Please note–the optimal shock absorption is in your feet—NOT the shoes!  *For more information, see my Foot Products.
