The Trak Shak is available to attend any corporate, church or school health fair. We bring along the iStep machine from Aetrex, which is a pressure plate attached to a computer that produces a digital image of our clients foot. We use that image to recommend proper footwear and/ororthotics. All we need is an invitation and a power supply. Call 205-870-5644 or email [email protected] to get us out to your next health fair.
