The first step to total foot comfort is understanding a little bit more about your feet. Our feet are all unique to us, and come in many different shapes and sizes with particular characteristics and needs.
Aetrex’s patented iStep® Foot Scanning Technology quickly identifies your arch type, foot size and pressure points. This revolutionary technology then custom selects the ideal orthotic styles for your particular needs. With the right orthotic style and in combination with the proper footwear, you can prevent unnecessary foot pain and achieve maximum foot comfort to help you maintain a healthy lifestyle. In a matter of seconds you’ll be on your way to a better life.
