About Posture Dynamics

ProKinetics® Insoles are manufactured and distributed worldwide by Posture Dynamics, which was founded in 1998.

We want to help people everywhere live more active, healthier, happier, pain free lives.

Challenging Mission  •   •   •   •   •   •   •   •   •   •   •   •

We offer ProKinetics® Insoles - featuring a holistic technology that helps people to literally walk their way right back into better posture and out of pain.

The challenge, frankly, is to persuade people they do not need and in most cases should not wear arch supports. It is a challenge we treasure because most people are just tickled to learn that ProKinetics® Insoles improve their foot and body mechanics, and in most cases that is enough to completely or significantly relieve musculoskeletal pain.  We teach people not to tough it out. Aches and pains are your body telling you that something is fundamentally wrong.  Faulty foot mechanics literally causes people to walk and run their way into bad posture and pain from their feet to their jaw. Although most people don't get in pain until their 30'and 40's it is a problem that starts in childhood and that is often aggravated by sports.  More people, including young people, seek medical help for musculoskeletal dysfunction and chronic pain than any other preventable disease.

Frankly, the biggest challenge we have is that the custom orthotics industry generates huge windfall profits from selling $600 custom orthotics.   You guessed it, our customers are the only ones that like the affordability of our insoles.  They like our performance guarantee too!


Part of our mission is to create a greater awareness - to help you realize that correct posture is as important as good nutrition and proper hydration. Before prescription drugs and surgery became the focus of medicine, parents all over the world encouraged their children to “stand and sit up straight” because the physical and mental benefits of good posture were intuitive and supported by the medical professions.   Harvard Medical Scholars published papers and books on how postural deficiencies could impair the health of every organ in the body. Unfortunately, today most doctors believe posture is something we cannot control – so they just don’t bother with it.  Just as it was discovered that you could learn to breathe correctly through biofeedback, your posture can also be automatically corrected through providing proper feedback to your feet.  People have been carrying water bottles for years.  This is far simpler - just put a pair of ProKinetics® Insoles in your shoes and forget about them.  That's all you need to do to take care of a significant problem.

Revolutionary Design

ProKinetics® Insoles are revolutionary because they stimulate the body to correct gait and posture naturally without conscious effort.  Based on a patented concept licensed to Posture Dynamics by Dr. Brian A. Rothbart, Posture Dynamics designed the ProKinetics® Insoles for optimum effectiveness, ease of use and affordability.  Tens of thousands of people have been freed from musculoskeletal, posture and body mechanics related pain.
