The TPD insole is an orthotic device that brings the key features to control:

  • Excessive pronation or too much foot flattening in the foot (also known as hyper and over pronation)
  • This particularly helps a condition called Tibialis Posterior Dysfunction, a severe cause of arch height dropping
  • Tibialis Posterior Dysfuntion causes foot flattening on weight-bearing, accompanied by pain around the inside of the ankle, arch and inside of the shin. It is caused by failure of the tendon arising from the main arch supporting muscle of the foot. Treatment is urgent!
