Sesamoiditis is a common ailment that affects the forefoot, typically in young people who engage in physical activity like running or dancing. Its most common symptom is pain in the ball-of-the-foot, especially on the medial or inner side. The term is a general description for any irritation of the sesamoid bones, which are tiny bones within the tendons that run to the big toe. Sesamoid bones acts a  pivot point allowing the big toe to bend downwards. There are normally 2 sesamoid bones in each foot however in some people this bone is split. The pain may start in the arch of the foot and slowly work its way down to the ball of the foot. Its this gradual onset that make sesamoid easy to diagnose.

Like the kneecap, the sesamoids function as a pulley, increasing the leverage of the tendons controlling the toe. Every time you push off against the toe the sesamoids are involved, and eventually they can become irritated, even fractured. Once the sesamoid bone is fractured it can be very difficult to cure because every time you walk you put additional pressure on the sesamoid bone. The primary cause of sesamoiditis is over pronation add this to increased activity and you will be feeling pain in the ball of your foot. However this can be controlled via insoles and rest. People suffering with sesamoiditis whom have been forced to live with the pain no longer have to put up with this condition while standing, walking or running. View the Dr Foot insoles range.

Orthotic Proof Sources and Safety Data.

The use of foot orthotics has been researched and tested by leading institutions around the world, and is widely accepted in the medical community. Foot orthotics/ foot insoles are used in both public and private hospitals and clinics.

Clinical studies and field research verify the value of orthotics in preventing and treating arch pain while improving the structural integrity of the ligaments and muscles around the ankle. Flexible orthotics control foot motion without restricting function and creating compensatory movement in other structures.
