Flexor tendonitis is an inflammation of the flexor tendons of the toes. The tendons that bend the toes originate from two muscles of the lower leg – the flexor digitorum longus and the flexor hallucis longus muscles. They run down the inside of the ankle and under the foot to the toes and are known as the flexor tendons.
Flexor tendonitis is less common than extensor tendonitis but can be more painful and disabling. It is more likely to occur in dancers.
Other names or similar foot conditions:
- Sesamoiditis
- Capsulitis
Symptoms:
- Tenderness along the course of the tendons
- Pain when the big toe is bent against resistance
- Pain on the inside back of the ankle

Signs to look for:
- Pain at toe off
- More pain after activity than before or during
Possible Causes:
- Overuse

Goals:
- Control motion in the foot and leg
- Align feet, ankles, knees and hips
- Move foot forward with as little lateral movement as possible
- Footwear that support legs and feet
How We Help:
Arch Supports:
- BioOrthotics exercising support with metatarsal lift
- Lower and thinner arch support with longitudinal and metatarsal support for use when shoes cannot accommodate the BioOrthotics exercising support
Shoes:
- Extra depth, double or triple depth shoe with high toe box, firm heel counter, rocker sole and connecting shank
- Smart footwear, such as heel to toe rockers, negative heel shoes or shoes with titanium springs
- Avoid flip-flops. Only wear sandals with a back and only the Orthaheel, Alegria or Aetrex brand
- Wear heels and pumps only as long as absolutely necessary
- Avoid going barefoot or do so on a minimal basis only
Activities:
- Regular stretching of gastrocnemius and soleus muscles, Achilles tendon and arch structure
- Rotation of weight bearing (dancing, walking) with non-weight bearing exercising, such as bicycling and swimming
