What is Achilles Tendonitis?
The Mechanics of Tendon Strain
Achilles Tendonitis is an overuse injury of the Achilles tendon, the band of tissue that connects calf muscles at the back of the lower leg to your heel bone.
It most commonly occurs in runners who have suddenly increased the intensity or duration of their runs. It's also common in middle-aged people who play sports, such as tennis or basketball, only on the weekends.
Common Symptoms:
- Mild ache in the back of the leg or above the heel after running or other sports activity.
- Episodes of more severe pain after prolonged running or stair climbing.
- Tenderness or stiffness, especially in the morning, which usually improves with mild activity.
Why Orthotics Are The Primary Treatment
The goal of treatment is to Reduce Tension.
Custom orthotics provide a heel lift to shorten the tendon-muscle unit, reducing strain. They also correct overpronation (inward rolling), which causes a twisting motion in the tendon that leads to micro-tears.
Fast Facts
- Prevalence: Common in runners and active adults.
- Cause: Overuse and biomechanical misalignment.
- Correction: 75% success rate with orthotic therapy.

Take Your QuizEffective Treatment Hierarchy
Medical consensus focuses on one goal for Achilles Tendonitis: Reduced Tension. You must shorten the muscle-tendon unit to allow healing.
1. R.I.C.E & Stretching
Rest, Ice, Compression
Rest and ice manage acute inflammation. Calf stretching is vital but must be done carefully to avoid over-straining the injured tendon further.
2. Shockwave & Surgery
Debridement / Repair
Shockwave therapy breaks up scar tissue. Surgery is used for ruptures or chronic tendinosis to remove damaged tissue, requiring months of immobilization.
3. Custom Orthotics
Heel Lift & Control
The medical standard. Custom orthotics feature a slight heel lift to shorten the tendon (reducing strain) and stabilize the heel to prevent the twisting motion that tears fibers.

Why Store-Bought Insoles Often Fail Achilles Tendonitis
Understanding the difference between simply cushioning the heel versus mechanically shortening the tendon is key to recovery.
Generic Insoles
mass produced
-
No Heel Lift
Most generic insoles are flat, failing to provide the slight lift needed to reduce tension on the Achilles tendon.
-
Lack of Stability
Generic heel cups allow the calcaneus to rock side-to-side, creating a "whipping" action that irritates the tendon.
-
Temporary Comfort Only
Soft foam compresses quickly, losing its ability to absorb shock or control motion.
