Achilles Pain


How it feels

Achilles pain spans a range of symptoms from slight tenderness along the Achilles tendon to a sharp burning pain on the back of the heel right where the Achilles tendon attaches to the heel bone. It may or may not be accompanied by swelling.  

Common Causes   •   •   •   •   •   •   •   •   •   •   •   •   •

Achilles pain is usually caused by excessive or unbalanced tension in the Achilles tendon which causes micro tears at the attachment to the heel bone.  This can be due to a muscle imbalance (shortening of the calf muscle) or hyperpronation (fallen arches and ankles rolling in).  Hyperpronation causes the heel to lean in which typically causes increased tension on the inside attachment.  Achilles pain may also be caused by the heel counter of your shoes rubbing against the tendon or tendon attachment area.


Achilles pain is usually felt where the tendon attaches to the heel bone.

How to eliminate the pain

If the area is swollen and/or bruised, a trip to the doctor may be appropriate.  If it is not an acute situation, begin by checking if you have a problem with your shoes.  Make sure the heel counter on your shoes is not rubbing or squeezing the Achilles tendon.  If you determine your shoes are OK, hyperpronation is the most common cause.  Eliminating hyperpronation will most likely take care of the pain.  To check if shortening of the calf muscles are adding to the problem, elevate the heels in your shoes by placing a 1/4 inch lift underneath each heel to see if it lessens the pain.  For testing, trim from cardboard or similar material.  If heel lifts help reduce the discomfort, you can add heel lifts to your shoes.  You should also consider stretching exercises.
If the heel lifts do not help the pain, hyperpronation is most likely the issue.

An interesting note about custom orthotics:

Effectiveness of customised foot orthoses for Achilles tendinopathy: a randomised controlled trial Shannon E Munteanu, Lisa A Scott, Daniel R Bonanno, Karl B Landorf, Tania Pizzari, Jill L Cook, Hylton B Menz. Br J Sports Med doi:10.1136/bjsports-2014-093845

Methods This was a participant-blinded, parallel-group randomised controlled trial at a single centre (La Trobe University, Melbourne, Australia). One hundred and forty participants aged 18–55 years with mid-portion Achilles tendinopathy were randomised to receive eccentric calf muscle exercises with either customised foot orthoses (intervention group) or sham foot orthoses (control group). Allocation to intervention was concealed. The Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire was completed at baseline, then at 1, 3, 6 and 12 months, with 3 months being the primary end point. Differences between groups were analysed using intention to treat with analysis of covariance.

Results After randomisation into the customised foot orthoses group (n=67) or sham foot orthoses group (n=73), there was 70.7% follow-up of participants at 3 months. There were no significant differences between groups at any time point. At 3 months, the mean (SD) VISA-A score was 82.1 (16.3) and 79.2 (20.0) points for the customised and sham foot orthosis groups, respectively (adjusted mean difference (95% CI)=2.6 (−2.9 to 8.0), p=0.353). There were no clinically meaningful differences between groups in any of the secondary outcome measures.

Conclusions Customised foot orthoses, prescribed according to the protocol in this study, are no more effective than sham foot orthoses for reducing symptoms and improving function in people with mid-portion Achilles tendinopathy undergoing an eccentric calf muscle exercise programme.

If you hyperpronate, your arches drop from non-weight bearing (sitting with your feet on the ground) to weight bearing (standing).  When your arches drop, your ankles roll in and your heels lean in (evert) as illustrated in the picture.  Even a small amount of hyperpronation can cause Achilles pain.

The Solution - Posture Control Insoles®

Posture Control Insoles® do something no other orthotics can do:  Posture Control Insoles® are the only foot orthotics that naturally reduce hyperpronation by using your own muscles. Instead of weakening your feet with arch supports, you build strength through natural motion.

Even if you feel like your ankles are weak or lean out (supinate), chances are that your feet hyperpronate once your heels lift off the ground.  Posture Control Insoles® will naturally restore your foot function and posture by giving your feet - and your brain - a true read of the ground so your muscles can keep your feet and body balanced.  That's why Posture Control Insoles® work for so many different pain symptoms including Achilles pain.

The insoles are guaranteed to work for you.  Trim and wear them for 90 days.  If they do not relieve your symptoms to your satisfaction, you may return them for a full refund including shipping and handling charges.  You can also call us - We'll be glad to help you troubleshoot.
