Our compensation insoles are made of agglomerated cork on a flexible resin base and recovered with a leather coating. Those insoles are designed to correct or compensate for a leg shorter than the other or used for increasing someone's height.

The compensation requires the use of incompressible materials for a rigorous and permanent correction.

It is important to use compensation insoles at all times while in standing upright position. Therefore you can either put the insole on all you shoes, boots or slippers, or you can move it from a shoe to any other one.

The insole must be placed on the shoe concerning the shortest leg.

What height to choose for the insole?

We recommend in the beginning to use our calculator (see above). Its intuitive and easy operation will ensure you to get an accurate and fast result.

Example 1:

A 57 years old woman has been informed following a recent hip surgery that she has a swing of her pelvis. This swing is 19 millimeters high and affects her left leg (this means her left leg is 19 millimeters shorter than her right one). In this case, the correct height of the compensation insole must be 12 millimeters, which represents 63% of the deficit.

Example 2:

A 46 years old man is diagnosed with a low back pain. An X-ray shows a Leg length Inequality (LLI) of 31 millimeters. The height of the compensation sole must be 18 millimeters, which represents 58% of the deficit. However, during the two first months, the compensation should be progressive in order to get an optimal result. For the first month we advise him to use a 9 millimeters compensation insole then a 13 millimeters one for the second month. Finally, starting from the third month, he can definitively use an 18 millimeters high compensation insole. This step by step process has a positive impact on patient’s quality of life. In addition to be better tolerated, it reduces potential biomechanical troubles linked to the rebalanced pelvis process.


If you cannot determine the right height for the insole, do not hesitate to contact us by using the form "contact us". We will work together to find the best solution.

Our insoles are available with the thickness of 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm and 35mm.

Concerned pathologies

  • The Leg Length Inequality

    The Leg Length Inequality (LLI) is validated by a radiography. It corresponds to the difference of height between the two legs, measured at the top of the femoral heads.

    Radiography of the pelvis

    Radiography of the pelvis front, patient standing

    The first consequence of the LLI is the inclination of the pelvis at the front.

    This swing of the pelvis forces the spine in a scoliosis position or a real lumbar scoliosis, creating an imbalance of the muscle, ligament and joint tensions. This is how musculoskeletal disorders can settle in, together with the pains that accompany them.

    It is important from this point on to wear the heel compensation in incompressible materials with a height adapted to correct the LLI and reestablish the functional harmony.

     Impact of a leg shorter than the other

    The studies published on the Leg Length Inequality (LLI) reveals that 8 persons out of 10 have one leg shorter than the other. (A panel of population free of fractures, surgery or diseases influencing the growth of the lower limbs)

    Percentage of population with unequal leg length

    Percentage of population with unequal leg length

    The synthesis of this work highlights several points :

    - First of all, there is a large disparity in the measured differences (from 3 mm to 22 mm of difference in length between the two legs)

    - 38% have a deficit equal or superior to 10 mm.

    - Only 14% correct their swing of the pelvis by wearing a heel compensation.

    - Last of all, despite the fact that the LLI is as present in women as it is in men, the women are 5 times fewer than men to correct their swing of the pelvis by wearing a heel compensation ( the main reason to this being the  aesthetic concern).

    Please note, in margin of these studies, after a hip surgery, after the placement of a prosthetic of femoral head, after sever fracture of the lower limbs or a sever osteoarthritis of the knee or of the hip, it is interesting to control the right balance of the pelvis by all ad hoc means recommended by your doctor. This will allow to check the relevance of a correction and therefore to prevent possible pain episodes.
