Our self-sealing heels for sport shoes are specially designed to correct or compensate for a leg shorter than the other or used to increase someone’s height. They are made from one-piece of dense and light material which are comfortable.
Those heels are easy to clean and maintain by using a wet sponge or washing powder.
In order to ensure a permanent and rigorous compensation height, we use dimensionally stable materials to make our heels.
The heel is glued inside the shoe at the heel level, on the shortest leg side. (It has no designated side therefore it could be used on the right foot as well as on the left foot)
It is important to use compensation insoles at all times while in standing upright position. For that purpose, you should put those heels into all your sport shoes and sneakers.

Our heels compensation are available in the following height: 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.

What height to choose for the insole?
For the first time, we recommend you to use the above calculator, to determine the heels’ height you need. Its simple and straightforward use will able you to obtain an immediate and appropriate 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 do not succeed in finding the correct height for the insole, please, feel free to contact us by using the form "Contact us". We will work together to find the best solution.

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.
