Soft, elastic sole

Soft, elastic sole

The soft, elastic sole of the kyBoot/kyBounder gives your foot a pleasant feeling when walking and standing. Your foot can roll over naturally, much like it does when you walk barefoot on a natural surface. The three-dimensional freedom of movement on the soft, elastic material trains the foot musculature with every step.

This is healthy not only for your feet, but for your whole body. In the kyBoot/kyBounder, joints are loaded gently and are strengthened and mobilised at the same time.


The soft, elastic material of the kyBoot/kyBounder means that the sole/mat may feel unstable at first. That is the feeling experienced by people with weakened foot musculature or limited foot mobility.
When you walk in the kyBoot, your foot musculature is trained and you feel increasingly stable and safe.
The material adapts to the gait, dampens impacts and, depending on the weight of the wearer, is compressed to varying degrees.


The soft, elastic kyBoot sole can be very training-intensive in the beginning and can be too much for some. They feel unstable or unsafe on the sole.

The causes of the ‘wobbly’ feeling can include:

  • Unstable feet/ankles:
  • Excessive weight
  • Weakened foot musculature/untrained feet
  • Limited foot movement (stiff joints)
  • Balance disorders (such as those associated with neurological disorders)

Long-term consequences

People in developed nations walk on hard surfaces, either on cement or on hard, stiff shoe soles.

The feet adapt to these conditions. Because we scarcely roll our feet through the step or push off the toe, our foot musculature becomes increasingly weak and our feet generally immobile.

Foot pain and foot malpositions (hallux valgus, pes planus deformity, flatfoot, splayfoot etc.) are the results. These later lead to limping, pain, malpositions and damage to the higher joints (such as osteoarthritis of the knee or hip or back problems).

Conventional therapy

With foot pain or malpositions:

  • Physiotherapy: Active and passive movement therapy among other things
  • Avoiding footwear that harms your feet.
  • Walking barefoot a lot
  • Wearing orthopaedic insoles/supporting shoes

The kybun principle of operation – being proactive

The soft, elastic kyBoot sole may take some getting used to at first, but you will soon become comfortable with the new feeling of standing and walking.

The kyBoot sole trains your feet: It strengthens foot musculature, improves mobility and stimulates sensitivity. This provides active therapy for foot malpositions and trains foot coordination and balance.

Initial reactions

Specific initial reactions with instability in the kyBoot:

Lateral/medial rolling in the kyBoot over a long period of time can lead to pain and irritation in the foot or on the side of the knee. It is therefore important to prevent lateral/medial rolling and actively correct the foot position.

Application tips

If you feel too unstable in the kyBoot and there is not too much space in the shoe itself, we recommend a second-generation kyBoot model. This model has a slightly broader sole, making it somewhat more stable (seek further advice at a specialised kybun store).

If you still feel too unsafe walking in the kyBoot, we advise using the kyBounder. The kyBounder is available in three different thicknesses. This allows you to choose the thickness that is most comfortable for you (the thicker, the less stable, and the more intensive the training).
You can also hold on to a fixed object if you need additional support when using the kyBounder.
Please consult a kybun dealer.

If you initially experience uncertainty/instability in the kyBoot, taking slightly shorter steps may help.
