There is no uniform definition for the term cardiovascular disease. In the broadest sense, it encompasses all diseases of the heart and circulatory system. However, it is usually used for subsets of these. Here are some of the illnesses listed by the WHO:

  • High blood pressure
  • Diseases of the veins, lymphatic vessels and lymphatic nodes that are not classified elsewhere (e.g. thrombosis, varicose veins)
  • Ischaemic diseases (coronary heart disease and heart attack)
  • Pulmonary heart disease and pulmonary circulation diseases (pulmonary hypertension)
  • Cerebrovascular diseases (cerebral haemorrhage, stroke)
  • Arterial diseases (arterial occlusive disease)

In human medicine, all diseases of the heart, vessels and circulatory system that are congenital and not acquired due to injury are usually considered cardiovascular diseases, e.g.:

  • Heart disease
  • Congenital arteriovenous malformations
  • Tumours of the heart or vessels
  • Heart and vessel injuries

On occasion, the term cardiovascular disease is also used just for the heart and vascular diseases associated with arteriosclerosis and the risk factors of diabetes mellitus, smoking, lack of exercise, genetic predisposition etc.


  • Lack of exercise
  • Elevated cholesterol values
  • Excessive alcohol consumption
  • Smoking
  • Unhealthy diet
  • Stress

Long-term consequences

The above risk factors/causes lead to blood vessel damage and can result in a heart attack or stroke.

Conventional therapy

Exercise and a healthy diet can prevent heart disease. If a disease develops anyway, surgery is usually the only solution.

The kybun principle of operation – being proactive

Micro-interval training

We recommend ‘micro-interval walking’ as a highly efficient training method. Here the intervals between walking slowly and ‘lightly floating’ are between 15 and 30 seconds.

This change in speed is not just fun but also highly efficient:

- In the ‘lightly floating’ phase, the cardiovascular system is activated and the musculature is loosened.
- In the ‘walking slowly’ phase, the cardiovascular system is regenerated and coordination (fine musculature) is trained. This works better the slower you walk, because you then stand on one foot (unstable, soft, elastic kybun shoe) for longer.

We are convinced that there is no better form of exercise for the health of the entire body than this ‘micro-interval walking’. It is important to only float lightly for about 15 seconds and to walk slowly until the pulse has recovered sufficiently again. This also results in optimum fat burning.

Initial reactions

Specific initial reactions with existing cardiovascular problems:

In the beginning, great physical demand is placed on your body in the kybun shoe/on the kybun mat. Since your cardiovascular system works harder, you have to breathe harder and will get out of breath more quickly. Therefore it is important to heed the advice under ‘Application tips’!

Application tips

Reduce your walking speed a little in the beginning and only walk at a pace that allows you to talk to your partner.
If you are under the care of a doctor, we advise you to wear a pulse meter so you can keep to a pulse set for you personally by your doctor.

You should feel well at all times during kybun training! Feeling unwell is a sign that you are overtaxing your body and/or heart. Once again, adjust the speed of both intervals so that you feel good during training and avoid overstraining your body.

Check your body posture regularly: You should walk upright and keep the arms, shoulders and feet loose.
When you push the limits of your fitness, you tend to cramp up. This restricts blood circulation and the organs no longer receive an adequate supply of oxygen, which would force you to stop training after a short time.

Opinions/customer testimonials

I’m almost completely pain-free now. I have better circulation, particularly in my legs. I no longer get cramps in my calves and leg muscles. Like I said earlier, I can walk without any problems.

kybun shoes facilitate active, healthy movement in everyday life. Whether you are walking or standing, it trains your deep inner muscles, protects your joints and strengthens your muscles. It also relaxes the spine, activates the blood circulation and reduces fatigue.

I would highly recommend wearing kybun shoes during pregnancy. For me, it was the perfect shoe to wear during the day to relieve the increased pressure on my feet and other joints and gently strengthen my body at the same time. I often felt physically tired, but my kybun shoes motivated me to keep moving and remain active during my entire pregnancy. Walking is so comfortable that even on days when you’re tired, you still feel like walking for a few kilometres. And you feel very fit afterwards. Another thing I love about kybun shoes is how they activated circulation in my legs. I suffered from circulatory problems and would often suddenly feel a strong, shooting dizziness sensation, particularly in the mornings. That’s why I was so happy to find a shoe that activated my circulation! Wearing the shows, together with surgical stockings, really made me feel a lot better. I never had the back pain that many pregnant women suffer from. I don’t know if I was just lucky or if it was thanks to my daily exercise in my kybun shoes. I’m pregnant now for the second time and enjoying walking in my kybun shoe to relieve the strain on my body and exercise at the same time.
