Scientific studies and expert opinions

At kybun, the health and well-being of our customers comes first. You can find numerous testimonials from experts and customers that testify to the effectiveness and recommendations of our products.

One such study, for example, was conducted by the ETH Zurich, in which kybun technology was compared with other market-leading health shoes and barefoot walking. The results showed that kybun shoes trigger greater movements in the foot and that the movement curves are more harmonious when you walk in them. The sole of the shoes significantly dampens the force applied to the body during the primary stepping phase. More details about this study and its results can be found here.

kybun ETH study

Walking is the most important form of transportation and consequently people spend a lot of time on their feet.

To understand the influence of Karl sen. & jr. Müller's «kybun» and «Joya» to examine the gait pattern when walking and running as well as the forces on the feet, the Biomechanical Institute of the ETH Zurich carried out a study with gait analysis. The study included 12 test persons (barefoot, kybun, Joya, MBT and 3 test persons Joyssy), high-speed video recordings of the ground step, kinetic measurements of the ground reaction forces and kinematic measurements of the position and movement of the body.
