One such study was conducted by ETH Zurich, for example, in which kybun technology was compared with other market-leading health shoes and barefoot shoes.

The results showed that kybun shoes trigger greater movements in the foot and that the movement curves are more harmonious when stepping. The sole of the shoes significantly dampens the force exerted on the body in the first phase of the stride. Further details on 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.
