MBT inventor Karl Müller presents the kybun shoe

In 1996 the engineer Karl Müller invented the MBT shoe, revolutionising the shoe industry with its "rolling sole". After the sale of MBT in September 2006 Karl Müller developed the elastic-springy trampoline sole of his new brand kybun.

With kybun shoes you can experience the unique walk-on-air feeling immediately. "In kybun, you don't walk: you float. The walk-on-air feeling is unique", explains Karl Müller. Inside the kybun shoe, the foot rests directly on a springy, elastic sole, which provides the foot with maximum freedom of movement. This elasticity and flexibility in all directions is excellent training for the musculature and you feel how well it absorbs, shocks and adapts to your feet. Whether at work or at home, on a hike, walking around town, kybun shoes are so comfortable to wear that you’ll never want to take them off.

What makes Karl Müller's latest shoe invention so unique?


kybun shoes make exercising fun
Dr med. Christian Sommer, a consultant for orthopaedic surgery, believes that the kybun shoe is the ideal training device for everyday life. It soothes the entire musculoskeletal system and relaxes the spine. Eight years after her accident, Erika Wissmann can effortlessly walk again – thanks to the kybun shoe, which is very comfortable to wear. Dr med. Markus Müller can decrease the dose of pain medication he prescribes to his patients with osteoarthritis in their legs thanks to the extraordinary absorption properties of the kybun shoe. Reto Scherrer, who works as a radio and television moderator, is also grateful for the great level of comfort the shoes have brought him. He can now comfortably stay on his feet for as long as ten hours each day.

Everyone can improve their health with kybun shoes – without it even costing them any time.

Function/medical use

The kybun shoe is the perfect shoe for people who have foot problems such as bunions or heel spurs, since its soft, elastic material continuously and dynamically adapts to the shape of the sole of the foot.

I already knew about the predecessor MBT shoes and found out about the new style from my colleagues. I was impressed right from the start. I love the feeling of walking on sand or clay. You can experience this feeling in nature, but wearing shoes that give you the feeling all day long is simply amazing.
