Springy like a trampoline
The kybun shoe will impress you from the very first step. Just like a trampoline, it provides you with a relaxing and training effect all in ONE! The elastic springy sole trains and relieves your body at the same time. Put on your kybun shoes and start walking, enjoy the unique feeling and benefit from an integrated training experience.
The elastic springy trampoline effect offers the best quality and healthiest exercise you can find! As with the vital elements in nutrition, the trampoline effect is the primary source of your exercise. Depending on the selected style, the sole has a more intense (higher rebound-effect) or lighter (lower rebound-effect) trampoline effect.
Foot sensor technology
The kybun shoe‘s flexible, cushioned trampoline sole allows your feet to feel every detail of the ground, which stimulates the health-promoting receptors in your feet.
The novel kybun sole consists of specially developed multi-component polyurethane (PU), into which many tiny air bubbles have been sealed. This elastic springy air pad enables optimal cushioning.

Made in Italy - Montebelluna
The Karl Grey-Blue is produced in our own production facility in Montebelluna near Venice, Italy. We manufacture the Swiss air-cushion shoe and its elastic springy sole largely by hand, using a process that includes up to 40 different steps by a dedicated workforce of skilled shoemakers and kybun's Swiss high-tech sole robot. Both production facilities (Switzerland an northern Italy) follow the exact same manufacturing processes.
