The correct shoe care for your kybun shoe Returns / Size exchange
Springy like on a trampoline
The kybun shoe will impress you from the very first step. Just like on 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.
Elastic & springy
Perfect pressure distribution
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.
Strato sole - Your mini-trampoline
The Karl Grey-Blue has a Strato sole and therefore a higher Rebound-Effect. The Strato sole is designed to roll better in the backfoot area than previous kybun soles. This type of sole offers maximum effect as well as the ultimate in training performance and absorption. The foot pressure is evenly distributed and the full strength of the body is optimised. The elastic and springy material compensates poor postures and misalignments by stretching the posterior muscle chain with each step and the full-length sole profile with larger contact area to the ground ensures optimal grip on any surface.
Foot climate systemThe airy honeycomb structure of the kybun shoe creates an air-cushion between your foot and the ground. Every step pumps a fifth of the air volume into the foot space to create a comfortable shoe climate.
