Bulle blue

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.

Tropo sole - Your mini-trampoline

The Bulle blue has a Tropo sole and therefore a lower Rebound-Effect. This sole has an improved profile for squeaky floors and a «kybun light» feeling with less initial reactions. The Tropo sole is the successor of the popular Cirrus sole and has all the advantages of the previous models. It is designed to roll better in the backfoot area than the Cirrus sole. Furthermore, it has an ideal fit for almost every foot. This type of sole offers a slightly reduced intensity and effect. With its «kybun-light» feeling, it is ideal for people with weaknesses in the muscular system or balance disorders. Also for all exercise fanatics, who don't want to miss the kybun shoes during sports activities. Perfect for sports such as tennis, volleyball, jogging, etc., where it is less about the winning and more about pain-free movement. The sole has no air cylinder due to the lower height. The Tropo sole also has the optimal kybun grip on all floors.
