About kybun

Foot, knee, hip, or leg problems?

In modern times, a main cause of pain is our frequent sitting and standing on the hard, flat surfaces found in everyday life, damaging our joints and back.

The ‘walk-on-air’ kybun sole enables your foot to feel every detail of the floor. The soles of your feet will be gently stimulated with every step. The soft, springy air cushion provides optimum cushioning and your feet are strengthened. (Also see the kybun mat.)

Getting Started with kybun

Initial reactions can occasionally occur when changing from a supporting shoe to the kybun as the weakened foot now stands on an unstable air cushion. Pre-existing instability can stress the foot and leg musculature. When problems already exist, kybun shoes should not be worn too long to start. Use of kybun should be approached consciously as a therapy and training device; the footwear should be used as an everyday shoe only when the foot is sufficiently strengthened. Movement, coordination, and balancing ability will improve, but it is important to limit the time of use at the beginning because extended use may cause overexertion which can lead to pain. Temporarily suspend use if initial pains or irritations do occur while you begin to adapt the footwear. Training should be slowly increased over time.

Biomechanics of the Human Gait

The foot is the key to resolving many of the most common back, knee, and foot problems. This is due to the fact that most problems of the musculoskeletal system start at with the feet. Technical Information - read the latest knowledge on the biomechanics of the human gait.

kybun Soles & Sizing

See kybun Cirrus and Tropo Soles, recommended sizing for wide sole models, and the recommended sizing for "slim fit" soles.

Durability

Like any shoe, the uppers can remain in excellent to good condition for about two years, as long as you take proper care of them. They have a warranty against manufacturing defects for the first year. The air-cushion soles themselves are designed to last roughly four million steps for most people (equals 2,000 kilometres, or about two years of use for more active users) before losing so much of their elasticity that they feel a bit 'squishy,' for consumers up to 100 kg/220 lbs in weight. (The soles' optimal lifetime gets reduced by about 10% for every 10kg the user weighs over 100kg.)

Naming Note

kybun was initially known as kyBoot, prior to 2018.
