The Swiss air-cushion shoe from kybun | walk-on-air
In kybun shoes (kyBoot) you walk on a soft, supple air cushion. You feel light as a feather and have a tremendous sense of pleasure. You will be a convert from the first step, and every further step you take will persuade you more.
Karl Müller invented the kybun shoe as the successor of the MBT trainers.
