Muscle strengthening and stretching in the kybun shoe
The kybun shoe has a soft, elastic sole that does not limit foot mobility but provides full freedom for unrestricted movement in all directions. Standing on the soft, elastic surface with the associated instability in the kybun shoe trains the muscular system and straightens the body. A one-sided relieving posture is prevented. The load on both sides of the body is even, which counteracts tension. The foot can move freely while walking the way nature intended. By eliminating the heel, the foot sinks deep into the sole even on hard, flat surfaces. This stretches and relaxes the musculature and relieves back pain.
