The science behind flecitec technology
the study
A study by the Institute for Applied Biomechanics in Tübingen revealed that ready-made shoes often cause unnecessary forefoot stress, contributing to orthopedic problems. The main causes are shoe shapes that are too narrow, insufficient anatomical toe room, and especially the so-called “balled toe” — a curved, uneven forefoot surface in the shoe that contradicts natural anatomy.
The study shows that a balled toe triggers numerous negative effects: undesirable deformation of the foot under load, increased energy expenditure while walking, longer ground reaction times, reduced stability, and a higher risk of stress reactions in the foot.
Simply slide the Flexitec spring-steel insole under the removable outsole of your shoes – your shoe tuning system for healthy movement and better performance is ready.
IT’S SO EASY
______________
„A flat forefoot support can significantly reduce these disadvantages and creates a stable, physiological contact surface.”
It enables better function in everyday life and sports, reduced fatigue, and increased resilience. A randomized pedobarography study with a subject group examined whether transversely stable and longitudinally flexible spring steel insoles compensate the deficiencies of conventional shoes.
The results show that such insoles improve foot stability.
adequate length and width, an anatomically shaped toe box, space for insoles, and a flat forefoot surface.

The solution
flexitec® & flexitec® powersole
With flexitec® insoles, there is an easy option to bring the foot back to its natural movement. In the shoe, no “groove” can form, and the foot can stand on a stable, level surface that protects and supports the foot while still offering full flexibility.
flexitec® insoles bring the healthy benefits of barefoot running into your favorite shoes. In shoes with flexitec®, you move more stable, more healthily, and you spare your back and joints.
Our unique insoles fit any shoe with a removable insole.

Dynamic
flexitec® Insoles relieve your muscles, joints, and spine. Noticeably more dynamism, stability, and comfort – in everyday life, during leisure, and in sports.
Efficiency
Through its combination of flexibility, torsion, and stability, the ultrathin steel spring core ensures, tefficient power transfer, secure support, and even pressure distribution in your shoe, forming the foundation for a natural-dynamic running experience.
Innovation
The patented wave structure with patented angle arrangements of 77° in the forefoot area and 103° at the heel is unique. It corresponds with the physiological rolling movement of the foot and supports the natural biomechanics of walking.
naturalness
When walking barefoot on a firm, level surface, the rolling motion is very natural:
First the heel comes into contact on the outside, then the body weight distributes forward along the outer edge of the foot, the longitudinal arch actively springs, and finally the push-off occurs via the forefoot. The foot continuously adapts through its own muscles and the sensory feedback from the ground, automatically finding a stable, neutral plane.
In modern shoes, this mechanism is limited. The typically soft, cushioned sole, an elevated heel (heel drop), and often insufficient support for the arches alter the natural position of the foot. As a result, the foot sinks into the shoe or tilts inward or outward.
Flexitec insoles compensate these differences, stabilize the longitudinal and transverse arches, and provide a consistent, even contact surface. In this way, the foot finds a plane surface within the shoe that closely resembles the natural situation when walking barefoot on a firm surface.
longevity
Flexitec inoles stabilize the foot in the shoe and promote more evenly rolling motion. As a result, forces are no longer concentrated on single areas of the insole, but spread more evenly. Typical wearout zones, such as one-sided heel wear, compressed inner edges, or unstable forefoot areas, are relieved. As a result, your shoe outwears more evenly and more slowly, which can noticeably extend its longevity.
