Description

Safe3O is the name of the certified work and safety shoe. Hard work demands full concentration; safety and stability must not allow for any uncertainty. The Safe3O was developed precisely for these conditions: It combines the proven Künzli Ortho® stabilization system with the highest standards of modern occupational safety. S3-certified according to DIN EN ISO 20345, it offers comprehensive protection through a steel toe cap and puncture-resistant steel sole. The high shaft with thermoformable stabilizers reliably stabilizes the foot and ankle, even under heavy physical strain. Lateral reinforcements, a protective dust tongue, and the oil and petrol-resistant, antistatic tread sole provide safety in the most demanding environments. Thus, the Safe3O becomes a robust partner that guarantees stability, protection, and medically sound safety in every work situation.

Are Künzli Ortho® and Künzli Protect models recognized by health insurance and accident insurance companies?

Yes. The models are recognized as medical devices and can be reimbursed through health insurance or accident insurance, provided a corresponding prescription is available. The products are sold exclusively through our specialist retailers.
Can I order the Künzli Ortho® and Künzli Protect models from the online shop as a private individual?

Yes. The models can also be ordered as a self-payer, for example, if your insurance only covers two pairs per year and you need an additional pair, or if you want to wear Künzli Protect shoes prophylactically.

The five stripes

Künzli invents a lacing system with five stripes extending from the floor to the lacing. These provide support for the foot and make our sports shoes unmistakable. This detail becomes a symbol that accompanies us to this day.
