What are biothermal insoles?

Biothermal insoles are a medical device.

On 6 June 2008, by decision of the Office for Registration of Medicinal Products, Medical Devices and Biocidal Products, ul. Ząbkowska 41, Warsaw, they were entered in the Register of Medical Devices under no. PL/DR 016012.

What are they for?

Biothermal insoles are a supportive and preventive therapeutic aid for people with thermoregulation disorders.

What do they do in the body?

Biothermal insoles are designed to raise body temperature and improve blood circulation. With a daily thermal correction that works by shielding your own energy, hands and feet become warm. The insoles give warm feet to people with microcirculation disorders caused by diabetes and peripheral atherosclerosis. They are a natural aid supporting medical treatment for people of all ages.

Where should they be worn?

The insoles are intended for closed shoes with a covered heel. They can be used all season long, e.g. in low shoes, sandals, slippers with a covered heel, boots or sports shoes. The shoes should be loose – do not use the insoles in tight shoes, so as not to restrict blood circulation.

How do they work?

Used as shoe insoles, biothermal insoles shield the thermal energy of the feet. By reflecting heat rather than dissipating it, they influence the body's thermoregulation processes and, with them, microcirculation.

The insoles provide a thermal stimulus of low intensity and long duration. Under the influence of the thermal stimulus, the blood vessels dilate. These changes cause a significant increase in blood supply to the skin, which also affects the functioning of internal organs and the cardiorespiratory system and stimulates immune responses.

Using biothermal insoles raises the skin temperature of the foot, lower leg and thigh.

Has the effect of biothermal insoles been confirmed by scientific research?

Yes, the positive effect of biothermal insoles has been confirmed by scientific research carried out at the L. Rydygier Collegium Medicum in Bydgoszcz and at the Laboratory of Biotronics and Electrophotography in Kielce.

It is also confirmed by the opinions of doctors and insole users held by our company.
