Safety-relevant features which have to be considered according to BGR 191:
If you use any insole other than the standard checked one, the following parameters which have to be fulfilled according to EN ISO 20345 could change:
When adjusting safety shoes orthopedically, the following parameters which have to be fulfilled according to EN ISO 20345 could change:
After the orthopedic modification, the parameters still have to comply with EN ISO 20345.
Damit Sie sich bei der Arbeit mit Sicherheit wohlfühlen, haben wir unsere Sicherheitsschuhe nach dem Baak Wohlfühlkonzept entwickelt. Dieses Konzept beinhaltet folgende Aspekte:
Komfort, Schutz und Technologie
Diesen Komfort können Sie spüren.
Dieser Schutz bietet Ihnen Sicherheit.
Dieser Technologie können Sie vertrauen.
Um Ihnen die Auswahl unserer Baak Modelle zu erleichtern, haben wir bei den einzelnen Serien diese drei Aspekte besonders übersichtlich dargestellt.
More and more companies trust in protection by ESD safety shoes. ESD is the only protecting feature of safety shoes which is not only designed for the safety of the wearer but also for the protection of your products.
Each of us “gets a jolt“ from time to time when touching a doorknob, other people etc. The reason is that you were charged electrostatically, for example while walking on a carpet. But sometimes the “friction” of your body at the air is sufficient. If you come close to an uncharged or differently charged object, a spontaneous discharge takes place, comparable to a mini-lightning. Human beings feel those discharges starting at a voltage of about 2,000V. Each of us causes small discharges every day, but they are not perceptible because most of them are considerably below 2,000V.
But if you are in touch with an electronic element, it might even be damaged due to the non-perceptible discharges. Besides this damage, the of this element could decrease, and as a consequence, your claim rate might raise.
But also in areas with an increased danger of fire or explosion, electrostatic discharges have to be avoided. They could fan flames or spark explosive gases.
There are various possibilities to avoid uncontrolled electrostatic discharges. Probably the most practical and flexible one is to wear ESD shoes on a grounded floor. The target is to be charged with a voltage at a maximum of 100 volts (currently recommended limit). Of course, your clothing and your entire workplace should have ESD properties, too.
During the last years, Baak has become an ESD specialist. We are in constant information exchange with producers of ESD (measurement) products, certification institutes and acknowledged ESD experts. We have reached our goal to be an ESD specialist due to hard detail work. Besides the regular safety properties, all Baak safety shoes have been optimized in detail regarding their ESD ability, e.g. by electrostatic boards and insocks. That is why the recommended discharge resistance is certainly always fulfilled, even if there is only a partial contact of the sole to the grounded floor.
Recommended discharge resistance of the unit human/shoe/floor (ESD):
100 kOhm – 35 MOhm = 105 – 3,5 x 107 Ohm
|103 Ohm = 0,001 MOhm = 1 kOhm|
|104 Ohm = 0,01 MOhm = 10 kOhm|
|105 Ohm = 0,1 MOhm = 100 kOhm|
|106 Ohm = 1 MOhm = 1.000 kOhm|
|107 Ohm = 10 MOhm|
|108 Ohm = 100 MOhm|
|109 Ohm = 1.000 MOhm = 1 GOhm|
With safety shoes from Baak, you don´t have to waste any more time thinking about ESD. Better keep an eye on other subjects, such as:
Laboratory test according to DIN 61340 – 4 – 3
There is only one parameter in the norm which must be complied with. The discharge resistance of a shoe is determined using pebble beds; the resistance of one shoe must be between 100 KOhm and 100 MOhm.
Workplace test according to DIN 61340 – 5 – 1
But in practice it is the resistance of the unit human/shoe/floor which is relevant. This can be evaluated by different methods of measurement (single/parallel measurement), set to different, individual limits.
In the workplace test according to the standard, the recommended discharge resistance of the unit human/shoe/floor should not exceed 35 MOhm.
We would like to optimize our know-how for you, therefore we depend on your help. The more information we get from companies about their measuring methods and limit values, the better we can adapt our developments to the requirements in the practical use.

Thank you very much.
Dependence on the climate
The electrostatic charge and discharge depend strongly on the air humidity and thus on the climate at the location. The lower the air humidity,the lower the discharge. At the same time, the charge increases strongly at a low level of air humidity.
The laboratory test (DIN 61340 – 4 – 3) is classified into 3 climate categories:
In all 3 classes, the discharge resistance levels must be the same; the classes only differ in the air humidity.
|Produced charge at air humidity|
|Source||10–20 %||65–90 %|
|Walking on a carpet||35,000 volts||1,500 volts|
|Walking on linoleum||12,000 volts||250 volts|
|Work at a work bench||6,000 volts||100 volts|
|Paper in plastic bag||7,000 volts||600 volts|
|Kunststoffbeutel||20,000 volts||1,00 volts|
|Upholstered chair||18,000 volts||1,500 volts|
State-of-the-art safety shoes
Baak is an expert on safety shoes that are optimally suited to the foot. The company's own product development department keeps doing research on the latest technologies, materials and ideas for the sake of those who wear safety shoes. For example, Baak was the first safety shoe manufacturer to identify the excellent benefits of a lightweight, damping sole material from the running shoe sector and introduced EVA into the safety shoe industry with great success.
To keep improving our competence in optimally suited safety shoes, we also like to cooperate with experts from neighbouring disciplines. For example, we developed the Baak® go&relax system in cooperation with one of the world's leading biomechanists, Prof. Dr. Gert-Peter Brüggemann.
For Baak, a functioning quality management system plays an important role. The quality of the raw materials, the individual shoe parts and the finished safety shoes is controlled permanently. This is done by specially trained Baak staff at the production sites and, of course, also at the incoming goods department.
Are you interested?
The key to success is interdisciplinary collaboration. Worldwide, Baak develops shoes in cooperation with many specialists, e.g. from the sports shoe industry, shoe orthopedics and biomechanics. The aim: With this know-how transfer, we want to keep on expanding our advantage in technology for the good of the safety shoe wearer.
The main task is the long-term maintenance of the wearer’s health, considering the individual requirements in his job. As a safety shoe expert, Baak is, of course in permanent exchange with specialists of various specific areas, such as ESD, the supply industry, testing and certificating institutes. And since its foundation, Baak has been a member of the German Standards Committee (Deutscher Normenausschuss).
We are especially delighted about the collaboration with Prof. Dr. Gert-Peter Brüggemann who stregthens our competence team “Feel good at work”.
Natural and functional foot load distribution
The shapes of the Baak® flex cap and the Baak® flex zone in the outsole are optimally suited to the foot and based on the natural bending line of the basic toe joints. Therefore, a safety shoe with the Baak® go&relax system, unlike a common safety shoe, bends in a way that is optimally suited to the foot's function. The foot is able to move in a natural and biomechanically correct manner. One of the world's leading biomechanists, Prof. Dr. Gert-Peter Brüggemann, was involved in the development of the Baak® go&relax system to a considerable extent.
Always stay fit
The Baak® go&relax system distributes the load optimally over all muscles and joints involved – with every step. The feet, muscles and joints stay fit. That relieves pressure on the entire musculoskeletal system. Unequal load distributions are prevented successfully. Walking is really comfortable. A shoe should always allow the foot to do what it wants to do naturally. Therefore, for people who wear safety shoes for many hours a day, a natural and functional foot load distribution is of particular importance. A useful contribution to company health management.
"A natural and functional foot roll in the shoe makes a contribution to the health of the foot, muscles and joints. It releases the whole musculoskeletal system" says Prof. Dr. Brüggemann.
