Protective footwear most often is intended for the protection against several kinds of dangers at the same time. The basic task of the protective footwear is the protection of feet and legs from mechanical or chemical damage and also burns, harmful influence of low and high temperatures as well as wetness.
Protective characteristics depend most of all on the materials used in production of footwear as well as the construction and the possible accessories, such as puncture resistant insoles, ankle protections etc.
Providing adequate legs protection has a crucial impact on the safety and comfort of a worker moving in a workplace.

Static electricity is a common, polysemic term for electrostatic charge as well as the phenomena of its creation, accumulation and dissipation.
A specific form of electrostatic charge dissipation are electrostatic discharges (ESD) - short electric impulses appearing in the space between objects of sufficiently big difference of electrostatic potentials, which lead to full or partial dissipation of the electrostatic charge from those objects.
Because the discharges last relatively short time, from several dozens of nanoseconds to several hundreds of microseconds, created impulses are very strong, enough to ignite explosive atmospheres, shock workers, damage solid state devices. Electrostatic dangers are understood as potential possibility of occurrence of the abovementioned electrostatic discharge effects.

The effects of electrostatic charge build-ups are especially severely felt in winter, in unconditioned, centrally heated rooms, when the relative air humidity, in extreme conditions, fall down to a dozen or so percent. Such conditions, as the result of a significant increase of material electric resistance, reinforce the creation of electrostatic charges and maintaining the state of electrostatic charge build-up by a particular material or object. Among others, inappropriately chosen personal protective equipment has a large influence on the level of the danger occurring in the work environment. On the one side, it can inadequately protect human from external impact of static electricity, and on the other side, it may cause dangerous electrostatic charge build-up of the human body.*
The footwear protecting from the ESD effect allows to prevent electric charge build-up of a person wearing footwear e.g. as the effect of friction while walking on certain surfaces, thus it prevents dangerous electrostatic discharges. On the other hand, if electrostatic discharge happens or a worker has a contact with high voltage, it is thanks to the resistance of minimum 0,75 MΩ that the results are mitigated.
ESD footwear should be used when there is a necessity to prevent electrostatic charge build-up of a worker by discharging static electricity. The presence of the factors such as climate, dirt, material properties, surface resistance, shoe design either aggravates or enhances the properties of ESD shoe.
Feet are a very important part of human body. The specialists confirm that there are about 7000 receptors, which are responsible for particular body organs, placed on feet. This is why healthy feet are so important for overall health and well-being.
Deformed feet can cause spinal problems and even changes in knee or hip joints. Feet ailments can also be the reason of an inappropriate gait, which in the effect can have a bad impact on the health of the internal organs in the pelvis area.
An effective way to take care of the feet on daily basis is using appropriate insoles.
terry zone, which occurs in the construction of many models of socks, which are intended to be worn at different temperatures. Both those higher and those very low.
The purpose of this layer is damping the pressure on the Surface, protection against abrasion, in the case of models which do not contain fiber Coolmax its composition also thermal insulation. The models that are worn in the summer terry layer is combined with a special, breathable and anti-bacterial composition (Coolmax, Natural Cotton, Amicor or Prolen Siltex).
All of these models are suitable for long-term wear for people who work in extreme field conditions (eg. building), or intensely active in sports - terry layer protects the foot and composition guarantees breathable and antibacterial qualities.
non-compression double welt provides high comfort.
a system of ventilation ducts helps to maintain optimal air exchange draining the moisture and excess of heat outside.
triple weave of „3D” fibers absorbs foot pressure on the surface.
heel „Y” type, respectively shaped knit perfectly fits to the foot and stabilizes the foot in the shoe.
flat seam at the toes prevents chafing and provides comfort of use.
additional welt on the midfoot stabilizing the sock on the foot.
The selection of suitable socks can greatly increase comfort at work and in everyday life. Advanced technologies used in the manufacture of materials and socks make the feet are less tired and better cared for.
Fabrics used in socks:
technical fiber to ensure moisture away from the body, provides long-term air circulation and dryness, protects the foot from chafing.
yarn modified with an antibacterial agent based on biogenic ions of silver (Ag +), inhibits the growth of bacteria, fungi and mold, reduces odor, maintains biological balance of the skin, provides a long-lasting feeling of freshness, is safe for the user and the environment.
technical fiber responsible for antibacterial and antifungal properties, it contains a formulation to prevent the growth of bacteria responsible for odor of sweat and a mix of preparations disposing of microorganisms that serve as food for mites.
natural cotton guarantees wearing comfort, high strength, excellent thermal insulation, dryness, skin breathing alloys and hypoallergenic qualities.
natural merino wool ensures excellent thermal insulation, long-lasting feeling of dryness and provides respiration of the skin.
fiber with technical properties, has a very high tensile strength and thermal performance, guarantees the size stability and high resistance to wear.
modern fiber for thermal qualities, provides the ideal thermal comfort at extremely low temperatures, while helping in draining moisture outside the sock.
