4.0Cancellation of the Guarantee shall occur due to:

4.1 – Defects caused by the incidence of chemical products capable of affecting the structure of the sole or the leather.
Note .: Except when the footwear has been specified for these purposes.

4.2 – Defects caused by natural wear and tear of footwear, as well as damages caused by improper conservation and/or hygiene of footwear.

4.3 – Defects caused by improper use, adulteration with components, repairs or replacement of components.

4.4 Defects caused by storage of footwear in hot and humid environments over a prolonged period of time, thus causing hydrolysis of the soles.

4.5 – Non-compliance recommended according to items 4.0 and 5.0.

5.0Recommendations for maintenance.

5.1 – It is necessary and of paramount importance to carry out maintenance in the following manner:

5.1.1 – Wash or wipe the shoes with a damp cloth at least once a week, and dry in shade.

5.1.2 – Perform periodic maintenance with greases, ointments, waxes for footwear or tallow.

5.1.3 – Keep footwear clean and dry to increase its useful life.

5.1.4 – Excessive moisture that penetrates in the footwear compromises its performance. It will be necessary to dry it with source of natural heat, in the shade.
Note .: The chemicals used in the shoemaking and leather tanning process are non-polluting.

5.2 – Cleaning guidelines in footwear in M.Micro:

Footwear in MMicro, for certain segments, shall be sanitized in a differentiated way due to the composition of this material.
This information contributes to the cleaning of the shoes, especially Fridges, which the inspection procedure implies, mainly, in the method how the footwear is sanitized.

5.2.1 – Always keep the antimicrobial insole dry.

5.2.2 – Keep your footwear in an airy place away from heat and moisture.

5.2.3 – Do not stock the footwear for a period exceeding 365 days to prevent the hydrolysis of the sole, if it is of polyurethane or rubber.

5.2.4 – Avoid the continuous use of the same pair of footwear to prevent the appearance of bacteria, fungus and bad smell. Let the footwear naturally eliminate the sweat absorbed, and if necessary, make your change every 6 months.

5.2.5 – Never let your footwear to dry near to sources of intense heat, such as clothes dryers, boilers, heaters, stoves, greenhouses, or even in the sun. High temperatures and attempts to accelerate the drying adversely affect the sole, hardening it and favoring its breakage due to loss of flexibility. The correct thing is the footwear to dry at room temperature and in the shade.

5.2.6 – The MMicro material shall be cleaned correctly, using hypochlorite at the appropriate product concentration, ideally at low concentrations of 1% and homogenized.

5.2.7 – In case of use of detergents, use products whose solution pH is neutral.

5.3 – Guidelines for hygienization of line 75:

5.3.1 – Sponge or brush of soft bristles;

5.3.2 Cleaning cloth;

5.3.3 – If the material is very dirty, it is necessary to apply detergent and water, but in small concentrations to avoid wear and damage of the color.

5.3.4 – Use a sponge, or brush for cleaning soft bristles, to rid the microfiber surface of minor scratches and dirt. Make circular strokes with the brush to gently wipe scuff marks and remove dirt.

5.3.5 – Avoid cleaning with water and also the use of shoes made in MMicro Sueder in environments with presence of humidity.

5.3.6 – If the footwear is difficult to remove, apply a special liquid cleanser for nobuck/suede or neutral detergent to remove difficult to remove and crusty dirt. Once the product has dried, rub the leather gently in small circles with a soft bristle brush or sponge to remove dirt.

6.0 – Recommendations for storage:

6.1 – Regarding the storage of footwear with polyurethane soles, we inform that it is not advisable to keep them in stock for an extended period of time, as this would require controlled environment temperature and humidity.

6.1.1 – This process occurs because the uncontrolled incidence of heat and humidity in the air form water molecules that begin to react with the chemicals that make up the polyurethane solder and cause HYDROLYSIS, which is technically the breaking of the polyurethane solder (PU), through the penetration of water (H2O), thus providing the decomposition of the sole.

6.1.2 – Leather is also not recommended for storage for a long time, once the dryness of its fibers begins to occur, with consequent damages of the product still in stock.

6.1.3 – For these reasons, as we do not know the storage environment of each customer, we recommend the footwear to be stocked for more than 01 (one) year.

6.1.4 – Regarding the storage system adopted, we suggest PEPS where the first product to enter the stock is really the first to leave, thus avoiding the aging of the footwear on the shelves.

7.0 – Technical Assistance:

7.1 – If the product has a defect due to a quality problem, it may be sent for technical analysis and, if necessary, we will make an exchange / repair. 89iuo0dcHowever, before being shipped to the factory, we recommend that you contact the technical staff to verify the real need for shipment and shipping procedures to the factory. Contact phone: 32-3693-4000/32-3693 4016.

Electrical insulation footwear, for example, provide protection for the service voltage for which 600 Volts have been specified and for voltage surges up to 14,000 V., but this guarantee shall be canceled if there are successive voltage surges, and it is necessary to replace the footwear of the user, if a first outbreak occurs.
Protective footwear can suffer premature wear through high temperature, chemical attack, damaged flooring, among others. Therefore, in areas where these factors are considerable, the durability is specific, varying the resistance of the footwear through the concentration and aggressive incidence of each area of the company.

For any additional information, we are available to respond.
