Letter of Guarantee and Recommendations

This Warranty Letter outlines Marluvas' commitment to its customers to replace footwear that exhibits manufacturing defects, provided they meet the terms described below and the defects are duly verified by the Marluvas Technical Laboratory through a Physical and Chemical Testing Report.

The validity and warranty periods vary by product line, as shown in the following table:

Important: The validity, according to Technical Note 146-2015 CGNOR, corresponds to the maximum period during which the footwear can be used. This period begins to be counted from the manufacturing date engraved on the product and represents the deadline for the effectiveness and quality of the footwear in use, provided that the handling and storage instructions are followed.

Important: The product warranty begins upon the effective delivery of the product, considering the issuance of the Invoice, in accordance with paragraph 1 of article 26 of the Consumer Defense Code.

The supply warranty against manufacturing defects for sugar and alcohol plants and agricultural areas, in lines 50/60/70 in split leather and M.Micro, is 180 days. Other lines do not have a warranty for these applications, due to the aggressiveness of the area and the effects of sucrose.

Footwear used in steelmaking areas has a warranty of 180 days.

Footwear used in refrigerated warehouse areas has a warranty of 180 days.

For antistatic footwear, regarding dissipation, the warranty is 180 days.

The warranty will be voided due to:

3.1 Defects caused by chemical products capable of affecting the structure of the sole or upper of the footwear. In these cases, an analysis of the SDS of the product used is required.

Note: Except when the footwear is specified for this purpose.

3.2 Defects caused by natural wear and tear of the footwear, as well as damage caused by poor maintenance and/or improper cleaning.

3.3 Defects caused by improper use, alteration of components, repairs, or component replacement.

3.4 Defects caused by storing footwear in humid and hot environments for prolonged periods, which may lead to sole hydrolysis.

3.5 Non-compliance with recommendations as per items 3.0 and 5.0.

4.1 It is necessary and of utmost importance to carry out maintenance in the following manner:

4.1.1 Wash or clean the footwear with a damp cloth at least once a week and dry in the shade.

4.1.2 Perform periodic maintenance with grease, polish, shoe waxes, or tallow.

4.1.3 Keep the footwear dry and clean to increase its lifespan.

4.1.4 Excess moisture that penetrates the footwear compromises its performance. In this case, it will be necessary to dry it with a natural heat source, always in the shade.

Note: The chemicals used in the footwear construction process and leather tanning are not contaminants.

4.2 – Cleaning guidelines for M.Micro footwear — Lines 65 and 70

M.Micro footwear, for certain segments, should be sanitized differently due to the composition of this material.

This information sheet contributes to the cleaning of footwear, especially for cold storage facilities, where the inspection procedure mainly involves the footwear sanitation method.

4.2.1 Always keep the antimicrobial insole dry.

4.2.2 Always keep your footwear in a well-ventilated place, away from heat and humidity.

4.2.3 Do not store footwear for more than 365 days, to avoid hydrolysis of the sole, if it is made of polyurethane or rubber.

4.2.4 Avoid continuous use of the same pair of shoes to prevent the appearance of bacteria, fungi, and odor. Let the footwear naturally eliminate absorbed sweat, and if necessary, replace it every 6 months.

4.2.5 Never let your footwear dry near intense heat sources, such as clothes dryers, boilers, heaters, ovens, stoves, or in the sun. High temperatures and attempts to speed up drying negatively affect the sole, hardening it and favoring its breakage due to loss of flexibility. The correct way is for the footwear to dry at room temperature and in the shade.

4.2.6 The M.Micro material should be cleaned correctly, using hypochlorite at the appropriate concentration. It is ideal to use low concentrations, of 1%, with the product homogenized.

4.2.7 If using detergents, use products whose solution pH is neutral.

4.3 – Guidelines for sanitizing lines 75 and 50B26 — Nubuck

4.3.1 Use a sponge or soft-bristled brush.

4.3.2 Use a cleaning cloth.

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

4.3.4 Use a sponge or soft-bristled brush to clean nubuck leather, removing scratches and light dirt. Use circular motions to gently clean marks and remove dirt.

4.3.5 Avoid cleaning with water and also using footwear made of nubuck leather in humid environments.

4.3.6 If the footwear has dirt that is difficult to remove, apply a special liquid cleaner for nubuck/suede or neutral detergent. Once the product dries, gently rub the upper, in small circles, with a soft-bristled brush or sponge to remove the dirt.

4.4 – Guidelines for sanitizing leather lines

4.4.1 Leather footwear should be cleaned with a cloth slightly dampened with water on the outside. On the inside, it is recommended to use a cloth with alcohol for sanitization. Insoles can be removed and hand-washed with water and neutral soap.

4.4.2 If you choose to use any product during cleaning, choose only specific products for leather, applying them with the aid of a natural or synthetic bristled brush.

4.4.3 Footwear should be dried at room temperature and in the shade, in cool and well-ventilated places. It is important to avoid exposure to intense heat, as this can harden the sole, compromise its flexibility, and favor the appearance of cracks.

4.5 – Guidelines for sanitizing textile upper

4.5.1 To clean fabric footwear, use a soft-bristled toothbrush and choose products such as vinegar, neutral detergent, or baking soda, depending on the type of dirt to be removed.

4.5.2 Another option is to wash the footwear with pH-neutral soap, ideal for eliminating stains without damaging the fabric.

5.1 Regarding the storage of shoes with polyurethane soles, we inform you that it is not advisable to keep them in stock for prolonged periods, as this would require maintaining controlled temperature and ambient humidity.

5.1.1 This process occurs because uncontrolled heat and air humidity in the storage area form water molecules that begin to react with the chemical products that make up the polyurethane sole, causing hydrolysis. Technically, this is the breakdown of the polyurethane sole due to water penetration, leading to its decomposition.

5.1.2 For leather, long-term storage is also not recommended, as its fibers can dry out, leading to damage to the product while still in stock.

5.1.3 For these reasons, and because we are unaware of each client's storage environment, we recommend that shoes not be stored for more than 1 year.

5.1.4 Regarding the storage system adopted, we suggest FIFO (First-In, First-Out), where the first product to enter the stock is the first to leave, preventing the aging of shoes on the shelves.

6.1 If the product presents any defect due to a quality issue, it is extremely important that it be sent for technical analysis, in order to validate the defect and the complaint. If necessary, it will be replaced or repaired. However, before sending it to the factory, we recommend contacting the customer relations team to verify if shipment and the shipping procedures to the factory are actually necessary.

6.2 On-site technical assistance is required in the following cases:

6.2.1 Work accident.

6.2.2 Premature wear of footwear, exceeding 50 pairs.

6.2.3 Preventive visit, to recommend the ideal footwear for large construction projects.

For example, electrical insulating footwear offers protection for the service voltage for which it was specified, 500 volts, and for voltage surges of up to 14,000 V. However, this guarantee will be voided if successive voltage surges occur, requiring the user's footwear to be replaced after the first surge.

Protective footwear may experience premature wear due to high temperatures, chemical attack, damaged flooring, among other factors. Therefore, in areas where these factors are considerable, durability is specific, varying according to the concentration and aggressive incidence of each company environment.
