Before they are worn for the first time, new shoes should be given a basic waterproofing treatment to protect them against deeply engrained dirt and penetrating moisture. Waterproof each shoe uniformly two to three times from a distance of 20 cm.

Use a COLLONIL waterproofing spray suitable for the type of material. In no case the application shall be too wet. Instead, apply the spray thinly several times. After a sufficient drying period, smooth leather can be polished and suede leather can be roughened.

The long-term efficacy of any waterproofing treatment is reduced by mechanical strains during walking as well as by climatic effects. Therefore, depending on the frequency of wear and strain, leather should be retreated with a waterproofing product regularly. Upper materials and leather soles alike should be treated regularly.

Because leather loses its nutrients and oils through regular use, causing it to become hard and brittle, it is advisable to use a COLLONIL care product regularly. We recommend the coloured care products for colour enhancement. Leather should be cleaned depending on its type and soiling. Cleaning should always be carried out at regular intervals before waterproofing and care. Always try dry cleaning first because this is not so hard on the leather. Damp or wet cleaning is advisable for stubborn soiling. Afterwards renew the waterproofing and treat with a care product.
