The insoles absorb plenty of moisture and should be removed after every longer trip, as they will dry quickly when outside of the boot. This is especially important after multi-day excursions.
Cleaning boots in textile / synthetic materials
Never stow away dirty boots. Remember to remove the laces before cleaning, brushing and/or polishing your boots. After removing the insoles and laces, remove any dirt from the upper. Average dirt levels require only brushing, luke-warm water and dish soap, which can also be used to clean the sole and sole rim. Very dirty boots must be treated with custom cleaning products developed specifically for shoes. This type of product can be found in well-assorted shoe and sports stores.
To avoid wet shoes on your next trip, it is important to thoroughly impregnate the boots to close the pores and restore their water-repellent properties.
Drying textile / synthetic shoes
Shoes in general do not tolerate high heat and we recommend using drying temperatures below 37°C. Do not place the shoes on or close to a radiator, fireplace or other heat source. Textiles and other synthetic materials can easily be damaged from overheating, as they can shrink and lose their fit.
Impregnating textiles and synthetic materials
Cleaning products open the pores of the boot material allowing them to easily absorb water. Use impregnation to close the pores. Proper impregnation prevents water absorption while maintaining breathability. Layer the impregnation in two layers and let it dry between and after each layer.
How often should I treat my boots?
The frequency of impregnation depends on the amount of use. A rule of thumb is to look at the boots; when they begin to absorb water and darker spots appear on certain points, like the instep fold, it is time for proper care. Before longer excursions, it is recommended to thoroughly treat the boots. Properly maintained boots will repel water, rather than bleed into the material.
Remember that proper care significantly prolongs the lifespan of your boot
