Care guide for maintaining Alfa Air™.
In principle Alfa Air™ is a maintenance free material, but it is important to take care of shoes to maintain quality throughout the boot's lifetime. Dirt and moisture have little impact on well-kept boots.
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. For shoes with Gore-Tex® Surround is particularly important to let the shoes dry well, so that no moisture remains in the spacer.
Never stow away dirty boots. Remember to remove the laces before cleaning your boots. After removing the insoles and laces, remove any dirt. Average dirt levels require only luke-warm water, 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 sports stores.
We recommend lukewarm water and a little liquid dish soap with antibacterial properties to clean the inside of the boots. Use a soft brush to clean, rinse well and allow extended drying time (minimum a few days). This removes unpleasant odors from bacteria and salts that clog the membrane and therefore reduces the shoe's breathability.
After cleaning your shoes, they must be allowed to dry thoroughly before further treatment. It is best to put them at room temperature for 24 hours. After cleaning you shoes inside, they can be filled with newspaper for 30 minutes first to get out the most moisture.
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 (for Alfa Air™ this includes direct sunlight, as the material easily absorbs heat). Both leather and synthetic materials can easily be damaged from overheating, as they can shrink and lose their fit.
The outer material in Alfa Air™ is maintenance free and should not be treated with impregnation. In particular, we advise against using silicone based products, as they can cause discoloration of the outer material and will clog the Gore-Tex® membrane.
However, it is important to keep boots clean to not shorten the life of the shoe.
Store your boots at room temperature in a dry and properly ventilated place. Never store wet boots in moist rooms or in your car, as they are exposed to mold and discoloring. Furthermore, do not store them directly on heated floors, as it dries out the rubber and decreases the sole's lifespan.
Alfa Air™ should never be placed in direct sunlight as the material easily absorbs heat and can lose its fit.
