KEEP SHOES CLEAN
KEEP SHOES DRY
After you have worn your shoes, put them in a dry place. You can also put some newspapers inside to make the drying process faster. This way the humidity would get into the paper.
DO NOT place them near the heater, radiator and never dry them in unnatural way, for example with a hair dryer. Shoes are made entirely from the leather and the heat may change the shape of the shoe.
DO NOT place them in a plastic or any other bag, which does not have a good air circulation. If the shoes are wet this may cause bad odour.
