Shoes faithfully accompany us on all our adventures. We wear them every day and in all sorts of conditions and often take them off in the evening – maybe covered with mud and dirt if, for example, we have just come back from a hike in the mountains – and put them back on the shoe rack without taking care of them. Yet herein lies the secret to making shoes last a long time: maintenance and cleaning operations are essential to keeping their functional properties and quality intact over time.
