Like each object used every day, even for the shoes, taking care of them helps to let last longer. The safety shoes require higher care in comparison to normal "walking" shoes. We use them for a longer time and even stress them much more. We wear them for at least 8 hours a day and for, at least, 220 days a year. We only have one pair of them while we, generally, more pairs of normal shoes. Some little cunnings and little daily care will allow your shoes to work with you for a longer time.
Newly bought shoes must be cleaned without too much energy. You might cause a colour loss.
Some old methods, heritage of our grandparents: use water and vinegar to remove stains caused by salt water. Oil is indicated against the stains caused by water and snow.
Our feet produce heat and moisture. When you finish working and take your shoes off, take out the footbed and let it dry.
Do not let wet shoes dry close to heat sources like radiators or stoves, because they would dry up and crack. Clean them with a wet cloth and dry them with a clean one. Otherwise you can let them dry in a aired place at room temperature. If possible use a tightener and leave them on one side.
If you work on dusty or muddy place, once you finish working remove all the rests, eventually sticked to the shoe and its sole.
