Using these boots is simple. Just put them on like you would any other pair of shoes. When you're working, they'll give you great support and protection. As for the removable insole, if it gets dirty or you want to change it for a different type of comfort, just take it out and put in a new one. Here are some things to keep in mind. Don't expose the boots to extremely harsh chemicals as it might damage the materials. Also, make sure to tie the laces properly to get the best fit. For maintenance, clean the boots regularly with a soft brush and mild soap. Let them dry naturally. You can also apply a leather conditioner to keep the leather in good shape and prevent it from cracking.
