To use these shoes, simply adjust the hook - and - loop straps according to your comfort. Put them on just like any other pair of shoes. When it comes to maintenance, use a soft brush to clean the nubuck leather upper gently. Avoid getting the shoes wet as much as possible. If they do get wet, let them dry naturally away from direct heat. For the removable footbed, you can take it out and air it regularly to keep it fresh. Also, store the shoes in a cool, dry place when not in use.
