Using these Keen Braddock Low Steel Toe shoes is easy. Just slip them on and start your day. When you feel your feet getting tired or the insole needs a change, you can simply take out the removable insole and put in a new one. As for maintenance, regularly clean the shoes with a soft brush and mild soap to keep them looking good. Avoid getting them in contact with harsh chemicals. Also, since they're not compatible with aftermarket insoles or orthotics, don't try to use any non - original insoles to prevent potential damage.
