Using these Keen Braddock Low work shoes is simple. Just put them on like any other pair of shoes. They're designed to keep your feet comfortable during long work shifts. When it comes to the removable insole, you can take it out and replace it to support your arches better. Remember, these shoes are not compatible with aftermarket insoles or orthotics. For maintenance, keep the shoes clean. You can use a soft brush to clean the nubuck leather upper. To dry them, avoid direct heat sources; instead, let them air - dry naturally. This will help maintain the waterproof feature of the leather. Also, the Cleansport NXT™ technology helps control odor, but it's still a good idea to let the shoes air out after each use to keep them fresh.
