To use these boots, simply slip your feet in through the round pull holes. They're great for everyday wear, work, or casual outings. When it comes to maintenance, use a soft brush to remove dirt after each use. You can also apply a leather conditioner every few weeks to keep the full - grain leather upper looking great and prevent it from drying out. Avoid exposing the boots to extreme heat or moisture for long periods. If the removable orthotic insole gets dirty, take it out and clean it separately. For the outsole, just wipe it clean to maintain its slip - resistant properties.
