To wear these booties, simply slide your feet in. They're great for various occasions, from casual outings to semi - formal events. When it comes to maintenance, use a soft cloth to wipe off dirt regularly. Avoid exposing them to extreme heat or moisture. If the leather gets wet, let them dry naturally away from direct heat. You can also apply a leather conditioner occasionally to keep the waxed leather in good condition. As for the removable insole, you can take it out and clean it separately if needed.
