Using these Wolky Chili Mary Jane shoes is easy. Just adjust the Velcro closure to fit your foot comfortably. The shoe is suitable for daily wear, whether you're running errands or going out for a casual walk. When it comes to maintenance, it's best to clean the leather and nubuck parts regularly with a soft brush or cloth. For the leather, you can use a leather cleaner and conditioner to keep it soft and supple. Avoid getting the shoes too wet as this can damage the materials. If they do get wet, let them dry naturally away from direct heat. Also, since the footbed is removable, you can take it out to air it and keep the shoe fresh. When choosing the size, keep in mind that the measurements may vary, so it's a good idea to refer to the size chart. And if you have a fuller foot, the width size W should be a good fit for you.
