The first thing to do is place a shoe tree in each shoe to help them keep their shape and smooth out creases. If you don’t have shoe trees, stuff them with newspaper to absorb humidity and stretch the leather upper.
Once you’ve done this, clean smooth leather with a damp cloth to remove dirt, get rid of old polish and prepare it for the products you’re about to apply. Don’t forget to rub the welt with a special brush to eliminate dust and dirt.
Once your shoes are clean and before you begin polishing them, it is important to moisturise them using a moisturising cream (renovating milk?). This will help the leather retain its elasticity and stay naturally in good condition.
