Step 1

 

• Use wire wool or sandpaper to scuff up the surface to create a key for the leather paint to stick to
  

Step 2

• Use white spirit to remove any polish residue
  

Step 3

• Use a cloth dipped in water and wash the boots all over making sure all traces of white spirit has gone.
  

Step 4

• Apply very thin coats of the leather paint, leaving each coat to dry, repeat until you have nice white layer. The trick to avoid cracks, is to use very thin coats, building up on layers. Paint each layer in a different direction i.e. 1st coat vertical, 2nd coat horizontal and so on...
  

Step 5

• If done correctly they should look like this and when walking the leather paint will not crack.
• Now, wear and tear on the boots may cause some of the paint (dye) to scuff or remove. You can purchase white scuff remover from most stores. Use this to touch up any marks. I also used scuff remover to paint the black fabric white.
