I have some Alden Shell Cordovans in color 8. Every website I see says to use a different color polish. However, Alden makes their own polish in a color 8 ( I assume, and hope, Saphir actually makes it). Since Alden makes the shoe, I would presume that would be the best. Any thoughts on what color, or colors, will provide the best patina for the shoes? Thank you all in advance.
