A few words of caution on Saphir Cordovan Creme
-Some folks dislike the greasy finish it leaves behind
-It is not good for spot treating, it will change the appearance of the shoe a little, so use it on the whole shoe. Use wax for spot treating.
-Apply and work it in to small sections at a time. It dries fast, so if you try to apply it all over a pair of shoes, it will be too dry to go back and work it in where you started.
There is no one right/wrong answer to this question, or magic number of shoes that any individual should have. Personally, I like to have a lower number of higher quality shoes than an abundance of affordable shoes. I have 16 pairs of "nice" shoes. Meaning shoes that I try to keep looking good.
