The mac method described here http://theagatineeyelet.wordpress.co...he-mac-method/ Basically, brush them. A lot. And then brush them some more. This method works well. Before each wear I typically wipe mine with a damp rag then brush and buff vigorously. Consistent with the mac method, I apply a thin coat of wax after about a dozen wearings. This type of maintenance makes shell good for travel when I only want to take one pair of shoes. I don't have worry with bringing polish along or be too concerned with wearing the same shoes daily.
