The shoes work as advertised, but the white color is a magnet for dirt. I had used a coating of Scotch Guard to try to help in being able to service the shoe without wasting time trying to wash the 'dirt off the white' shoe? Perhaps you could apply a coating of something just like Scotch Guard does, I won't spend so much just replacing the shoe vs. being able to clean them? Please provide any good new on this topic? Thanks.
