OK - I know how to take care of shoes...but am a little stumped with shoes such as the Allen Edmonds McTavish (pictured below) because of the contrasting stitching. I wouldn't want to put cream on them as I feel the cream would dye the stitching - same as polish. I would also be nervous brushing them for the same reason. Anyone have any suggestions? Anyone have these and take care of them a specific way? Love the shoes - just want to take care of them and preserve the look.
