So this tip is rather ghetto but I have to admit I did this just last week before a trip to New York. I wear my black pumps all winter long and by this time of the year they are in rough shape. However, with the nice weather right around the corner I'd rather by sandles that another pair of pumps.
So to get a few more uses out of them, I polished them and then used a black permanent marker to color in the knicks on the heals. From a distance they look nearly new and I was able to spend my money on these shoes instead!
