Silver heel, outside of these are in perfect condition! I bought these for $125 at a vintage store without trying them on. They were marked as a 7, but I can’t find a tag on the shoe. I am normally a 7-7 1/2 and I was able to get my feet in, but couldn’t zip up ): my loss is your gain!! I would say because of the how narrow they are, these would be best for a size 6! The inside material is peeling very bad, but it doesn’t affect wearing the shoes, and the outside is undamaged!
