I bought a Lady Lynch from http://us.christianlouboutin.com/ and I sold it on ebay last week. I do have the receipt and order confirmation that was sent to my email. I did note that I replaced the sole with vibram rubber sole that has the same red color as the Louboutin red sole, but she accused me of selling fake Louboutin! What should I do to prove her that this is an authentic Louboutin? Should I ask the ladies from the authenticate this Louboutin thread to re-authenticate the shoes to reassure the buyer, although I clearly bought it from Louboutin boutique?
