I never wore this out into public. The residue on the bottom is from the stickers that were on them. I attempted to clean them up to remove the sticky- but just managed to spread it into the grooves. Traditional Versace Medusa slides. I hurt my foot and can’t wear these or I’d keep them. Retail: $395 No box. No dustbags. Please ask any questions you may have. I want you to be satisfied with your purchase. Thank you for checking out my closet
