Christian Louboutin platform sling back sandals

Authentic Christian Louboutin sling back platform sandals. Size 38.5. New unworn condition. No box or dust bags. I bought these on Poshmark but unfortunately they don't fit me. I never wore them. I only tried them on. I'm asking to get back what I paid for them. No trades. No price reduction. Seller I bought them from on Poshmark had bought them and had the sole protectors professionally installed. Original price is what they had posted as well.
