Christian Louboutin Lady Peep 39.5

I'm selling my 100% Authentic Christian Louboutin Lady Peep 6" heel with 2" covered platform. Very comfortable. They fit a true size 9 foot. They are in excellent condition and have only been worn 3x. They do have a small grayish mark on the right heel and another the inside of the left heel. It's barely visible, but if it's a big concern please do not make an offer. Purchased online from Christian Louboutin website Nov 2016. Willing to trade for similar heel height & condition Louboutin in 39.
