Authentic Christian Louboutin Simple Pump 100mm Patent Leather Calf in Nude Size 39 is equivalent to US 9 per Christian Louboutin website, however, Louboutins run small, so it is recommended to size up 1/2 - 1 size. I wear a women's US 7.5-8 and these fit me perfectly! Timeless round-toe silhouette in patent calf leather 3.3" heel Leather lining Signature red leather sole Padded insole Slip on Shoes are in incredible condition as they have only been worn once: Very light scuffs on soles and no damage to outer parts of the shoe. Christian Louboutin box and protective bags can come with the shoes if you want, however, the box is for a different pair of sneakers I purchased!
