Natalia Blanco taupe suede open back bootie size 10 (41)

Natalia Blanco taupe suede open back bootie. Adjustable strap. Block natural heel. 100% suede leather. Made in Spain. Fantastic condition. Size 10 (41) I have seen different charts that mark this shoe size as anywhere from a 9.5 to a 10.5. I have done a rough measurement and the shoe is closest to the 10.1" range which conversion shows a size USA 10 (on the 9.5 side) Rough Measurement: 10.1" (see pic)
