These are amazing! The contrast between the light beige and dark blue is striking. Leather sole, leather sock lining (heel area shows a tad of wear), strap that is reinforced with leather over the perforations, and a 3.75” heel tops off this collection shoe. It appears to be silk to me. I cannot find a comp for this exact shoe so it is a bargain as similar others run much more. Fits like a true Size 9.
