Daniel Green VTG 70’s VTG Embroidered Lamé Brocade Satin Slippers Floral Size 8

Daniel Green VTG 70’s VTG Embroidered Lamé Brocade Satin Slippers Floral Size 8 I measured in inches, 10.23” and centimeters is 26 cm long. On a shoes chart, that states a larger size. I am a size 9.5/10 and could not put my foot fully in. Therefore, I say they are size 8. The bridge is 3.5 inches long and quite narrow. I believe that is what is causing the sizing difference.
