PVC upper with wrap around ankle style. 5 inch heels. Size says 11 but they run small. I would say they would fit a Women’s US size 9 1/2 or 10. If you are a true 11, these are not the shoes for you.Size tag says 11 but listed as a size 10 because it will fit a size 10. The shoe you will get will have size 11 on it.
