ASOS gold sandals, size 9/9.5

Sexy ASOS gold tone high-heel sandals with wide ankle strap. Size is nowhere to be seen. My best guess is between a 9 and 9.5. *The length of the footbed on the inside from back of heel to tip of toe edge is exactly 10 1/8”. I am an 8.5 and they are too big by about 1 size. The inside measurement of strap at the front is 4 1/2”. Heel is 4 1/4” high. In great condition with very little signs of wear.
