BCBGeneration BG- Marisol Knee High Golden Brown boots

I bought these boots on an online platform as used like new and even though they say they are a size 8 1/2B / 38 1/2 and I normally wear a 7.5 they are just barely too snug for me. It may just be they are stiff and need to be broke in but I would say they are closer to a size 7.5. The circumference is 16 but opens up another inch or better with hidden elastic band. See pictures. Nice looking boot!
