Vionic Sandals for ladies. Sz 8 Brand new! Never worn!

The shoes are too big for my ankles. They are gorgeous shoes! But they need an ankle that measures around 12” in diameter. My ankles are just too small. The straps do stretch a bit so one who is 11-13” in diameter would be ok. But for comfort’s sake maybe it should be 11.5-12.5” diameter.
