Mexican Huarache leather sandals light brown 8.5-9

Read carefully: Light brown leather Mexican Huarache sandals. Purchased in Mexico, brand new never worn. I am a true 8 and like my leather sandals to fit just right as they stretch and form to your foot. I believe my feet must have been swollen when I tried these on because now they are way too loose. It is written as a Mexican size 6 on the bottoms. I think these would be perfect for an 8.5 as they will stretch to fit. Maybe a 9? Sold as is.
