Mexican Huarache sandals

I bought these in Huatulco, Mexico and after getting home realized that they’re just too small. I wear a “large” 8.5 (so sometimes a 9) and they’re ok for a little while, then I have to take them off! They have never been worn outside. I absolutely love them, but I can’t wear them 😞 The outside of the sandal measures approximately 26.5 cm or 10 3/8” I think someone who wears an 8 to a “small” 8.5 will probably be fine with them.
