Arvin olive sneaker fit in 6.5 US woman

I bought this shoes in January this year. Because I buy many shoes, I decide to sell this one. I always wear 6 but it’s my first time to buy this brand, so I buy it in 6.5 and it’s really for 6.5 person..... Anyway, I wear this no more than 5 times. Feel free to contact me if you have any questions!
