The product is a pair of Nike Air Huarache Aztec Grey running shoes, featuring a stylish a white main color with tan accents color. These sneakers are designed for unisex kids, with a size range of 5Y to 6/6.5 in women's sizing. With the popular Nike brand and comfortable Huarache model, these shoes are perfect for both style and performance for young athletes or casual wearers.

These are meant to fit snug as in a sock type sneakers so I would say it would definitely fit closer to a 5 1/2 to 6 versus a women’s 6 1/2. Great shoes!
