Fit Tip: Shoes are listed in US sizes. adidas unisex styles follow approximately a 1 size difference between men?s and women?s sizing. If you are between sizes or prefer a roomier fit, consider going half a size up. Always compare your foot length (heel-to-toe in cm) to the chart above for best accuracy.
