Adidas gazelle indoors collegiate green hazy sky blue gum

Just bought these but they are too big on me… willing to swap for a smaller size! These still have the tags and box. ****please read re sizing*** These are men’s US 7.5. According to the adidas website, the women’s equivalent is US 8.5. These would best fit a women’s 9 or maybe 9.5! It’s almost a whole inch too big on me and I’m an 8.5
