Adidas Falcon black on black running training sneakers metallic detail 6.5

Excellent condition! Like new, possibly worn once, very minimal signs of wear. Absolutely love these but they are a half a size too big for me (fit like a true 7.5 - adidas typically run a full size large). Hard to find black on black color! Willing to trade for a size 6. So comfy & trendy, go with everything! Questions welcome!
