Adidas Questar Flow K white/ blue size 7 youth/8.5 women’s

Worn only a handful of times. The soles are solid white so I didn’t have much luck keeping those white. However all the dust on the soles will wash right off with soap and rag. I’m a size 8.5 women’s but loved these shoes so I bought the youth 7. The color on the box says white/ blue but I feel like it’s more of a mint green than blue.
