Banana Republic review: new flyknit sneakers neonyellow 457765-00-1 0009

I purchased these sneakers on 6/27/19. I wore the sneakers on Saturday evening 8/4/19. I unfortunately got caught in the rain so my sneakers became dirty. I decided to wash them alone and air dry them. I'm disappointed because when I pull them out of machine they were spectacularly white. When they dried the white of the sneakers turned yellowish-brown.
