Yo, I worn my regular Airforce all-white mid 10 times. I had it in my shoe cabinet for like a year. My whole Airforce is still cocaïne white, but I noticed my shoe tongue became a bit yellow :S. I Think it's a different kind of leather. Any way to fix this? P.S. I orderd Saloncare 40/12% and Angelus Sole Bright could they help?
