Thanks for the tutorial, I have been wearing white shoes for 20 years and constantly get them dirty. I am so used to wearing white sneakers, sneakers, even tried to find shoes in white (I understand that this is not elegant in a classic style). On weekdays, I prefer to wear white walking boots , and of course when we go out with his family on nature, I put on sneakers. After a picnic in nature, white sneakers get very dirty. So I bought new sneakers every month, because it is impossible to bleach them. Heh... Thanks to your method, I will save some money.
