Since white sneakers get dirty very easily, do you guys use those sprays?
White sneakers do indeed get dirty very quickly - I have a pair of brilliant white Lacostes which I thought would never stay clean.
However, I would never
use any kind of dirt repellent myself - after all, trainers are supposed to get muddy, almost (unlike the rest of your clothes, having a bit of dirt on your trainers is seen as almost a good thing.) And you'll be surprised by actually how hard it is to get mud to stick onto the trainers - the only time I've ever had to wash them was when I went through a muddy field, and even then it wasn't that bad. In fact, speaking of washing, if you get your white trainers a bit dirty one day just stick them in the washing machine and they should always come out sparkling like new
