The same exact job will be done by a thick Posca marker. Tested, it does not fade and it lasts until you repaint it.

Basically, it is a white paint and not so much a cleaner. Now, as for the price, I would say it should be around 10 euros.

I tried them all out of curiosity. None of them do the job. These specific markers, if you try to clean your shoes, they just repaint them afterwards. What else can I write? Just a waste of money.

Very good, it mostly dyes and brings back the color but it does an incredible job.
The shoes had yellowed and couldn't be cleaned with anything. With 2 good coats, they became like new.

It was used on the Nike Vapormax Plus. It does its job just fine. I had tried with a regular marker before getting this one. Much better.
