wrinkles on sneakers, anyone know how to get rid of or prevent?

I haven't done any research about that topic, but I don't think you can do something significant to prevent the wrinkles from occurring. I have the same problem, and if you have your sneakers made of leather, then trust me, wrinkles will be there just like wrinkles on our hands or faces. If you need suggestion, then maybe I would recommend you to use shoe polish to make leather more durable, but leather will still be leather, I am also worried about these wrinkles.

i haven't heard of products to prevent this thing.

to me, i guess we cannot prevent these wrinkles on the shoes to appear because we walk bending our foot and in the process, the shoes too.

i used to remember my late husband who was very keen on taking care of his shoes. when he arrives home and while watching tv after supper, he grabs his shoes and cleans them. before placing them on the rack, he inserts a mound of crumpled newspaper enough to fill in the hollow portion inside.

i think it was getting good results as his shoes look good even with age.

hope this would help ur problem. try it!
