are there any household items i can use to dye my sneakers?

i have two white stripes on my black sneakers that i need to make black. can i just color the white stripes with a black marker? or use black nail polish? any tips would be helpful thanks!

It may depend upon the type of fabric used to construct the sneakers, but I've used a sharpie on dress shoes before and it worked.

Sharpie

Go to the store and buy some black shoe polish
