My mom always makes this: grab
newspaper sheets, moistens with a little bit
of water and press them (the
sheets does not have to be super wet, they should be
just humidify), press hard and putting them very tight inside the sneaker / shoe, let pass a night like this and shoes will be a little bit larger.
What you want to do instead
of removing the pee pads completely, is
just remove the soiled
newspapers on top and replace with new
sheets of newspaper.
