Nah, my shoes are safe (except the laces). Their revenge consists of throwing stuff from tables etc. and hide small things under the rug. I have a lego Saturn V. It was thrown onto the ground, now I sometimes fins pieces under the rug in the living room. There's dedication, the Lego set is upstairs in a spare room. But they also target spare keys from friends houses, my toothbrush once, pieces from a plate they threw off my kitchen counter and once they even stole my phone when I fell asleep on the couch, again neatly put under the living room rug.
