Tough Headphones Under My Rough Boots

I got a fresh pair of headphones and need to get rid of my old ones. I want to use my rough boots with deep tread and chunky high-heeled slippers to crush them - but theyre truly tough - standing on them and bending them doesnt do any damage at all. I need to grind my heels into them, stomp on them and jump on them to make them finally break apart!
