Lifting your foot you see a tiny red brick stuck to the bottom: a present from Satan himself.
Suffer no more, now that Lego has unveiled the newest accessory in its popular line of buildable bricks and minifig characters: Lego slippers that have extra padding to protect feet from tiny bricks.
The sad news: Only 1,500 will be made, and they aren't for sale.
Instead, Lego will be giving away the pain-preventing slippers (while supplies last) to people who make a Christmas wish list on the Lego France website.
While kids may beam with joy to unwrap 3,000 new pieces for their mega-spaceship, parents can rest easy their soft soles aren't in any danger.
Whatever you do, don't blame Lego. Their products are just starting to inspire a new generation of women in science, technology, engineering, and math.
