The problem with my army of slippers, though, is that it exists out in the open and takes up space on my floor, even though it’s relatively tidy. The grip socks, however, can be stored in my drawer with other socks and hidden away. They’re also perfect for travel: Why waste suitcase space on slippers for padding around a bed-and-breakfast when these comfy socks take up just two inches when folded? I’d also consider tossing them in my bag to bring with me to a friend’s shoes-off house or providing a few for when my own guests come over.
