It's not always easy to protect your heels and other footwear while traveling, which is where Paravel's packing duo comes in. This set includes two organizers made from durable nylon crafted from seven upcycled plastic water bottles. A translucent top panel lets you always know which pairs are inside. The larger cube will hold tall boots or a few sneakers, while the smaller is sized for pumps and flats. You can also use them at home to store handbags, scarves and other accessories.
