To buy: $15; amazon.com. “It was the perfect travel companion,” wrote one five-star reviewer who was actually able to pack two pairs of heels and three pairs of flip-flops inside. “It’s a lot roomier than I was expecting,” confirmed another shopper who said the bag “fits nicely” inside their carry-on. Not only can you fit multiple pairs of shoes inside a single Mossio shoe bag, but it’s also designed well: The entire bag is made from water-resistant polyester, and it has two-way zippers to allow you to easily open and close it. The bag also has a handle, so it’s easy to carry—and there’s even a travel sleeve on the back in case you decide to save space inside your suitcase and attach it to the outside of your luggage instead. “It’s so nice to no longer worry about putting dirty shoes in with my clean clothes or other items,” shared a reviewer who added that the bag “slid right over” their suitcase handle.
