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.
