Keep your footwear options open when you travel with this Spacepak Shoe bag from Flight 001. Perfect if where you're headed is different than where you are! This small shoe bag was designed to fit in your carry on bag and allows for ultimate compression using air vents on the side. Easily squeeze out extra air that makes your airline luggage bulky and less functional. You can carry one pair of hard shoes and one soft pair (like flats or flip flips), so, when you do the math, you can take a max of three pairs of shoes (including the ones you're wearing)! How can you say no to a Spacepak Shoe bag?
