The Zoomlite shoe cube makes packing for travel even easier. It holds two pairs of shoes including socks. Keeps shoes together and other items in bag protected from dusty shoes. Can't travel with out it.

When you fly constantly and with the crack down on carry on travel luggage needs to be organised. Have previously purchased cheap ones which were not strong and had poor zips.
These are great...can be purchased separately in different colours and sizes.
Strong cases and good easy to use zips. Really helps keep travel bags organised. Mesh top so you can see whats in each if you not using the colour system. Bit expensive but will last.
