current shoe bags and shoe covers

Most shoe cover manufacturers use cotton, fleece, or nylon. These materials tend to be thin and flimsy. As a result, they are prone to ripping and don't offer adequate protectoin for footwear. Moisture will leak through resulting in wet or damaged clothing. And thin materials need something to hold them in place like draw strings or zippers, which can break with usage.

Shoe bags enclose the whole shoe. If you want to store items in your shoes just before you close your suitcase, the shoe opening is not accessible. In addition, shoe covers are square unlike your shoes, so they don't always fit right and are prone to snagging.
