I totally understand that others are not happy with the size of these sleeves.  It really should be highlighted in the product description that each sleeve fits one pair of womens heeled shoes or one sneaker/tennis type shoe (as stated on the tag that comes with the product), meaning that 2 sleeves are needed for larger shoes and 1 sleeve for a pair of sandals or smaller shoes.  That said, these sleeves work very well for me.  I wear a womens size 9 shoe.  I can fit a pair of sandals or high heels in one sleeve.  For my larger Dansko shoes, I need 2 sleeves for the pair.  I still find that these sleeves are good to keep soil, etc. from my other clothing in my suitcase.
