I listened to those who reviewed this item before I purchased: I originally wear a size 7 or size 7W, but I decided to order a size 7 1/2 W instead, and they work perfectly!  So far, they are so comfortable and stylish.  They are perfect for the airport and travel because you can easily slip these on and off.  They are also perfect for going out on the town, taking public transportation, going shopping, or visiting homes and/or places that require you to remove your shoes.  These work well with jeans, shorts, socks or no socks, toe-only socks, semi-casual dress slacks, and other garb.  I'd definitely recommend!
