Yes, Alegria sizing can be confusing. I wear both a 38 and a 39 standard width depending on the style. I can also wear a 38 wide width in certain styles. Difficult to order online for sure! I have one foot that's really an 8 wide due to a bunion, and one foot that's really an 8.5 medium. Usually a 38 fits if it's an open toe/open heel sandal like the Fiona, which was the last TSV. In a closed toe sandal or a closed toe & heel style, I'm usually a 39, especially if I sometimes wear a sock. Check out the Alegria sizing info and chart on the Alegria shoe shop site. You'll see that Alegria shoes come in either their Classic sizing OR their New sizing, and there is a difference. You need to check the sizing for the particular style you want. For example, the style I recently ordered comes in the Classic sizing -- a size 38 is 7.5-8 and a 39 is 8.5. That's how I knew to order the 39. IF the style was in New sizing, it would be size 38 is 8-8.5 and 39 is 9-9.5. Big difference. So check the authentic Alegria charts before ordering from QVC, since Q charges for returns.
