I just received these shoes and the sizing is more off than any other Michael Antonio shoe I've bought. I'm usually a size 8 but I bought a 7.5, according to the size chart, because reviews did not mention the sizing being too off. Well, with these shoes I will need a size 7, 6.5, maybe even 6. A whole 1 to 1 1/2 size difference is way too big of a deal, especially if you're not well informed. They will be returned, though beautiful & comfortable. I'm not sure about rebuying, hoping to get the right size. Either way, size 7 is sold out and they don't carry a 6.5. (-_-)   According to Michael Antonio size chart, the size 7.5 fits a foot, from heel to toe, that's 9.5 inches long. As you can see in the photos, the size 7.5 was NOT 9.5 inches in length, but 10 inches. I would recommend measuring your foot, minus half an inch, then buy the size that matches those measurements.
