What is the difference in size 7 and 7 and a half?

The difference between size 7 and size 7.5 in footwear typically refers to a half-size increase in length and sometimes width. This means that a size 7.5 shoe is generally about one-third of an inch longer than a size 7, which can affect the fit and comfort for individuals with varying foot dimensions. It's important to try on both sizes to determine which fits better, as sizing can vary between brands.
