Unopened, purchased recently from a direct-managed store. This is a thick footbed (insole). It has a four-layer construction and provides high shock absorption. It's a cup insole type that firmly holds the heel. If your shoes are too big and the fit is loose, you can make the fit tighter. As a guideline, you can expect a fit adjustment of about one size. For example, if you have a foot that fits perfectly in a US size 8.0, you can insert this footbed into a US size 9.0 shoe to achieve a nearly perfect fit. (This fit adjustment effect varies depending on the combination of the shoe's last and the shape of your foot, as well as individual differences in sensation. Please consider this as a guideline only.)
