This is a shoe keeper for MIZUNO WAVE BLADE shoes. It's from over a decade ago, when I was a student. Since it's old, the product condition is listed as "poor overall," but I think it's relatively clean. There are no noticeable stains, but there are minor scratches from use. The size adjustment parts are also in good working order. Both the screws on the back of the left and right sides have rust. Please check the photos for the condition. Please consider purchasing if you understand that this is a used item. Please refrain from purchasing if you are sensitive to such things.
