They are not demo bindings are were mounted for a size 10 and can go down a few sizes and up a few sizes. My current boot size is 305mm which is roughly a size 9 or 8.5. So if your foot is smaller than an 8.5 or larger than an 11.5 I would say all you need to do is have the bindings remounted to accommodate a different size... But as you can see there is some wiggle room if you are within the range. The item "16-17 Volkl Kendo Used Men's Skis with Marker Griffon Bindings 170cm" is in sale since Sunday, May 2, 2021.
