I am thinking of selling my old skis and wondering how adjustable the bindings are for different boots, so l can advise prospective buyers if the skis will work. The bindings are not demo bindings (Salomon 850) and are mounted the normal way, by drilling.My current boots are 313mm in length (from heel to toe) and l was wondering if the bindings will only work with boots that are within a millimeter of the ones they were mounted for, or if there is about a centimeter or so of adjustment possible.

If you had the bindings mounted yourself, with your boots, the installer should have set the bindings at a middle setting. You should be able to adjust the bindings about an inch forward or backwards. You could check, there is a tab at the back of the binding that you can lift with a regular screw driver.lift and slide the rear binding.
