RundleBlobsso far, contradictory information....who do I trust?
it's the piece that goes under your boot and lets it slide out if you fall. some of the afd's are adjustable and some are fixed but all in all you should have one under your boot. go to your local shop and ask their help on the issue.
A shop is going to charge you way too much for that little piece of plastic. If your boot isnt the right height for the binding, attach something there to fix it yourself. You dont need to scrap the whole binding because of that.
AFDs are present for a reason. The antifriction device will provide the correct upward pressure in order to keep your boot toe within the wings of the binding, as well as provide a surface for the boot sole to slide before and during a release. Without it, your boot will move both up and down and side to side. It will affect the skiing experience and make the binding less safe overall. Yes you can ski without it but it is a question of whether you should or not, and the answer is no, unless you don’t care about being safe
