On the S916's there is a small plastic piece that goes in each wing of the toe piece that keeps the metal biding from rubbing on the plastic of your boot and digging grooves. These plastic pieces (idk if there is a technical name for them) tend to pop out a fair amount and I need to get my hands on some to put in my bindings now and as spares for the future. Does anyone happen to have some of these they could sell me or know where I could get them? Any help is appreciated seeing as I can't find any info on them anywhere.
