KneeDropIt's your ground down boots
I don't think so, checked them recently and the toe/heel plates are still good.
shin-bangWing tightness is tricky To nail, toe height is important too. Like the dude above said. Probably your boots. If you don't want the bindings... I'll take them :D
I don't think it's the wings or toe height because they functioned perfectly for 3 years, just started acting up recently (and my boots are working perfectly with my other skis). I guess there's a chance that the toe/heel plates wearing down means the toe height and wings have to be re-adjusted, but the wobble is very severe (as in something like 1/2cm to 1cm of play), seemingly much more than having toe height or wings misadjusted would cause, especially since it came on pretty suddenly.
