Have NTN or ultralight AT boot with bellows? Need some support in your G3 Onyx bindings so your bellows don't flex down to the ski and maybe pre-release? Look no further as this is the fix you are looking for. If you own any of the Scarpa boots like the TX, TX Pro, F1 or F3 boots then this is what you need.

A required accessory when using the Onyx with Scarpa's F-series AT boots or other bellowed boots. Easy to install and remove. Does not hinder ski flex and works with G3 Onyx crampons.


  • Plastic with metal mounting reinforcements
  • Works with NTN & bellowed AT boots
