Designed to prevent the toe strap on the Union Force bindings from adjusting itself. Reduced a bit of the range of rotation on the strap, but shouldn't prevent you from strapping in at the angle you want. I printed mine in PETG but maybe ASA is more ideal since it'll be in snow. Only tested with the Union Force 2023 bindings, please drop a comment if you try it on other models.

To Install:

• Take bindings off board
• Slide the insert from the bottom up into the slot you want to block off
