Pros & Cons

Reasons to buy:

User Reviews

  • Toes are incredibly easy to step into.
  • Skis really well due to the forward pressure in the heel piece.
  • Risers are easy to flip.
  • Bought the Ion 10’s for my wife since I liked the 12’s so much.
  • Even though I know it’s not important, they look cool.
  • Much easier to step into than Dynafits.
  • The toe piece doesn’t ice up.
  • A good balance of weight and performance. Not the lightest and not the highest performing, but a good mix.

Expert Reviews

  • Best toe design on the market.
  • Easiest binding to step into.
  • Heel risers very easy to use.
  • De-icing the toe is simple – just open and close it a few times.
  • One of the easier transitioning bindings on the market.
  • Easiest tech binding to use in terms of icing, adjustment, and climbing risers.
  • The binding is well-made.

Reasons NOT to buy:

User Reviews

  • Incompatible with Dynafit crampons.
  • Customer service is extremely slow and unresponsive so hope that nothing goes wrong.
  • The brake can deploy during walk mode if it is iced.
  • Occasional pre-release.
  • The crampon mounts are inferior to Dynafit.

Expert Reviews

  • The brake can have icing issues.
  • The heel riser can flip back over unintentionally.
  • Very user-friendly.
  • Brake can occasionally deploy while skinning.
  • If you want to ski in-bounds a lot, go with the Marker Kingpin instead of these.


The G3 Ion 10 & 12 Binding is a mid-weight tech binding that has a robust and reliable feature set. It’s biggest strength is the ease with which the toe piece can be stepped into. The Ion strikes a very nice balance between weight and performance.
