|Comparing lightest ski mountaineering gear:|
This page compares 18 lightest ski mountaineering and rando racing bindings that are under 200g, and are currently available in stores. The 18 models could be grouped, therefore, creating only 11 distinctive ones – some use different combinations of the same parts (toe, heel, plates…) to create new models.
This bindings comparison page will be updated as new models are released and become available, or whenever you suggest a new boot in comments below or via email (please include a link). Also, should you find any mistakes please report them - comments below or via email (include your source’s link).

Bindings research with Jonathan Shefftz:
I (Stano) was happy to collaborate on creating this page with Jonathan Shefftz who is the most thorough equipment geek, tester and researcher I know. Jonathan organizes a three-event race series in New England (http://www.facebook.com/NERandoRaceSeries) and has won ten races at seven different venues. He is an avalanche safety instructor (http://avycourse.blogspot.com) for the National Ski Patrol and American Institute for Avalanche Research and Education, and is a member of the American Avalanche Association Governing Board.
We believe all weights are provided without screws, and without any parts that are removable (crampons…) .
» We are trying to confirm with ISMF what is legal and how this is determined.
Toe auto-lock info is not consistently communicated by manufacturers. Also, with the ISMF rules not being really clear of what a toe release means (no specs or DIN/ISO discussion) it does not mean that an auto-lock binding is outright illegal. (As long as the binding has a “toe unlocked” mode, we believe, you should be fine.)
We encourage you to study the ISMF rules for 2012-13 season, bindings are discussed on page 8 - http://www.skintrack.com/skimo-racing/2012-2013-ismf-competition-rules/
There is a “white list” for ISMF approved gear, however, it seems to list only gear from brands that are part of their manufacturers pool. For example, Pierre Gignoux doesn’t appear to be part of this pool, therefore, it is not clear whether his bindings are ISMF legal. The same applies to other brands (and with any other equipment, not just bindings).
Crampon attachments marked as “removable” are sometimes included in the price, and sometimes not. It’s not clear.
Also, all adjustment plates are sold separately, unless the plate is fully integrated with the binding. Check before buying.
It is possible to find light race bindings from Colibri, Montura Haereo or Merelli; however, we decided to omit them from this comparison as there is almost no official information available and they seem “impossible” to buy.
In alphabetical order by brand.
