An [[Ski touring|alpine touring]] (or randonee) binding allows the skier to have the heel of the ski boot free and the toe of the ski boot in the binding when using Nordic skiing techniques for ski touring, and to have both the heel and the toe of the ski boot in the binding when using [[alpine skiing]] techniques to descend the mountain.<ref>{{cite web |title=Ski Bindings - Components and Functions |url=http://www.abc-of-skiing.com/whatareskibindings.asp |archive-url=https://web.archive.org/web/20030620175316/http://www.abc-of-skiing.com/whatareskibindings.asp |url-status=usurped |archive-date=June 20, 2003 |access-date=13 October 2014 |website=ABC of skiing}}</ref> Most touring bindings are designed for ski boots falling under one of two ISO specifications:  
*ISO 5355:2019, for traditional [[Ski boots#Alpine|alpine boots]]. In this variation the pivot is located in the front of the binding.<ref>{{Cite web|last=Technical Committee|first=ISO/TC 83/SC 4 Snowsports equipment|date=April 2019|title=ISO 5355:2019: Alpine ski-boots — Requirements and test methods|url=https://www.iso.org/cms/render/live/en/sites/isoorg/contents/data/standard/07/48/74870.html|access-date=2020-12-09|website=ISO|language=en}}</ref>
*ISO 9523:2015, for boots in which the pivot is formed at the boot / binding interface.<ref>{{Cite web|last=Technical Committee|first=ISO/TC 83/SC 4 Snowsports equipment|date=August 2015|title=ISO 9523:2015 Touring ski-boots for adults — Interface with touring ski-bindings — Requirements and test methods|url=https://www.iso.org/cms/render/live/en/sites/isoorg/contents/data/standard/06/30/63099.html|access-date=2020-12-09|website=ISO|language=en}}</ref>
The two setups are typically incompatible in that the principle by which they affix the boot to the ski is different. "Tech" bindings engage the ski boot with pins, which hold the toe down and engage with the heel in downhill mode. Approximately 50% of ski boots have the necessary inserts. "Frame" bindings function similarly to regular alpine bindings, gripping a welt in the heel of the boot in downhill mode.<ref name=":4">{{Cite web |last=Bible |first=Aaron |date=2020-12-19 |title=The Best Backcountry Ski Bindings of 2022 |url=https://gearjunkie.com/winter/best-backcountry-ski-bindings |access-date=2022-03-16 |website=GearJunkie |language=en-US}}</ref>
