| Strength | Light & efficient climbing |
Tech bindings (pin bindings) are lightweight alpine touring bindings that hold the boot with metal pins clipping into dedicated inserts in the boot’s toe and heel, requiring tech-compatible boots. The pivoting toe makes climbing very efficient, and their low weight makes them the standard for serious ski touring and ski mountaineering, trading some downhill stability and easy release versus frame bindings.
Light and efficient
The light touring choice among ski bindings for ski touring; the heavier, boot-flexible alternative is frame bindings.
Frequently asked questions
What are tech bindings?
Tech (or pin) bindings are lightweight ski touring bindings that secure the boot using small metal pins at the toe and heel that lock into matching inserts built into tech-compatible boots. The toe pivots freely for an efficient climbing stride, and the heel locks down for the descent. They're far lighter than frame bindings.
Tech bindings vs frame bindings?
Tech bindings are much lighter and climb more efficiently (the toe pivots on pins with no heavy frame to lift), favored for serious touring and ski mountaineering; frame bindings are heavier but work with regular alpine boots and feel more like resort bindings on the descent. Tech wins on weight, frame on boot compatibility and familiarity.
Do tech bindings need special boots?
Yes — tech bindings require boots with 'tech' (pin) inserts in the toe and heel. Most modern touring boots have these, but standard alpine resort boots usually don't, so you can't use them with tech bindings. Frame bindings, by contrast, accept regular alpine boots, which is one of their advantages.
