Tech (pin) bindings require boots with tech fittings—metal inserts in the toe and heel that engage with the binding's pins. Frame AT bindings (like the Marker Duke PT or Salomon Guardian) grip the boot sole like an alpine binding and can work with any boot that has an alpine-compatible sole, including some AT boots with hybrid soles. Tech bindings are much lighter and more efficient for touring. Frame bindings are heavier but offer more familiar alpine-like release characteristics and work with a wider range of boots. Most dedicated AT skiers use tech bindings with tech-compatible AT boots.
