Alpine (DIN)
The required standard for use in alpine bindings. Known interchangeably as DIN, TUV or ISO 5355, this standard is synonymous with dependable release and bomber security. (Though our lawyers tell us that no boot/binding system can guarantee your safety in all circumstances.)

Alpine Touring (AT)
Sometimes referred to as UNI or ISO 9523, the universal norm for alpine touring features a lug sole for maximum traction over any terrain. These boots are only recommended for use in touring bindings. Or walking anywhere requiring positive traction.

Tour Lite Tech (TLT)
Also known as the Dynafit® System or Tech, TLT represents the lightest alpine touring bindings available and requires special boot fittings. SCARPA has 10 boots with TLT fittings, including the Terminator X and Terminator X Pro telemark boots (NTN) that are compatible with touring bindings. SCARPA is the only licensed manufacturer using Dynafit®-made inserts, both standard and “Quick Step-In.”

75mm Telemark Norm (75mm)
As the name implies, the traditional “duck-billed” boot is the telemark norm. This has been the standard for telemark boots and bindings since the telemark revival of the 1970s.

New Telemark Norm (NTN)
The revolutionary New Telemark Norm boot standard fits Rottefella’s NTN bindings and features an AT spec toe. With an underfoot attachment, this boot/binding system redefines telemark performance.
