context_page_description: Ski boots are footwear used in skiing to provide a way to attach the skier to skis using ski bindings. The ski/boot/binding combination is used to effectively transmit control inputs from the skier's legs to the snow.
context_section_description: Although randonnée is considered as an alpine sport, it basically combines the cross-country stride for uphill portions and then conventional alpine techniques on the downhill. The equipment uses most closely compares to modern telemark systems, with a stiff plastic boot offering good downhill control, and a binding system that allows it to pivot at the toe for cross-country striding. Different models trade off light weight against downhill performance. They have a rockered, rubber sole to allow for easier walking. This means that they will not fit in ordinary alpine bindings. Instead, the interface between alpine touring boots and bindings is defined by ISO 9523. Other attachment methods exist and prominent amongst these are the Tech bindings and fittings that were first commercialized by Dynafit as the TLT. As yet, these are not covered by an international standard.
