alpine ski boot - / ˈælpaɪn ˈski: buːt / -
noun
Ski boots designed to work with alpine bindings. They're made predominantly from plastic. They come in many different styles, sizes and flex patterns. They all share commonality with regard to the design of the heel and toe pieces as these must comply with the ISO 5355 standard. This outlines the interface between boot and binding, to ensure a safe fit.
\\ I'm thinking of trading these alpine boots for a proper FreeRide boot, what do you think?
