ISO 9523:2023

This document specifies the dimensions and characteristics of the interface, requirements, test methods and marking of ski-boots with a rigid ski boot sole that are used with current systems of touring ski-bindings with attachment at the boot toe and boot heel, the proper release function of which depends on the dimensions and design of the interfaces.
This document is not necessarily applicable to touring ski boots that function independent of the sole shape with certain ski-binding systems.
This document is applicable to ski-boots of sizes 15,0 and larger in the Mondopoint system (see Annex A).
It is applicable to rigid touring boots. Boots with softer shells such as Telemark boots are excluded as they do not have the necessary shell stability to act as part of the release systems.
