Alpine ski boots with improved walking soles - Interface with alpine ski-bindings - Requirements and test methods (ISO 23223:2024)


This document specifies the requirements, test methods and marking of ski-boots which are used with current systems of alpine 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. Alpine ski boots with improved walking soles are intended to a better walkability without affecting the function of the alpine ski binding designed for improved walking soles. For ski-binding systems that function irrespective of the sole shape or that have different requirements for the sole dimensions, it is not always necessary for the ski-boot soles to comply with this International Standard in order to achieve the desired degree of safety. It applies to ski-boots of sizes 15,0 and larger (Types A (Adults) and C (Children)) in the Mondo point system (see Annex A).
