TS ISO 5355

TS ISO 5355 is a standard for alpine ski boots that focuses on safe and compatible interaction with alpine ski binding systems. Its technical concern is the geometry and design of the toe and heel interfaces, which must work properly with bindings that have a release function. In other words, the standard is about the boot-to-binding relationship and the safety consequences of that interface, not about ski boot performance in isolation.

Why the boot interface matters for release performance

In alpine skiing, the boot is the key intermediary between the skier and the binding. The toe and heel areas use specific interface dimensions and shapes so the binding can retain the boot during normal skiing and release it in a controlled way when needed. In general technical terms, the design must balance retention and release: if the interface is incorrect, the binding may release too early, not release as intended, or fail to engage consistently. TS ISO 5355 covers the safety requirements, test methods, and marking related to that compatibility.

What this standard covers

• Safety requirements for alpine ski boots
• Toe and heel interface dimensions and design as they relate to compatibility
• Use with alpine ski binding systems having a proper release function
• Test methods
• Marking requirements

This listing is the Turkish adaptation of ISO 5355:1997 and is withdrawn in the TSE catalogue. Even so, it remains a useful technical reference for understanding how precise boot-to-binding interface design supports safe function in alpine ski equipment.
