Overview
ISO 22264:2006 defines the interface between adult Telemark ski‑boots (flexible sole) and Telemark ski‑bindings with toe and heel attachments. The standard specifies the required dimensions, design characteristics, test methods and marking so that boots and bindings interact reliably. It applies to Telemark boots sized 15.0 mondopoint and larger (size intervals 0.5 cm) and references ISO 9407 (mondopoint sizing) and ISO 554 (standard test atmosphere).
Key topics and technical requirements
- Interface dimensions: Prescribed shapes and tolerances for toe and heel contact areas (e.g., maximum front sole height ≈ 19.5 mm; rear sole height target 32 ± 2 mm). Dimensions must fall within stated tolerances; some limited deviations allowed if safety and function are not affected.
- Design features:
- Sole length difference between pair: ≤ 2 mm.
- Heel interface symmetry about the median plane within 1 mm.
- Defined “3‑pin” line and minimum straight part at the sole bottom for 3‑pin bindings.
- Side walls at toe: perpendicular to bearing surface within 0.5 mm tolerance over a specified area.
- Heel lateral walls: perpendicular or tapered 0–10° over at least 70 mm.
- Free space and clearances: Specified cones/arcs around toe and heel to ensure swivel range and handling clearance (front arc radius ~41.5 ± 3.5 mm; rear arc radius ~37 ± 4 mm). Templates/test bodies are used to verify these clearances.
- Test methods: Practical checks using templates, test bodies and measuring planes to confirm 3‑pin alignment, sole thickness and free spaces under standard atmosphere (ISO 554 conditions).
- Mounting point marking: A visible permanent line on each side of the lower boot surface (minimum 10 mm long, within 5 mm of the boot midline) indicates ski binding mounting position.
- Marking: Boots conforming to the standard must be marked with the reference “ISO 22264:2006” and the manufacturer’s name or trademark.
Applications and who uses this standard
- Telemark ski‑boot manufacturers and tooling designers - for designing soles that reliably interface with current telemark bindings.
- Ski‑binding manufacturers and system integrators - to ensure compatibility with boot interfaces and safe function.
- Test laboratories and certification bodies - to perform the standardized dimensional and clearance checks.
- Retailers, importers and procurement teams - to verify product marking and conformity.
- Ski safety engineers and standards committees - for interoperability and risk‑mitigation in equipment design.
Note: Some modern telemark binding systems function irrespective of sole shape; in such cases full compliance may not be necessary for equivalent safety, but ISO 22264 remains the key reference for traditional toe/heel attachment systems.
