GripWalk, alpine and touring soles are compatibility categories. Read the sole marking and the binding’s exact model instructions; a boot that clicks into a binding is not proof of an approved combination.
Read the sole standard
| Marking | Category |
|---|---|
| ISO 5355 | Alpine ski-boot sole. |
| ISO 23223 | Walking-enhanced alpine sole used by current GripWalk guidance; A denotes adult and C child. |
| ISO 9523 | Touring ski-boot sole. Do not treat it as interchangeable with GripWalk. |
Match the binding, not a logo in isolation
A GripWalk-compatible binding is designed for the combinations its manufacturer lists. An older alpine-only binding may not accept a walking sole. Multi-norm labels also require reading the specific model’s compatibility chart; they are not permission to use every boot. Adult/child distinctions and touring/pin interfaces need their own checks.
- Photograph the boot’s sole markings and binding model name. If the sole has been replaced, identify the installed part.
- Have an authorized dealer confirm the permitted combination and inspect sole wear.
- Use the actual boot for model-specific adjustment and release testing. Replacing soles can change the setup.
At a rental counter
Tell the technician if bringing your own boots. Give them the boots before accepting skis, and ask them to confirm both compatibility and adjustment. Do not solve a mismatch by changing release indicators or assuming similar-looking soles are equivalent. Boot-sole length is a separate measurement used in setup.
