Recommendations

For optimal performance, pair these boots with gaiters for snow or scree. Break them in gradually on shorter hikes before tackling long alpine routes. The semi-automatic crampon compatibility allows use with strap-on or clip-on crampons for glacier travel. Regular cleaning and application of a waterproofing treatment will extend the life of the upper.
