Tips

For optimal performance, pair these boots with a fully automatic crampon such as the Petzl Lynx or Grivel G14. Break them in on moderate hikes before committing to long alpine routes. Treat the leather and fabric with a suitable waterproofing agent periodically to maintain water repellency. Store in a cool, dry place away from direct sunlight to extend the life of the GORE-TEX membrane.
