Whether on narrow ridges or steep northern faces, speed mountaineers can confidently tackle even the most challenging terrain with the Blacklight. Its lightweight design and generous cuff rotation make the shoe an ideal companion for long tours. Instead of a traditional tongue construction, the Blacklight features an innovative Tech Gaiter that protects against cold and wind while ensuring a perfect fit. In descent mode, the patented Hoji-Lock system showcases its strengths: the cuff and shell form a completely interlocked unit with no play for optimal power transfer.
