Dynafit made the Men's TLT8 Expedition CR boots for committing ski mountaineering routes that demand high-performance equipment. Constructed with a carbon-infused Lambda frame and Grilamid shell, these boots provide exceptional lateral and forward rigidity for improved strength and power transmission on the descent while enhancing walkability and ease of entry. Constructed with a Speed Nose, the TLT8 Expedition boots feature a short, smooth toebox with a more rearward toe fitting placement for optimum touring efficiency and minimum resistance, so you can save your energy for the descent. Our favorite feature is the Ultralock 4. 0 upper buckle that's connected via a cable to the adjustable lower, letting us tighten and loosen the entire boot in one motion.
