Innovative footwear for the mountains is La Sportiva's speciality and they prove it yet again with the Sideral. This boot is race ready at 1063 grams and an incredible 60 degrees of cuff articulation. With a wider last than other lightweight boots the Sideral is sure to keep you warm when skiing big mountain lines or hot lapping your favorite powder stash. It will even take on the occasional ski mountaineering race. The cuff forms an exoskeleton around the back of the boot eliminating the need to replace and remove a tongue, while its own permanently attached touring tongue is equipped with a tele like bellows for the ultimate freedom of motion.
