Stiff boots for driving big skis. These alpine touring boots offer fantastic downhill performance thanks to a one-two punch of power and precision. La Sportiva used the best features of their Sparkle 2.0 Boot and gave it a stiffer feel. 125 Flex uses a simple, yet effective tongue with 2 layers that lock into one another in ski mode and move freely when in tour mode. The carbon reinforced Grilamid vertebra functions like an exoskeleton behind the cuff and adds even more stiffness for maximum power transfer.
