Your ski boots are the connection between your body and your skis. Your adventures in the snow succeed or fail depending on the right pair of ski boots. The fit and flex, in particular, will determine your choice. Boots that are too big do not convey your steering movements well. Boots that are too small are painful and give you cold feet. Flex indicates stiffness: the higher the value, the stiffer the boot and the more force you need to flex the boot forward. Experienced competitive skiers like stiffer boots, while freeride skiers go for more flexible boots. A good fit is the code word!
