There are no standards for ski boot flexibility. Ski brands have long tried to create a set of industry standards, to no avail. Flex ratings usually range from 70 to 130 (beginner to advanced) and vary by manufacturer; meaning one brand’s 130 can be another brand’s 110. Even within a brand’s own product range, a 130 in one model can differ dramatically from a 130 in another. From our own testing, we’ve found equal flex ratings can vary by as much as 40 per cent. IS IT FOR ME? Do you have compromised stiffness for walk mode? Do you have compromised stiffness for lightweight boot? Do you have compromised stiffness for ease of entry? Are you a growing/improving junior racer? Are you a coach in hybrid boots for the grip and walk mode but want to drive a stiffer race-category ski? Are you a coach not sure if a boot is stiff enough for his developing racers? Are you an instructor with soft teaching boots still wants to perform? Are warm spring/summer temperatures softening your boots? Did you buy demanding new skis your boots can’t drive? Are you just looking for a stiffer boot?
