Innovative aspects of this work included not only the stance geometry system ski boot but also the setup of a virtual design environment that was validated by experimental evidence.
Ski boot lateral stiffness.
Usually through trial and error but with some guiding parameters.
When looking at ski boots you ll see a flex rating described as a number usually somewhere between 60 and 140.
Head s nexo lyt 130 rs is a performance driven boot that s stiff and responsive but incredibly lightweight thanks to the use of graphene material which according to head is 300 times stronger than steel but only as thick as a single atom.
Boot flex ranges from very soft to race stiffness indicated by a numeric flex index that s usually a number from 50 soft to 130 very stiff.
Flex in ski boots refers to how difficult it is to flex the boot forward.
Stiffness in the realm of ski boots is also commonly referred to as flex and each boot has its own flex rating.
A ski boot s flex rating describes how much flexibility exists in the boot at the ankle area.
Boots with a stiffer flex are designed to deliver maximum speed and responsiveness.
Often this number is written on the outside of the boot cuff.
