Patent ID: 8776612

Claim:
A method for determining the dynamic characteristics of a ski boot comprising an upper shell and a lower shell, comprising: a) defining at least a first, second and third parameter, (S), (P) (R) which represent dynamic characteristics of a ski boot; b) experimentally determining the value of said first parameter for said ski boot; c) experimentally determining the value of said second parameter for said ski boot; d) experimentally determining the value of said third parameter for said ski boot; e) defining a dynamic behaviour of said ski boot based on a combination of the values measured in said steps b) to d), wherein: said first parameter (S) is a bending moment, measured in Nm/°, to be applied to bend an upper shell of the ski boot to a first angle α relative to said lower shell starting from a neutral position; said second parameter (P) adimensionally expresses a stiffness increase during the bending from a neutral position to a maximum bending position of the upper shell relative to a lower shell; and said third parameter (R) expresses a speed to which the upper shell returns to the neutral position from a maximum bending position relative to the lower shell.
