Abstract: A method and apparatus is disclosed that allows a user to individually or simultaneously customize the pitch, roll, height, yaw, linear placement and lateral placement of his/her boots on his/her skis. This system allows the user to stand in a position while skiing that is closer to his/her natural position and to have the parameters of such a stance measured and quantified, thereby improving comfort, performance, and safety. As opposed to the limited variation in only some parameters described by current art, this invention allows significant variation in all individual parameters and simultaneous customization of all parameters. This simultaneity is important because of its increased ease to the skier and because altering any one parameter can change the center of pressure, thus creating the need for additional changes until the perfect combination of adjustments is made.
