Traditionally, ski sizing has been based on height, with exceptions made for weights that don’t fall within the norm. Metron has redefined these parameters and shifted the basis for ski selection from length to surface area in contact with the terrain. As Metrons are wider, you can have the same surface area on a Metron as on a much longer traditionally shaped ski.
To find the best Metron size for you, consider these factors:
To find your Metron ski size add together your weight index number, your skiing ability index number, and your preferred swing radius index number.
