One & Co. alos looked for ways to eliminate mass from the outsole, to keep the boot as light as possible. through research and trial and error, the team discovered that the lugs, which were of a heavy rubber, were needed only on the heel and toe of the places that touch the board. Traction on the shank area is less important than it would be on a hiking boot since snowboarders walk mostly on snow, not logs but arch support is still crucial, so injected plastic, which is both more structured and lighter than rubber, was used for arch support on the shank.
