Standard Terminology Relating to
Snowboarding
This standard is issued under the fixed designation F 1107; the number immediately following the designation indicates the year of

1. Scope
1.1 This terminology covers terms used to describe the
geometry and common hardware used on snowboard skis,
snowboard bindings, and snowboard boots.

for regular-foot (left foot forward) and goofy-foot (right foot
forward) snowboard binding mounting positions (Fig. 5).

discretion, may be used to indicate nominal snowboard ski length or
snowboard ski size when rounded to common increment.
