Binding Angle
Forward stance -
Suitable for most purposes, both feet are angled forward. Frequently the leading foot is angled roughly 15° to 21° and the trailing foot at 0° to 10°. A downside is that a rider's balance is notably different when riding in reverse compared to their forward stance.
Alpine stance -
Used primarily for alpine racing, the leading foot may be from 50° up to around 70° and the trailing foot generally identical or up to 10˚ less.
Duck stance -
Useful for tricks by removing the forward bias altogether, the feet are angled outwards in opposite directions. This stance is becoming increasingly popular, and is the most resilient of the three. The feet do not actually have to be angled equally outwards to be considered duck stance.
Flat stance -
Popular with riders who wish to have a consistent stance riding forward or backward, a flat stance is simply one in which both feet are perpendicular to the length of the board. This may result in "toe drag" on narrower boards or if the rider has larger feet, then the rider's toes overhang the edge of the board and make contact the snow when turning.
