Skiing straight down the fall-line with the skis parallel. From the German word meaning to shoot.

Self-arrest skills
Slowing oneself when descending by the use of poles as braking devices, or using some other available device such as an ice axe.

Sequential leg movement
Moving the legs one at a time in sequence, as opposed to moving them together, or simultaneously.

Set tracks
Machine-prepared tracks suitable for cross-country skiing, sometimes referred to as loipe. Not to be confused with trails, which are merely defined paths that may be skiied along.

Short-range waxes
Grip waxes with specific temperature ranges, used primarily by racers for maximum performance.

Tight-radius parallel turning, used mostly in narrow gulleys, or steep slopes.

From the widest point of the front section of the ski, known as the shoulder, to the ski tip.

Side camber

The amount of 'waisting' in a ski, determined by the difference between the widest (at both ends of the ski) and the narrowest (in the mid-section) points of a ski. See also waist.

Allowing the skis to slip sideways downhill, either directly down the fall-line, or at an angle to the fall-line.

Stepping (with skis parallel) either on the flat, or up or down a hill.

Siitonen step
See half skating.

Simultaneous leg movement
Moving the legs together at the same time, as opposed to moving them one after the other, or sequentially.

Single camber
A ski with an even flex from tip to tail, and can be either soft or hard.

Single dance
The Scandinavian's preferred term for a variation of two-skating.

Skate turning
A flat terrain or downhill turn, executed by one or more skating steps towards the new direction. It is considered an accelerating turn, unlike step turning.

A collection of divergent ski techniques where the skier pushes each ski to the side and not directly backwards.

Skating Wax
A more durable glide wax applied to the running surface of skating skis.

Ski Boot Footbeds
Ski boot footbeds are inserts (orthotics) molded to bring the load bearing parts of the foot in sync with the gravitational force of the skeletal system. A ski boot footbed is molded from a semi-rigid material which distributes the forces developed on the foot during a ski turn.

Ski flying
A form of ski jumping where the distance from take-off to the norm point is greater than 90 metres.

Ski jumping
A Nordic discipline in which jumps are made from a specially-constructed jumping hill. Points are awarded for distance and style.

Ski mountaineering
Mountain-climbing in winter, using Alpine skis (with special Alpine ski bindings which allow a type of walking movement) where possible.

Ski touring
In Europe this term refers to Ski Mountaineering, but in most English-speaking countries this term refers to backcountry skiing - the use of Nordic skis for touring away from resorts and set tracks.

Skiathlom Skiathlon
A competitive event with a ski race, ski jumping, and a slalom all in one race, and using only one set of equipment.

The process of allowing (or forcing) a ski to travel sideways over the snow in relation to the direction of travel, as opposed to carvinga ski.

These days they are a nylon substitute for seal mohair, and are a strip of material either strapped or glued to ski bases to provide phenomenal grip for climbing.

Invented by Arnold Lunn from the Norwegian word 'slalom', and to describe the method of descending by running through a series of gates (around poles or markers) set into the snow.

A forward or backward movement of the skis, with no skidding.

Slope edge
The point at which a slope noticeably changes angle from either steep to gentle, or vice versa.

Snow Plow
The snow plow is one of the first techniques a beginner skier learns. The front tips of the skis are almost touching, which slows the skier and helps maintain control.

Snow Skating
The term often used to distinguish skating on Nordic skis from that of ice skating.

Snowplough braking
Performing a snowplough glide with the inside edges of the skis biting into the snow to produce a braking force, and thus control speed.

Snowplough glide
Placing the skis in a convergent position, and flat on the snow, whilst descending a packed powder slope.

Snowplough turning
A snowplough glidewith weight-transfer onto one ski and then the other, to produce a series of controlled and stable turns. Known as wedge turning in USA.

Speed Skiing
Speed skiing is the art of going downhill through a straight measured course with the object of attaining the highest speed possible.

Something of little interest to the better skier

Star turning
Also known as clock turning, this is a linked series of step turns (either convergent or divergent) on the flat to change direction, lifting the tips or the tails, or the whole ski.

Steep-slope skiing
Often referred to as survival skiing, using turning techniques that ensure a safe arrival at the bottom of the slope, but should also be extended to include techniques for climbing such slopes.

A rotation of the legs or body to produce a turning force on the skis.

A skidding or sometimes stepping of the ski out into a convergent position, resulting in a situation where the stemmed ski is on its inside edge.

Stem turning
Downhill turning in which the uphill, or outside ski is angled out (either by lifting or skidding), pointing more towards the new direction, at the start of the turn.

Step turning
A linked series of steps, by lifting one ski from a parallel position (relative to the other ski) to either a divergent or convergent position, and then bringing the remaining ski back to the parallel position.

Step Parallel turning
Parallel turningwith one ski being lifted out to a new parallel position, allowing a greater turning force to be applied to the skis. Often used when skiing through slalom gates, or on difficult snow.

Step Telemark turning
Telemark turning with one ski being lifted out into a telemark position, thus allowing a greater turning force to be applied to the skis. Also used in the same manner as step-parallels.

A weight-transfer from one ski to the other, and lifting (stepping) one ski into a new position before transferring weight again, as opposed to skidding.

Stepping against the uphill ski
A weight-transfer from the downhill to the uphill ski, which is on its downhill edge.

Straight running
Descending directly down the fall-linewith skis parallel.

A movement of sliding one ski forwards and applying pressure onto it by a weight shift, followed by a resultant glide.

Stride double-poling
A stride onto one foot, followed by a double pole action. In its simpler form, this is repeated onto the same foot each time, but to balance the work performed by the legs, alternate foot striding is used by advanced skiers.

Stride length
The distance travelled between one stride and the next (not the distance between each foot in a given stride).
