Slalom Edging Technique: How to Build Speed Through Every Turn

Skiing slalom fast is rarely about "pushing harder". The skiers who consistently find time in the gates often share one advantage: they use the initiation phase (INI) as an accelerator and keep the steering-out phase (STEOUT) short to avoid unnecessary braking. Edging technique is therefore not just about getting grip — it's about controlling how speed builds and how effectively you enter the next turn.

Why the INI Phase Defines Your Line

In slalom, it is not always optimal to minimize the phase where the ski slides flat between turns. Research shows that elite skiers often extend the INI phase to increase the center of mass forward speed before the next steering phase begins. For every second the INI phase is extended, the total time decreases by approximately 0.45 seconds, allowing you to ski faster without necessarily adding more aggressive edging.

The goal is not to move from transition to clean edge as quickly as possible. The goal is to create an efficient acceleration phase where the body continues to gain forward speed while the ski still has room to oscillate between edges. During this part of the turn, INI acts as a kind of "accelerator" for your movement.

An effective transition still starts in the lower legs. By leading with the lower leg and letting the torso follow, you create angle to the slope without throwing the upper body inward. This gives you the ability to achieve stable, controlled edge grip when you move into the more active part of the turn.

Balance and Pressure Distribution Through the Turn

Balance in slalom is dynamic, not static. At the entry of the turn, the center of mass is often slightly forward to help the ski enter the right path. As you build pressure through the apex, you can let the body center over the ski again without blocking the movement. At the exit, you reduce STEOUT so that you don't brake into the next turn.

The edge change — or turn switch — often happens flat during the transition between edges. It is not an abrupt "jump" between two edge positions, but part of the dynamic pendulum action where the skis slide with little side pressure. This flat phase is important because it allows you to transfer speed forward and prepare for the next steering phase in a controlled manner.

Many skiers lose speed by standing too upright or too far back as pressure increases. Think about letting the hips lead the movement and keeping the upper body stable relative to the slope — not relative to the horizon. This creates constant contact with the ski and reduces the risk of skidding, while also helping you keep STEOUT short.

"Edging is not about leaning in — it is about using movement efficiently. The fastest skiers do not just create strong edge grip; they build speed during INI and let the turn flow without unnecessary braking." — Marcus Lindqvist, FIS slalom coach

Common Mistakes and How to Correct Them

Most technical issues in slalom become obvious once you know what to look for. Here are some of the most common patterns we see among club skiers and masters:

| Common Mistake | Symptom | Correction | | --- | --- | --- | | Too short INI phase | Loses speed between turns | Practice longer glide phase with active forward center-of-mass movement | | Long STEOUT phase | Brakes into the next turn | Focus on faster edge change and early initiation of the next turn | | Inward lean with upper body | Loses outside edge, ski skids | Keep torso more upright, rotate with lower leg | | Stiff outside leg | Ski bounces, uneven pressure | Actively flex through the turn, avoid locking the knee | | Hasty transition | Short edge grip, jerky skiing | Count tempo: let the turn "breathe" before changing |

Work on one correction at a time. Film yourself from the side and compare entry, apex, and exit in each turn. Small adjustments in timing often provide greater time savings than simply increasing physical pressure.

From Understanding to Automated Movement

Edging technique only becomes truly valuable when it no longer requires active thinking. This requires repetition with intent — not just more turns, but turns where you know exactly what you're focusing on. Alternate technique sessions on gentle slopes with full speed in gated environments once the basic pattern is established, with particular focus on keeping INI active and STEOUT short.

Accelerate Learning with Video Feedback

Feeling the difference between good and bad edge grip in real time is difficult — the body often lies. With video feedback, you can see exactly when INI starts, how the center of mass moves, and when STEOUT becomes too long. By uploading a clip and getting AI analysis of your specific skiing, you can identify your patterns and get concrete focus points for your next session on snow. It's the fastest way to go from theory to measurable improvement in the gates.
