Stop struggling with your ski technique—the problem might be your bindings!

In this episode of First Chair, host George Thomas talks with biomechanics expert Lou Rosenfeld about the "Magic of 4 Millimeters." Many skiers spend months trying to fix their stance, but Lou reveals how moving your binding position just a fraction can instantly put you in a balanced, powerful position.

We debunk the "Engineer Myth"—the idea that the factory line on your skis is the only place your boots should go. Lou shares insights from his research with Atomic and Nordica to explain how manufacturers actually pick those marks (and why they might be wrong for you). Whether you're a pro instructor or a weekend warrior, learning how to adjust your mounting point can turn an "unforgiving" ski into your favorite piece of gear.

In this video, you’ll learn:

- Why the "ball of foot" method still matters in the age of shaped skis.

- How binding placement affects your performance in moguls vs. groomed runs.

- Why skiers with smaller feet (including many women) are often mounted too far back.

- The "12-minute fix" that can save you 12 weeks of frustration on the hill.
