Misaligned boot cuffs can force the leg into a "bow-legged" position, preventing the tibia from properly engaging the ski edge and leading to instability. Equipment Factors:
Chatter is rarely caused by just one thing; it is typically a combination of technical errors and gear limitations.
Wider skis (often 100mm+ underfoot) are designed for soft snow; when used on hardpack or ice, they provide less torsional stability and are prone to chattering.
Using an edge angle that is too steep for the slope's pitch can cause the ski to skip rather than slice through the snow.
