Ask just about any professional skier about their most important piece of gear and you'll hear about their ski boots. Lindsey Vonn is no exception, and she clearly has a lot to say about boot science. While the degree of attention that goes into her boots is likely overkill for most of us, it's still interesting to get a glimpse at what is, in essence, the most complicated shoe-fitting in the world.
If it's not apparent from the video, bootfitting is a complex and delicate science essential for ski racers' success. However, not just top-level athletes can benefit from well-fitted boots. Even a novice skier will learn faster and have a more enjoyable time in boots which don't feel like medieval torture devices. Simply getting a custom footbed or a molded liner can make a world of difference.
