Wider boots are more comfortable than narrow boots, especially for folks with wide feet. However, that’s true only up to a point. Boots that are significantly wider than your feet offer a sloppy fit and if your feet move around too much inside the boot, it allows for enough movement inside the boot that you can injure toes and foot more easily by slamming the foot inside the boot. Beginner boots are generally wider by default to accommodate new skiers who have a lower tolerance for foot compression in pursuit of performance.
