The holes on the side greatly improve the skiers ability to flex their
uphill boot allowing them to apply greater edge pressure on the up-hill
skis. The world cup racers tested this feature on the boots for the
past few seasons. Before it was released to the public they skied with
that section of the boot covered in Duct tape.
Salomon boots tend to fit a wide variety of feet so I am not surprised
that you're pleased with the fit.
