Before buying boots, make sure you have measured and understand your feet. Many good boot fitters have scanners that will take a number of different measurements and allow you to select boots that are built for the type of feet you have. If you don t have a good boot fitter, find one. If that doesn t seem possible, then do the measurements yourself. And remember, shoe size doesn t make any difference when buying ski boots.
Most ski boots run in sizes based on European standards.
Measure the width across the ball of your foot by standing on a ruler, and then measure the length of your foot, heel to toe. Average width is about 40 percent of the overall length. Anything more than 40 percent of the length means you have wide feet and anything less means you have narrow feet. Next, measure your instep by wrapping a tape measure around your heel and over the instep. Average measurements here are about 120 percent of the length.
