Ski Boot Size Chart

On Nordica's chart a US men's 10 is a mondopoint 28 in the standard-fit column and 27 in the performance-fit column, and a US women's 10 is a 27 and a 26. Other brands' charts can differ. Treat any of those as a starting point rather than an answer, because the boot is built around your foot length in millimeters, not your shoe size. Measure both feet against a wall and bring the longer number to a fitting. A foot that measures 27.6 cm is a 276 mm measurement, not automatically a 28.

Close, but not identical. Mondopoint is the length of your bare foot in centimeters, measured from the back of the heel to the end of the longest toe under the ISO 9407 standard. Shoe sizes marked in centimeters usually include some extra room inside the shoe. A ski boot shell is sized to the foot itself, which is why a 26.5 boot feels far shorter than a 26.5 cm sneaker. Measure the foot, not the shoe.

They are fitted closer than street shoes. Nordica's own chart prints two mondopoint recommendations for every shoe size, standard fit and performance fit, one full size apart, and describes performance fit as its recommendation for skiers who ski regularly at higher speeds. Which of the two is right for you is a fitting decision made with your foot in the shell, not something to settle from a chart.

Snug everywhere, with your toes brushing the front when you stand tall and pulling back off it when you flex forward, your heel held down, and no pressure into the sides of the shell. The check a fitter does is the shell fit: liner out, foot forward, and the space behind the heel measured, roughly 15 to 20 millimeters in published guidance. Our fit guide takes toes, heel, forefoot, instep and calf one at a time.

In most lines two mondopoint sizes share one shell and the difference sits in the liner and footbed, which is why catalogs, ours included, list 22.5, 23.5, 24.5 and up. Whether a given brand builds a line that way varies by model, and it is one of the things a fitter checks with your foot in the bare shell.

The same system and the same numbers. The kids chart on this page runs from a mondopoint 14 to a 28, and our junior catalog starts at 17.5. Do not size up to buy an extra season, because a foot that slides inside the shell cannot steer it. Buy the length that fits now. If a child outgrows their boots within two years of buying them, bring the boots back for a 50 percent credit toward the next pair. Children who buy Surefoot orthotics with their boots get a new pair of orthotics free with their next boots if they outgrow them.

Mondopoint is a measurement, so a 26.5 is a 26.5 in every brand. The shoe-size columns are each brand's own conversion, and they do not all agree, especially on EU sizes. That is why this page prints one manufacturer's chart, labelled and dated, rather than a blended table, and why the guide leads with measuring your foot.

You can, and it will get you to the right rows of the chart. A tape measure gives you one number, which is length. A scan gives your fitter length, width and arch in millimeters for both feet, which is what actually decides between two shells that are both the right length. Measure at home to know roughly where you sit, then get the shell chosen on your foot in a store.
