Determining Ideal Ski Boot Flex

The best method to determine the boot flex is by the athlete's weight. Adding 10-30 lbs to the boot flex results in the ideal weight range for that flex. This can vary based on an athlete's skill level and aggression. These are loose guidelines, and you should consult your local coach or ski expert for more specific recommendations.

Ski Boot Flex Chart

Racer Weight Pounds	Racer Weight Kilograms	Boot Flex
50-80	23-36	65
80-100	36-45	70
100-120	45-54	90
120-150	54-68	110
130-160	60-73	120
150+	68+	130-140

Determining Ski Boot Mondo Point (MP) Size:

Ski boots are sized with the mondo point system, which is a direct measurement of the foot in centimeters (cm). You may use the chart below to estimate your mondo point size, or measure the length of your foot in centimeters to determine your size. (Note: There tend to be slight variances between manufacturer's sizing and we recommend that you try on a similar brand or model before ordering to best determine the right size for you.)
