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.

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.)

Description & Features

The Redster STI 90 LC is for lighter junior racers, but the only thing junior about this race boot is the cuff height, just a little bit lower for less-developed legs. World Cup Liner makes sure it’s got great foot feel, and the Slim Race Shell makes it easier to flex than regular junior race boots. Power Control lets racers adjust both the forward lean and the precise stiffness of the boot – allowing them to lock in the feel for tons of confidence on race day. Let junior racers feel like they’re in the big leagues with the Redster STI.
