Selecting the correct ski boot is one of the most important equipment decisions a racer can make. A properly fitted race boot improves control, edge engagement, power transfer, and comfort while helping athletes develop strong technical skills. This guide explains how to determine both the correct boot flex and Mondopoint size for alpine ski racing.

Quick Navigation: Boot Flex | Boot Size | Fit Notes

Determining Ski Boot Flex

Ski boot flex refers to how much resistance a boot provides when the skier flexes forward. In general, heavier and more aggressive racers require stiffer boots, while lighter or less experienced athletes benefit from a softer flex that is easier to bend and control.

A useful starting point is to compare racer weight to the recommended flex range below. Most racers perform best when their body weight is approximately 10–30 pounds higher than the flex rating of the boot. Skill level, strength, terrain, discipline, and personal preference can all influence the ideal choice.

Race Place Tip: These recommendations are intended as general guidelines. Consult your coach, boot fitter, or Race Place ski expert for personalized recommendations. Ski boot flex ratings can vary significantly between manufacturers.

Ski Boot Flex Recommendations

Racer Weight (lbs) Racer Weight (kg) Recommended 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 Your Ski Boot Size

Ski boots use the Mondopoint (MP) sizing system, which measures foot length in centimeters. Unlike street shoe sizes, Mondopoint sizing provides a more precise measurement for ski boot fitting.

For the most accurate measurement, stand with your heel against a wall and measure from the wall to the tip of your longest toe in centimeters. The resulting measurement is your approximate Mondopoint size.

Because race boots are designed for maximum precision and responsiveness, many racers choose a close-performance fit. Actual fit can vary slightly between brands and models, so we recommend trying on a similar boot whenever possible.

Race Place Fit Notes

  • Junior racers often benefit more from a properly fitting boot than a stiffer boot.
  • A race boot should fit snugly without causing pain or restricting circulation.
  • Performance-oriented race fits typically feel tighter than recreational ski boots.
  • Boot flex ratings are not standardized and can vary between manufacturers.
  • Professional boot fitting can significantly improve comfort, performance, and long-term development.

Technical Info

97mm LAST

An exact, race-inspired 97mm last designed for skiers with low volume feet or skiers seeking more foot compression and control without sacrificing comfort.

DUAL 3D LINER PERFORMANCE

The inside of the liner perfectly wraps the foot and lower leg for the most comfortable anatomical fit while the outside is pre-formed to the shape of the boot to limit movement and thus ensure superior precision and power transfer. Offers out-of-the-box fit for all-day comfort and control.

80% Customizable thermo liner with medium density foam for a precise soft tension fit.

NATURAL STANCE

Canting and forward lean angles that put you in a more natural stance for enhanced edge release, balance, and steering.

DUAL CORE

By sandwiching a softer plastic core within more rigid plastic results in drastically enhanced elastic tension within the boot delivering power, snap and rebound. Softer plastic is targeted to areas that wrap the foot and lower leg, allowing easy, comfortable entry and exit. DUAL CORE provides a new level of ski boot performance as reactive and dynamic as your own body.

ARTICULATED RACE BUCKLES

The streamlined, asymmetrical buckle design guarantees maximum shell wrapping and easier lever handling. Low profile buckle sits as close to the boot shell as possible with articulating hinge for easier opening and closing.

SHORT CUFF

The shorter cuff design (15mm in the rear/20mm in the front) offers skiers with shorter leg shafts a more natural stance and range of motion with increased comfort.

RACE FLEX ADJUSTMENT

Introducing Race Flex Adjustment - the revolutionary feature in alpine ski racing boots that allows you to fine-tune the flex of your ski boots. By simply swapping the black carbon spine insert for the included blue polyurethane alternative, you can seamlessly dial down the boot flex by approximately 10%.
