Fit & Performance Technology

Junior Fit

The shell and liner are engineered for smaller feet and lower-volume calves, creating a more secure fit that improves comfort, balance, and ski control.

Mono Injection Shell

A mono-injected polyurethane shell delivers smooth, predictable flex and efficient energy transfer, helping junior racers build confidence with every turn.

Easy Step Insert

A softer insert over the instep allows the shell to open wider, making the boot easier for young skiers to put on and take off.

Polyurethane Shell & Polyolefin Cuff

The polyurethane shell provides durability, rebound, and precise power transmission, while the lightweight polyolefin cuff creates a progressive flex suited to developing racers.

Adjustable Flex

Rear cuff screws can be removed to fine-tune flex, allowing the boot to better match a skier's size, strength, and progression.

Micro-Adjustable Aluminum Buckles

Durable aluminum buckles provide secure closure and precise adjustment for a consistent fit throughout the race season.
