Triple Injected Frame – A high performance, multi-density shell optimizes easy entry, foot wrapping, comfort and energy transmission.

Easy Entry Shell Design – Four channels are cut into the throat of the boot to reduce the thickness of the material, providing smoother entry and better wrapping of the foot.

Rear Support Tuning

Flex Stance Tuning – By adding screws to the spine of the cuff, the link between shell and cuff becomes stronger and the flex of the boot stiffer. Additional screws also increase the forward lean of the boot for a more aggressive stance.

Double Canting – Two different levels of canting adjust to properly align the body and boot.

4 Micro-adjustable Spineflex Racing Alloy Buckles – A revolutionary buckle concept, the Spineflex is built with a flexible element and a constant closure point. The flexible element allows the buckle to adapt to the shape of your shin, while the constant closure point increases the overlap between shell flaps, reducing pressure points.

1 Supermacro Ratchet – An adjustable, ratcheted toothplate provides 28 mm of calf adjustment.

2 Double Power Levers – Developed and patented by HEAD, the double power lever reduces the effort needed to close the buckle by 50%.

40 mm Double Power Booster Hook-and-Loop Fastener Strap – This strap works as a double pulley for better closure and a tighter fit. The elastic Booster strap allows for a more dynamic response, resulting in more precise transmission and faster ski reaction.
