Sealed sacks are engineered to circulate the OMGFit© compound, replenishing support continuously while you ski; this begins when you push your heel down, forcing the compound into channels that funnel it into the heel huggers.

Zip Fit built in OneMinuteFit self-molding system - the World Cup is fitted over the liner and onto the foot, then both liner and foot are inserted into the shell, and finally buckles adjusted and then everything is ready for skiing. The molding pack can be heating and softened many times over. OMFit© molding compound disperses into void to create complete uniform support and then firms up as the temperature stabilizes.

Designed for the use with the lowest volume, plug, race boots on the market

Spoiler forward lean is upright so that it can be adapted by the shell and shell cuff. The reinforced spoiler is independent of variables in the shell spoiler designs, while adding considerable support that reduces the need for tight buckle closures.

SPOTFIT personalization means that additional OMFit© compound can be injected at any time, precisely where you need it in the tongue or the liner, by any certified ZipFit dealer.

Thermally Moldable Ankle Panels are very thin and when the shell is heated, for initial fitting and molding, the heat transfers through the ankle reinforcing panels to thermally shape and mold to the shell's internal plastic shape while bonding the adhesives to the outer lining material. When cooled these panels boost the overall inner boot support and functional essence to enhance you with more leverage over the shell plastics and sensitivity over the skis. Therefore you need less closure tightness and have more amplitude in support and flex adjustability, and hence comfort. With normal liners tight buckling compresses the foam padding and constricts the feet, most often painfully.

The new Pro-Lacing and elastic tongue retainer system is very effective for wrapping the whole inner around the foot for the initial heat molding process. After molding the laces are optional. The laces are most effective in creating additional and independent "soft-brace" for foot, ankle and lower leg-shaft support within the stiff shells plastics.

Reinforced and asymmetrical tongue-shell

The elastic neoprene outer toe box wraps 180° around the whole forefoot for optimum sock-like comfort and adaptability to the shell.
