The Grand Prix is identical to the World Cup, with 10 percent more OMFit cork composite.
The GRAND PRIX is designed for low volume feet in correctly sized medium- to low-volume shell models. (2,000 cc or 98 to 100-plus-mm shells), or for medium volume feet in shell models of 98mm or more.
Zipfit offers a number of different models offering comfort and great performance. You choose the model by volume according to your personal foot-leg morphology (volume and shape) and its anatomical compatibility with the shell's inner shape.
All Zipfit models share the same laces, power strap and elastic Neoprene and wool inner toe box. The combination of craftsmanship and technology is behind Zipfit’s legendary power-edging control and sensitivity of balance — two of the most important considerations for all skiers. They are all available with leather or Neoprene inner lining.
And remember, the SpotFit kit enables you or a boot tech to add or-extract precise doses of OMFit molding composite into or from your Zipfit inner boots, ensuring they fit your feet and shell perfectly.
