Rossignol designs the HERO WORLD CUP ZJ+ boots for elite alpine racers who demand immediate power transfer and uncompromising control. These unisex boots are designed for skiers competing at the highest level, from giant slalom to speed disciplines. Their Plug Shell with extra-thick walls and race hinge define an architecture focused on pure performance.

The HERO WORLD CUP ZJ+: a shell designed for power transmission

The polyether shell features a Plug Shell design with reinforced wall thickness, which reduces energy loss between the skier’s movement and the ski’s carving action. Dual Core technology relies on the simultaneous injection of two distinct plastic hardness grades: each zone of the shell responds to a different load, with targeted power transmission where force is applied and a crisp rebound for smooth transitions between turns. The polyether collar extends this design philosophy by keeping the ankle in a neutral, upright position, which facilitates direct engagement with the edge.

A flex rating of 120 and a last width of 92 mm for a balance between precision and support

With a flex rating of 120 and a last width of 92+ mm, the boot falls within the upper range of competition boots, without completely sacrificing comfort. The World Cup Race Fit+ liner is based on the 92 mm race last but features slightly roomier ankle and forefoot areas, allowing you to ski multiple runs without compromising precision. The ultra-thin, cork-laced liner conforms to the shape of the foot with minimal bulk, preserving the direct feel between the foot and the shell.

Precise adjustments for optimal positioning

The four micro-adjustable, screw-mounted aluminum buckles are designed to sit as close as possible to the shell, contributing to a streamlined aerodynamic profile. The 40-mm powerstrap provides support for the upper shin without causing excessive pressure points. The dual-screw canting system allows for precise alignment of the knee with the edge—a critical adjustment in competition to optimize the angle of attack based on the skier’s body type. The sturdy racing soles round out the package by providing a stable base that’s compatible with racing bindings.

The Rossignol HERO WORLD CUP ZJ+ ski boots are a competition tool designed for elite alpine skiers, available in sizes 25 and 26 as part of the Winter 2027 collection.
