Its versatility is highlighted by the triple compatibility with Tour bindings, TRAB Tr2 safety bindings and mini tech bindings. The boot is equipped with a PEBAX® Rnew® bio-based shell and cuff with ergonomic support at the back and the “EASY 2 WEAR” system with a quick lock/release upper lever and a strap for micro regulation. The new, patented Ski/Walk “SWING-LOCK Closure System” protects mechanic parts from wear and impact and ensures a fast and secure closure of the boot. The EZ Flex™ Overlap Tongue allows for exceptional freedom of movement thanks to the hinge between the upper and lower part of the boot allowing for wider ankle movement. The patented, compact and precise Spider Buckle EVO™ closure system guarantees comfortable volumes at the bottom part of the boot and allows for perfect distribution of tension. The La Sportiva Grip Guard™ sole guarantees excellent performance over time. SOLAR: the dawn of a new era for ski mountaineering
