Stellar is the all-round ski mountaineering boot dedicated to demanding female mountaineers in search of lightweight and freedom of movement, as well as safety and downhill response.
Stellar is a versatile female boot thanks to the exclusive triple compatibility with Tour bindings, TRAB Tr2 safety bindings and mini bindings. It is equipped with a Grilamid shell and a snug fitting cuff with ergonomic support at the back, the “EASY 2 WEAR” system, which speeds up fitting operations thanks to the quick lock/release mechanism of the upper lever and strap for micro-regulations. The new patented Ski/Walk mechanism “SWING-LOCK Closure System” avoids the exposure of mechanical parts to wear and impact and ensures a fast and secure closure. Exceptional freedom of movement is guaranteed by the innovative EZ Flex™ Overlap Tongue which, thanks to the upper and lower hinges, allows for wider ankle movement. Maximum customization of volume at the bottom of the boot is provided thanks to the patented, compact and precise Spider Buckle EVO™ that allows for perfect distribution of tension on the lower part of the boot. The La Sportiva Grip Guard™ sole guarantees excellent performance over time.
Stellar: the dawn of a new era for ski mountaineering.
Size: From 23 to26 ½ (mondo point).
