La Sportiva stratos VI


STRATOS VI is the sixth generation of the most famous full-carbon boot in its category. It is the lightest and most advanced ski touring race boot available on the market. The ergal “Stratos Lever” lever allows you to completely release the cuff from the shell, so you can take as many excursions as you like in Walk mode without any rubbing. The geometry and carbon lamination are designed to reduce weight and volumes to a minimum, while the shell is extremely compact allowing the foot to work in unison with the boot to give maximum control of movements, perfect power transmission and direct and precise action on the ski.

There are stiffening ribs and bullet-proof material inserts to reduce the vibrations of the shell and create an absolute top-performance ski as well as improving the reliability of the product in the harshest conditions.

The highly compact construction of the Spur Heel Construction™ adds strength and leaves the heel free for compatibility with all types of crampons. Now toe and heel comply with ISFM regulations. The rear attachment binding system is made with polymeric material is in the characteristic yellow colour, protects the shell from impact while walking.
STRATOS has always set the standard in the category.
