LA SPORTIVA SIDERAL SKI BOOTS

The Sideral is comprised of a low profile Grilamid® shell and a PA12 Nylon cuff. La Sportiva's patent pending Fast Lock System™ closure consists of the unique Vertebra Technology™, a hardwearing ergonomic power structure that works like a backbone, and the innovative Cam Closure System™, which allows for the transition from ski to walk mode in just one super-fast movement guaranteeing a perfect comfortable lockdown fit. The Sideral features maximum freedom of movement thanks to the EZ Flex™ system incorporated into the Pebax® tongue while the shell’s ergonomic profile facilitates the walk mode and enhances the general level of comfort thus allowing power to be conveyed directly to the skis. The removable WarmSole™ insole creates an insulating barrier against cold and make this one of the warmest in the two-buckle category.
