La Sportiva

Sideral 2.1 Alpine Touring Boot

When you require a lightweight, precise, and powerful boot for your next ski-mountaineering adventure, look no further than La Sportiva's Sideral 2.1 Alpine Touring Boot. The Sideral is made with a Grilamid shell that is extremely lightweight, with carbon fiber reinforcements in the cuff to maintain stiffness and power. Since long days in boots tend to be the norm in the mountains, a thermo-moldable liner mitigates any chafing or hot spots before they become a problem. 

To keep your feet from freezing during alternating belay pitches, La Sportiva put in a removable PU WarmSole insert that prevents the loss of heat through the bottom of the boot. When speed matters, you'll appreciate the ease of the Fast Lock System that allows you to switch from ski to walk mode with the flick of a switch. When in walk mode, these boots provide a hefty 68-degree cuff rotation, perfect for sections of more technical climbing. A LazerGrip sole with dual-density rubber positions climbing rubber where you need it for grip, and softer, shock-absorbing rubber under your heel and ball of your foot to allow you to go for longer.
