    A ski-mountaineering and speed-touring machine.

    When you require a lightweight, precise, powerful boot for your next ski-mountaineering adventure, look no further than the Sideral Alpine Touring Boot from La Sportiva. The Sideral is made with a Grilamid shell that is extremely lightweight. To help maintain the lightness but improve power and skiability, La Sportiva added carbon fiber reinforcements throughout the shell of the boot. Since long days in boots tend to be the norm in the mountains, a thermo-moldable Palau 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 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 and the QuickBuckle upper 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 Outsole 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.

    • Familiarity:I've used it once or twice and have initial impressions

    If the price seems to good to be true, it is. The back support snapped on second day of use. I'm only 5' 7" 140lbs. Unless you can be sure that you never land in the back seat or crash then you will be fine. Suitable for the lightest of use only. I wouldn't dare attempt to ski at a resort with them.

    The good news is they will do a manufacture warranty if yours breaks within the first year of purchase. The bad news is they won't reimburse for shipping and it take two weeks for the whole process, keeping you sidelined during the winter. I like this company very much. Quite disappointed with this product.

    The back support is molded to give the look of carbon fiber. It is in fact plastic that does not hold up to the rigors of normal skiing. I bought mine when they were 40% off. Now they are 50% off. There is a reason for that.
