The La Sportiva Spantik provides exceptional warmth for how light they are. I've been using these on pretty much all my climbs. The easy to use quick lacing system means I can get them on with just one hand. They keep my toes warm and feet dry, my two big criteria for mountaineering boots.

Outstanding warmth, comfort and feel

I used these on a 5 day Rainier expedition seminar in September. Spent most days on glaciers training or climbing on ice and rock. My feet were warm and I didn't feel I traded off any feel or connection with the terrain. As others have noted more boot than most need on Rainier during the summer but during colder months or on longer seminars it's really nice to pull out the inner boot and throw in your sleeping bag to keep warm overnight. Climbing ice, scrambling up rock, crossing ladders...this boot gives you the precision feel of a single boot. Lacing system looks awkward but it's easy, fast and I found more reliable at securing the right tension than laces. I noticed several RMI Guides wearing them as well but be aware the outer shell on theirs were really beat up and clearly not as durable as a plastic double boot. Buy from Whittaker. Their super knowledgeable team spent time helping me get the perfect fit and were flexible on returns.

Excellent boots, comfortable and warm. Excellent performance at the climb Elbrus.

Excellent boot. Extremely warm and comfortable. Have climbed ice in New England on cold days with always very warm feet. No better cold weather boot in my opinion. Remarkably lightweight considering how warm they are. If you get cold feet these are the boots for you.

Used these on engineer mountain, about 13k, in CO in January. I found them to be warm when moving, my feet did get slightly cold when not moving, but not a major issue. Loved the lacing system. Also used them ice climbing and they were great. A full size larger than my regular fit. I define them as the "least uncomfortable" boots I tried.

Very comfortable and warm. Have hiked in snow and ice, with and without crampons and feet stay warm and dry. One blister, but that is typical for me. Not as clunky as they appear. All in all an excellent boot. Glad that it comes in smaller sizes!

Sweet boots. Very warm. almost too warm. But I also purchased them with Denali in mind. Fit great with BD Sabretooth Pro crampons. Note on sizing. I have 44.5 Scarpa Baruns for backpacking. I have 46.5 in the Spantiks. Very adjustable for comfort. Had shin bang as well one day, but stopped and loosened up the tops and everything was fine.

The Bomb. I ordered these for Rainier, knowing full well that they would be overkill, but I also wanted to use them on McKinley. I took them up Rainier, and they were very comfortable. My feet felt snug, never cold, and very well supported. I got a little bit of "shin-bang" on my right shin, but it was minor. I haven't taken them up McKinley yet, so we'll see how that goes. The lacing system was easy to figure out. They worked perfect with my step-in crampons. We climbed the Kautz, and they felt very good in the ice chute. All in all, they were a little pricey, but the quality was very good. I recommend.

Mountaineering Boot Fit

How a boot fits is without question the most important factor of boot selection. While trekking boots and hiking shoes should fit the same as your street shoes, general and high alpine mountaineering boots are fit a little differently. A good fit correctly addresses the three dimensions of your foot.

Boot Fit Tips

Always Size Up - one-half to one full size. More room = more circulation = warm feet

Prevent Toe Bang - Half of mountain climbing is walking downhill. Make sure your toes do not touch the front of the boot. Test for this by lacing your boot up tightly and tapping your toe behind you. If your toes feel crunched against the end of the boot, size up.

Comparative Fit - They shouldn't fit like ski boots. Mountaineering boots are made for walking, so you should have a looser, roomy fit. Tight boots are a recipe for discomfort, decreased circulation and potential frostbite.

First Impressions - Have your sock system, lace up the boots and walk, stand sit, tap your toes and scuffle around for 15 minutes?

Brands and Models - If a boot fits too tight overall, you're likely in the wrong size. If the boot is pinching in some areas but is loose in other, your in the wrong brand or model. Boot brands used different lasts, even between different models.
