La Sportiva says: The cutting edge of mountain-boot technology, the Spantik (hint: it's a peak in the Karakoram Himal whose Golden Pillar is synonymous with extreme alpinism) combines all the latest, lightest materials to shave a full pound of the Nuptse and still offer unimpeachable climbing performance. Throw in the FLS (Fast Lacing System) and integral gaiter collar to keep spindrift out, and the summit is yours.
Based on the last of our tried-and-true Nuptse, which is step-in crampon compatible, and a proven performer for north faces, winter alpinism and long periods at altitude. Toasty inner boot features micro-perforated thermo-formable PE/Water-repellant Lorica® with Antiacqua® external coating, and a minimal outsole plate on the bottom for durability. Innovative lacing system (FLS) for inner and outer boots allows one-handed, gloved closure, even in the most heinous conditions.

Voted 5/5 | After being diagnosed with Raynaud's Phenomenon, I had to find a way to keep my feet warm---even in milder temperatures. After hearing Steve House speak about these at the Ouray Ice Festival, I bit the bullet and dropped the coin. I cannot say enough good things about these boots! I wear a women's 8.5 and ordered a 41, and while a bit on the high-volume side, my feet were warm---HOT, in fact, in the liners alone in my 0 degree bag while 9 degrees outside. They were a bit stiff at first, but after a day of snowshoeing in them, I found them to be very comfortable and easy to maneuver in. The lacing system---once you get the hang of it, is quick & dirty, though the lock tends to spin and you have to twist it back into place. I'd buy these boots again and again, and am excited to give them a wing-ding in the Sierras upcoming shortly and Rainier later in the season. | | Posted Mar 2, 2007 9:03 pm | | Bombchaser | Awsome | | 
Voted 5/5 | I have used these on only a few trips now, and have had no problems. I tried on a number of mountaineering boots and these fit like a pair of broke-in shoes. I love these boots with there simple, durable design. I haven't got to try them yet in sub-zero weather yet. I have done some technical couloir climbing up to 45 degrees with Grivel 14 crampons and had no problems. I highly recommend them so far. | | Posted Mar 7, 2008 12:57 am |
