La Sportiva Spantik Mountain Boot

PRODUCT DESCRIPTION

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 and offers 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

A bantamweight 5 lbs. 1 oz. per pair
