The Scarpa Inverno is a stiff mountaineering plastic boot crafted ready for extreme cold and high-altitude climbs. It's a solid option if you want:
This mountaineering boot uses a Vibram Stabeler made of Mont compound, which gives rigidity and durability. It has an undercut heel for braking. The widely-spaced lugs prevent snow and muck from building up, preventing slips and falls.
Likewise, this outsole is crampon-compatible. It is designed with a rockered bottom to facilitate a smoother stride.
The midsole of the Scarpa Inverno is made of ethylene-vinyl acetate (EVA) which gives great cushioning to the footwear. This type of foam is also able to attenuate shock from impacts, enhancing comfort.
The outer shell of this double-boot is a lightweight Pebax shell that is durable and waterproof. It maintains its flexibility even in cold temperatures. Its hinged ankle and soft plastic tongue grant flexibility.
The lacing hardware is rustproof, and a wrap-around rand protects against abrasion.
The removable inner boot is a multi-layer High Altitude Liner that gives insulation and cushioning. It has a separate lace-up closure for a secure foot lockdown.
