Manaslu 8000 Technology

A project developed with Asolo Test Team developed for Himalayan Mountaineering technical and extreme use in cold environments. It’s made of three boots in one: the outer gaiter, the main shell and the inner boot and it’s been developed using two different lasts: one for the main shell and one for the inner boot. Plus, it’s been developed with two different constructions: lasted (main shell) and slip lasted (inner boot).


The four-material used guarantee lightweight and resistant to abrasion while the Gore-Tex Extended Comfort Footwear lining guarantees waterproofness and breathability. The YKK Zip closure system is fast, waterproof and precise zip. The PU rand all around gives additional protection.


The five materials used give lightness, resistance and support. The step-in technology allows an easy and fast step in of the inner boot into the shell. The dual Winch lacing system guarantee the most precise lace up.


The step-in technology is made of three steps which are: insert the inner boot into the shell, lock the rear flap and the front double dial system and you're ready to climb.

This double lacing system gives the possibility of tightening and un-tightening the wire with one hand thanks to its dial. The first Winch locks the ankle and the top part while the second Winch locks the instep and front part. Precise and fast lacing system.


Five different materials for the maximum comfort, support and warmth (guaranteed by Primaloft). The fast lock closure system is fast and precise. The RECCO Rescue System has been added for safety.


1. Six layers of carbon fiber lasting board
It’s made of six different layers of carbon fiber. The carbon fiber is positioned at 45° in order to reduce the torsion. The carbon fiber is positioned in the order of length in order to improve the stiffness. The carbon fiber lasting board is perfect for the anti-torsional action, for giving great support and stability.

2. TPU crampon attachments (rear part)

3. Mono density microporous midsole

4. TPU crampon attachments (front part)

5. Vibram Betulla expanded rubber outsole + Vibram Mont Compound in the front
